#Making Batteries with Portabella Mushrooms Can portabella mushrooms stop cell phone batteries from degrading over time?
They have created a new type of lithium-ion battery anode using portabella mushrooms, which are inexpensive, environmentally friendly and easy to produce.
The current industry standard for rechargeable lithium-ion battery anodes is synthetic graphite, which comes with a high cost of manufacturing
With the anticipated increase in batteries needed for electric vehicles and electronics, a cheaper and sustainable source to replace graphite is needed.
That porosity is important for batteries because it creates more space for the storage and transfer of energy, a critical component to improving battery performance.
In addition, the high potassium salt concentration in mushrooms allows for increased electrolyte-active material over time by activating more pores
and current-collector free approach to anode fabrication. ith battery materials like this, future cell phones may see an increase in run time after many uses, rather than a decrease,
Hierarchically Porous Carbon Anodes for Li-ion Batteries, published on Sept. 29 in the journal Nature Scientific Reports.
which is important for battery electrodes because such architectures possess a very large surface area for the storage of energy, a critical component to improving battery performance.
One of the problems with conventional carbons, such as graphite, is that they are prepared typically with chemicals such as acids
such as the skin of the caps of portabella mushrooms, for making batteries. It is expected that nearly 900,000 tons of natural raw graphite would be needed for anode fabrication for nearly six million electric vehicle forecast to be built by 2020.
This paper involving mushrooms is published just over a year after the Ozkan labs developed a lithium-ion battery anode based on nanosilicon via beach sand as the natural raw material.

#Discovery about new battery overturns decades of false assumptions New findings at Oregon State university have overturned a scientific dogma that stood for decades,
by showing that potassium can work with graphite in a potassium-ion battery a discovery that could pose a challenge and sustainable alternative to the widely-used lithium-ion battery.
Lithium-ion batteries are ubiquitous in devices all over the world, ranging from cell phones to laptop computers and electric cars.
But there may soon be a new type of battery based on materials that are far more abundant and less costly.
A potassium-ion battery has been shown to be possible. And the last time this possibility was explored was
or other bulk carbon anodes in a battery, said Xiulei (David) Ji, the lead author of the study
because they open some new alternatives to batteries that can work with well-established and inexpensive graphite as the anode,
The new findings show that it can work effectively with graphite or soft carbon in the anode of an electrochemical battery.
Right now, batteries based on this approach don have performance that equals those of lithium-ion batteries,
he said. t safe to say that the energy density of a potassium-ion battery may never exceed that of lithium-ion batteries,
and be ready to take the advantage of the existing manufacturing processes of carbon anode materials. lectrical energy storage in batteries is essential not only for consumer products such as cell phones and computers,

#Aluminium battery can charge phone in one minute, scientists say Scientists say they have invented a new battery that could fully charge a smartphone in just one minute.
The researchers have created an aluminium battery which they hope could replace the lithium models commonly found in laptops and mobile phones.
And as well as the nprecedented charging timesof their aluminium prototype, the team said it was also safer than lithium-ion batteries as it was less prone to catching fire and more environmentally friendly than alkaline models such as AA and AAA.
Publishing the findings in the journal Nature Hongjie Dai, a professor of chemistry at Stanford university, hailed it as a breakthrough in battery technology that went further than previous attempts using aluminium.
He said: e have developed a rechargeable aluminium battery that may replace existing storage devices, such as alkaline batteries,
which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames.
Our new battery won catch fire, even if you drill through it. illions of consumers use 1. 5-volt AA and AAA BATTERIES.
Our rechargeable aluminium battery generates about two volts of electricity. That higher than anyone has achieved with aluminium.
The prototype was said to be more durable, withstanding more than 7, 500 cycles without any loss of capacity and surpassing previous aluminium batteries
which died after just 100 charge-discharge cycles, while a typical lithium-ion battery lasts about 1,
000 cycles. his was the first time an ultra-fast aluminium-ion battery was constructed with stability over thousands of cycles,
the report authors wrote. Dai added that lithium batteries could o off in an unpredictable mannerand cited a ban by US airlines Delta
and United on bulk shipments on passenger planes. And the new design could be used to store renewable energy of the electrical grid, the researchers suggested.
Meanwhile, co-author Ming Gong said: nother feature of the aluminium battery is flexibility. You can bend it
and fold it, so it has the potential for use in flexible electronic devices. Aluminium is also a cheaper metal than lithium. p

Fuel cell systems represent a promising alternative for low carbon emission energy production. Traditional fuel cells are limited however by the need of efficient catalysts to drive the chemical reactions involved in the fuel cell.
Historically platinum and its alloys have frequently been used as anodic and cathodic catalysts in fuel cells
but the high cost of platinum due to its low abundance motivates researchers to find efficient catalysts based on earth-abundant elements.
#Smart lithium-ion battery warns of fire hazard Stanford university scientists have developed a smart lithium-ion battery that gives ample warning before it overheats
The new technology is designed for conventional lithium-ion batteries now used in billions of cellphones laptops and other electronic devices as well as a growing number of cars and airplanes.
The system can detect problems that occur during the normal operation of a battery but it does not apply to batteries damaged in a collision or other accident.
Cui and his colleagues describe the new technology in a study published in the Oct 13 issue of the journal Nature Communications.
Lowering the oddsa series of well-publicized incidents in recent years has raised concern over the safety of lithium-ion batteries.
In 2013 the Boeing aircraft company temporarily grounded its new 787 Dreamliner fleet after battery packs in two airplanes caught fire.
In 2006 the Sony Corporation recalled millions of lithium-ion batteries after reports of more than a dozen consumer-laptop fires.
The company said that during the manufacturing process tiny metal impurities had gotten inside the batteries causing them to short-circuit.
We want to lower the odds of a battery fire to one in a billion or even to zero.
A typical lithium-ion battery consists of two tightly packed electrodes--a carbon anode and a lithium metal-oxide cathode--with an ultrathin polymer separator in between.
If it's damaged the battery could short-circuit and ignite the flammable electrolyte solution that shuttles lithium ions back and forth.
so that lithium ions can flow between the electrodes as the battery charges and discharges. Manufacturing defects such as particles of metal and dust can pierce the separator
if the battery is charged too fast or when the temperature is too low--a phenomenon known as overcharge.
and eventually make contact with the cathode causing the battery to short. Smart separatorin the last couple of years we've been thinking about building a smart separator that can detect shorting before the dendrites reach the cathode said Cui a member of the photon science faculty at the SLAC National Accelerator Laboratory
That lets you know that the dendrites have grown halfway across the battery. It's a warning that the battery should be removed before the dendrites reach the cathode and cause a short circuit.
The build up of dendrites is most likely to occur during charging not during the discharge phase
when the battery is being used. You might get a message on your phone telling you that the voltage has dropped to zero so the battery needs to be replaced Zhuo said.
That would give you plenty of lead-time. But when you see smoke or a fire you have to shut down immediately.
when a battery is likely to fail. Locating defectsin addition to observing a drop in voltage co-lead author Hui Wu was able to pinpoint where the dendrites had punctured the copper conductor simply by measuring the electrical resistance between the separator and the cathode.
Adding this thin conducting layer doesn't change the battery's performance but it can make a huge difference as far as safety.
Most lithium-ion batteries are used in small electronic devices. But as the electric vehicle market expands
The bigger the battery pack the more important this becomes Cui added. Some electric cars today are equipped with thousands of lithium-ion battery cells.
If one battery explodes the whole pack can potentially explode. The early-warning technology can also be used in zinc aluminum and other metal batteries.
It will work in any battery that would require you to detect a short before it explodes Cui said.

The battery will also have a longer lifespan of over 20 years. Expected to be the next big thing in battery technology this breakthrough has a wide-ranging impact on many industries especially for electric vehicles
which are inhibited currently by long recharge times of over 4 hours and the limited lifespan of batteries.
This next generation of lithium-ion batteries will enable electric vehicles to charge 20 times faster than the current technology.
With it electric vehicles will also be able to do away with frequent battery replacements. The new battery will be able to endure more than 10000 charging cycles--20 times more than the current 500 cycles of today's batteries.
NTU Singapore's scientists replaced the traditional graphite used for the anode (negative pole) in lithium-ion batteries with a new gel material made from titanium dioxide an abundant cheap and safe material found in soil.
It is used commonly as a food additive or in sunscreen lotions to absorb harmful ultraviolet rays.
Naturally found in a spherical shape NTU Singapore developed a simple method to turn titanium dioxide particles into tiny nanotubes that are a thousand times thinner than the diameter of a human hair.
what helps to speeds up the chemical reactions taking place in the new battery allowing for superfast charging.
NTU professor Rachid Yazami who was the co-inventor of the lithium-graphite anode 34 years ago that is used in most lithium-ion batteries today said Prof Chen's invention is the next
big leap in battery technology. While the cost of lithium-ion batteries has been reduced significantly and its performance improved
since Sony commercialised it in 1991 the market is fast expanding towards new applications in electric mobility
Ideally the charge time for batteries in electric vehicles should be less than 15 minutes which Prof Chen's nanostructured anode has proven to do.
and is currently developing new types of batteries for electric vehicle applications at the Energy Research Institute at NTU (ERI@N). Commercialisation of technologymoving forward Prof Chen's research team will be applying for a Proof-of-Concept
grant to build a large-scale battery prototype. The patented technology has attracted already interest from the industry.
and Prof Chen expects that the new generation of fast-charging batteries will hit the market in two years'time.
Equally important we can now drastically cut down the waste generated by disposed batteries since our batteries last ten times longer than the current generation of lithium-ion batteries The long-life of the new battery also means drivers save on the cost of a battery replacement
which could cost over USD$5000 each. Easy to manufactureaccording to Frost & Sullivan a leading growth-consulting firm the global market of rechargeable lithium-ion batteries is projected to be worth US$23. 4 billion in 2016.
Lithium-ion batteries usually use additives to bind the electrodes to the anode which affects the speed in
which electrons and ions can transfer in and out of the batteries. However Prof Chen's new cross-linked titanium dioxide nanotube-based electrodes eliminate the need for these additives
and can pack more energy into the same amount of space. Manufacturing this new nanotube gel is very easy Prof Chen added.
Battery manufacturers will find it easy to integrate our new gel into their current production processes.
This battery research project took the team of four NTU Singapore scientists three years to complete
Last year Prof Yazami was awarded the Draper Prize by the National Academy of Engineering for his ground-breaking work in developing the lithium-ion battery with three other scientists.

#Half Price Lithium-ion Batteries With Improved Performance and Recyclability MIT spinoff company 24m has reinvented the manufacturing process for lithium-ion batteries to reduce cost,
An advanced manufacturing approach for lithium-ion batteries, developed by researchers at MIT and at a spinoff company called 24m,
promises to significantly slash the cost of the most widely used type of rechargeable batteries while also improving their performance
says Yet-Ming Chiang, the Kyocera Professor of Ceramics at MIT and a cofounder of 24m (and previously a cofounder of battery company A123).
The existing process for manufacturing lithium-ion batteries, he says, has changed hardly in the two decades
In this so-called low battery, the electrodes are suspensions of tiny particles carried by a liquid
and pumped through various compartments of the battery. The new battery design is a hybrid between flow batteries and conventional solid ones:
In this version, while the electrode material does not flow, it is composed of a similar semisolid, colloidal suspension of particles.
Chiang and Carter refer to this as a emisolid battery. impler manufacturing processthis approach greatly simplifies manufacturing,
and also makes batteries that are flexible and resistant to damage, says Chiang, who is senior author of a paper in the Journal of Power Sources analyzing the tradeoffs involved in choosing between solid
and flow-type batteries, depending on their particular applications and chemical components. This analysis demonstrates that
while a flow battery system is appropriate for battery chemistries with a low energy density (those that can only store a limited amount of energy for a given weight),
for high-energy density devices such as lithium-ion batteries, the extra complexity and components of a flow system would add unnecessary extra cost.
Almost immediately after publishing the earlier research on the flow battery, Chiang says, e realized that a better way to make use of this flowable electrode technology was to reinvent the lithium ion manufacturing process. nstead of the standard method of applying liquid coatings to a roll of backing material,
thicker electrodes, the system reduces the conventional battery architecture number of distinct layers, as well as the amount of nonfunctional material in the structure, by 80 percent.
Bendable and foldablein addition to streamlining manufacturing enough to cut battery costs by half, Chiang says,
the new system produces a battery that is more flexible and resilient. While conventional lithium-ion batteries are composed of brittle electrodes that can crack under stress
the new formulation produces battery cells that can be bent, folded or even penetrated by bullets without failing.
This should improve both safety and durability, he says. The company has made so far about 10,000 batteries on its prototype assembly lines, most
of which are undergoing testing by three industrial partners, including an oil company in Thailand and Japanese heavy-equipment manufacturer IHI Corp. The process has received eight patents
By 2020, Chiang estimates that 24m will be able to produce batteries for less than $100 per kilowatt-hour of capacity.
when is it better to build a flow battery versus a static model. This paper will serve as a key tool for making design choices
and go-no go decisions. iswanathan adds that 24m new battery design ould do the same sort of disruption to lithium ion batteries manufacturing as
however, will require extremely low-power sensors that can run for months without battery changes or, even better, that can extract energy from the environment to recharge.
Where its predecessors could use a solar cell to either charge a battery or directly power a device,
and it can power the device directly from the battery. All of those operations also share a single inductor the chip main electrical component which saves on circuit board space
Nonetheless, the chip power consumption remains low. e still want to have battery-charging capability, and we still want to provide a regulated output voltage,
Ups and downs The circuit chief function is to regulate the voltages between the solar cell, the battery,
If the battery operates for too long at a voltage that either too high or too low
one of their biggest limitations is the capacity of their tiny batteries to deliver enough power to transmit data.
At the moment, the coin-sized batteries used in many small electronic devices have limited very ability to deliver a lot of power at once,
Small batteries are suited generally poorly for such power needs, he adds. e know it a problem experienced by a number of companies in the health-monitoring
So an alternative is to go to a combination of a battery and a capacitor, Hunter says:
the battery for long-term, low-power functions, and the capacitor for short bursts of high power. Such a combination should be able to either increase the range of the device,
