#EV Batteries Good, Paper EV Batteries 10x Better No matter how fast the cost of oil drops, it just can keep up with the pace of improvements in electric vehicle batteries.
In the latest development, a team of researchers at the University of California, Riverside, has come up with a paperlike material that could bring in a new generation of high-range batteries.
The new EV battery announcement from the school Bourns College of Engineering, involves a new paperlike material made from silicon in the form of spongy silicon nanofibers.
So Paper EV Batteries, So What? The silicon apercould replace graphite in conventional lithium-ion EV batteries,
and that where things start to get really exciting. In a conventional battery, the anode (along with the cathode, the anode is responsible for charging
its electrical charger per unit weight of the battery is almost 10 times more than graphite.
However and there always a however silicon tends to degrade the battery when it expands.
enabling the battery to cycle hundreds of times without degrading. In the illustration below, you can see the upcycling process at work:
which would help shave down the cost of EV batteries. You can get all the details from the research team article, owards Scalable Binderless Electrodes:
the team will be working on scaling up the technology into a larger format for EV batteries.

That Google would choose Solid Energy as a potential partner for such a huge project seems to speak well of the startup new battery materials. he reason wee focusing on the materials side is that it where we can add the most value,
Lithium-ion batteries have become more high-profile recently because of the very notable success of the Tesla Model S
and indirectly by driving battery costs down to create storage for distributed renewables. This all then unleashes competition across sectors bringing new players to old industries.
battery manufacturers, copper and lithium miners, electronics producers, software developers, electric engine makers, smart grid builders and, of course, solar and wind power manufacturers, installers and financiers.
It that competing energy products of renewables and batteries, in a system with electric vehicles, will behave as a disruptive technology always does,
and Google who are both developing battery and car opportunities, with a close eye on the technology integration opportunity.

#New aluminum air battery could blow past lithium-ion runs on water As battery technologies go,
The company is claiming that its new aluminum-air batteries can run for up to two weeks and be refilled with normal water.
How an aluminum-air battery works First, some basics. The problem with battery technology isn whether or not we can build better batteries as the chart below shows,
we can build batteries that blow traditional lithium-ion out of the water. Keep in mind that the chart below is exponential,
meaning that fuel cell technology has 10 times the energy density of a typical cobalt-Li ion battery.
The various etal-Airbatteries including zinc-air, aluminum-air, and lithium-air, have some of the highest energy densities its possible to build.
The studies in question are aimed all at enhancing the performance of Al-air batteries while extending their useful lifetimes typically,
creating a secondary aluminum-air battery adjacent to the primary buffered the accumulation of byproducts that normally prevent the battery from working properly over the long term.
The echargabilityof Al-air batteries requires some explanation. Al-air batteries are primary cells, which means they can be recharged via conventional means.
As the aluminum anode is consumed by contact with oxygen, hydrated aluminum forms as a byproduct.
which is why the batteries are referred to as rechargeable. Periodically, the aluminum anode will have to be replaced it not clear how often the Fuji Pigment battery would need servicing of this sort.
Could Al-air be the next big thing? New battery technologies and announcements are a dime a dozen,
Al-air batteries have actually been used in specialized military applications for years, which is important it means there some preexisting expertise
The hydrated aluminum oxide solution produced during the battery normal operation would need to be recycled in some fashion
(and the weight of the aluminum anode in these batteries is unknown), but the team that performed that analysis noted that proper recycling would put Al-air in the same cost range as conventional internal combustion engines.
#irigamistretchable batteries could herald flexible electronics era Fitness trackers and smartwatches aren known for their battery life,

%the kirigami battery remained intact, and the Gear 2 smartwatch continued its video playback. ASU leader Dr. Jiang says that the kirigami-based design is the secret to the future of flexible electronics. he kirigami-based methodology can be expanded readily to other applications to develop highly stretchable devices
The goal behind stretchable batteries is to create mobile computing devices that are fully flexible devices that need not sacrifice elegance for functionality Flexible batteries will allow devices to become thinner, lighter,
and more formal while leaving room for two batteries to be placed inside a device instead of just one.
The Gear 2 300mah battery, as stated in the report, could become a 600mah battery that keeps a smartwatch

#24m Unveils the Reinvented Lithium-Ion Battery Five years ago, M24 Technologies spun out from parent company A123 with plans to turn a mysterious,
semisolid electrode material into a revolution in how lithium-ion batteries are designed and built. Back then, cofounder and Massachusetts institute of technology professor Yet-Ming Chiang described a lean sheet of paperapproach, combining concepts from flow batteries and fuel cells,
and stripping the modern lithium-ion battery architecture of all its inactive materials and complex manufacturing steps.
-based startup unveiled the results--a lithium-ion battery that it says can be built at $100 per kilowatt-hour at scale,
24m says its manufacturing facilities could be one-tenth the cost of today battery plants,
modular packages. obody ever made a battery this way, Chiang said in a phone interview last week. 24m has made about 10,000 test cells so far,
Compared to the multi-stage process used in today lithium-ion batteries, it implified, streamlined, with a lot of metrology,
as well as established battery giants like Samsung, Panasonic and LG Chem. Breakthroughs being promised by startups with new nano-structured materials and designs, such as Amprius, Nanosys,
could enable even greater performance and cost improvements for traditional battery designs. And outside lithium-ion batteries, a host of new chemistries from startups such as Aquion, Eos Energy storage and a long list of flow battery contenders are promising low-cost
multi-hour energy storage solutions at utility scale. Given the novelty of what 24m is promising, it likely to be met with a skeptical eye by the industry until it starts delivering a testable product at scale.
So how does 24m approach make for an entirely new way of designing and building lithium-ion batteries?
he said. ut what we realized upon forming the company was that this semisolid electrode capability had a much better home--reinventing how lithium-ion batteries are made.
Chiang identified two main problems in today lithium-ion battery design. ne is that the current lithium-ion battery itself contains a great deal of material that doesn store any energy
He referring to the inactive material that layered between the super-thin electrodes that allow today lithium-ion batteries to charge
and to create a battery that has much thicker electrodes, and thus much less inactive materials. p until now, it has not been possible to create electrodes that are this thick
That necessary for the lithium ions to get out of the back of the battery, he said.
is a battery cell that combines high energy capacity and high current density in the same set of materials,
as compared to typical lithium-ion batteries for power tools, tablets and electric vehicles. At the same time, e believe these to be the safest lithium-ion batteries ever created,
he said, largely due to the lack of brittle, breakable separator materials within the battery cells.
To prove that, 24m shared a series of photographs of a test pouch cell being folded up like an accordion
we left the battery on the shelf for a month and it still worked, he said.
That not just a safety bonus--it also shows that you can shape the battery,
Chiang said. hy does a conventional lithium-ion battery plant have to be so expensive and so large?
First of all, a conventional lithium-ion battery plant starts with metal foil, and then layers liquid nk or painton it to form its electrodes,
Others have tried to adapt similar manufacturing processes to the battery business before, he noted. or example,
people have tried to make extruded batteries, he said, but hey had to have so much plastic to make that process possible,
and a really poorly performing battery. That in contrast to 24m process, in which hat goes into the electrodes is just
much simpler than the processes used to make lithium-ion batteries today. he formulation process for making these electrodes is spent exacting,
using commercial off-the-shelf gear in common use in today battery manufacturing plants, as well as from industries with less of a reputation for cutting edge technology,
many gigawatt-hours of batteries produced every year. We believe the most cost-efficient way to get there is to create manufacturing modules that you can just replicate
