or without batteries. ur ultimate goal is to replace the battery of an implant altogether,

ut even extending the life of the implant own battery is useful. They grew rat smooth muscle cells on their prototypes to determine that the materials were not toxic.

The potential to eliminate batteries or, at least, the need to replace them frequently represents a source of motivation for continued work in these and related directions. e

or using batteries, but both approaches have considerable drawbacks. Grid-connected sensors need cables, limiting where they can be used,

while battery-powered ones only last as long as their battery life. But what if sensors could harness energy directly from their environment from the sun, from ambient heat, from radio waves or vibrations?

and the SWAP coordinator at CTTC in Spain, says the design of energetically self-sufficient networks differs sharply from that of standard battery-powered ones. he goal is no longer to minimise energy draw so as to maximise the lifetime of the battery reserve,

But it has the potential to eliminate bulky batteries and clumsy recharging systems and lead to a type of medicine where physicians treat disease

But it is possible to build tiny batteries into microimplants, and then recharge these batteries wirelessly using the midfield system.

This is not possible with today technologies. ith this method we can safely transmit power to tiny implants in organs like the heart or brain,

A number of battery-free technologies exist that are powered by solar and ambient radio frequency waves.

#AAA BATTERY powers cheap water splitter A new device uses a regular AAA BATTERY to split water into hydrogen and oxygen.

The hydrogen gas could power fuel cells in zero emissions vehicles. The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas.

Unlike other water splitters that use precious-metal catalysts the electrodes in the Stanford device are made of inexpensive and abundant nickel

Fuel cell technology is essentially water splitting in reverse. A fuel cell combines stored hydrogen gas with oxygen from the air to produce electricity

which powers the car. The only byproduct is water unlike gasoline combustion which emits carbon dioxide a greenhouse gas.

In 2015 American consumers will finally be able to purchase fuel cell cars from Toyota and other manufacturers.

#New battery turns wasted heat into energy Stanford university rightoriginal Studyposted by Dan Stober-Stanford on May 22 2014researchers have developed a new battery technology that captures low-temperature waste heat

and refining release tremendous amounts of low-grade heat to ambient temperaturessays Yi Cui an associate professor of materials science and engineering at Stanford university. ur new battery technology is designed to take advantage of this temperature gradient at the industrial scale. he new system

which states that the voltage of a rechargeable battery is dependent on temperature. o harvest thermal energy we subject a battery to a four-step process:

First an uncharged battery is heated by waste heat. Then while the battery is still warm a voltage is applied.

Once fully charged the battery is allowed to cool. Because of the thermogalvanic effect the voltage increases as the temperature decreases.

When the battery has cooled it actually delivers more electricity than was used to charge it. That extra energy doesn t appear from nowhere explains Cui.

It comes from the heat that was added to the system. The system aims at harvesting heat at temperatures below 100 C which accounts for a major part of potentially harvestable waste heat. ne-third of all energy consumption in the United states ends up as low-grade heatsays co-lead author Yuan

In the experiment a battery was heated to 60 C charged and cooled. The process resulted in an electricity-conversion efficiency of 5. 7 percent almost double the efficiency of conventional thermoelectric devices.

or more says Yang who notesâ that most heat recovery systems work best with higher temperature differences. key advance is using material that was not around at that timefor the battery electrodes as well as advances in engineering the system says co-author Gang Chen a professor

and manufacturing processes that are used already widely in the battery industryadds Lee. While the new system has a significant advantage in energy conversion efficiency over conventional thermoelectric devices it has a much lower power densityâ##that is the amount of power that can be delivered for a given weight.

and improve the speed of battery charging and discharging Chen adds. t will require a lot of work to take the next step. here is currently no good technology that can make effective use of the relatively low-temperature differences this system can harness Chen says. his has an efficiency we think is quite attractive.

At the moment however the laboratory prototype is about the size of A d-cell battery and looks like a chemistry experiment with two electrodes one positive the other negative plunged into a bottle of wastewater.

and produce electricity that is captured by the battery s positive electrode. e call it fishing for electronssays Craig Criddle a professor in the department of civil and environmental engineering at Stanford university.

What is new about the microbial battery is a simple yet efficient design that puts these exoelectrogenic bacteria to work.

As reported in the Proceedings of the National Academy of Sciences at the battery s negative electrode colonies of wired microbes cling to carbon filaments that serve as efficient electrical conductors.

At that point it is removed from the battery and re-oxidized back to silver oxide releasing the stored electrons.

Engineers estimate that the microbial battery can extract about 30 percent of the potential energy locked up in wastewater.

Even so the microbial battery is worth pursuing because it could offset some of the electricity now used to treat wastewater.

and is designed to work with PV solar panels and batteries, to continually generate water even in emergency situations.

so that it can can carry the battery, electronic centers, and all the other things necessary for autonomous flight.

In theory, they would just have to come back to something to recharge their batteries. But we re very early on in working this out.

That s important for the battery and other electronics and sensors. Once the robot can stay aloft on its own,

#Beating battery drain Stream video on your smartphone or use its GPS for an hour or two and you ll probably see the battery drain significantly.

As data rates climb and smartphones adopt more power-hungry features battery life has become a concern.

Now a technology developed by MIT spinout Eta Devices could help a phone s battery last perhaps twice as long

The primary culprit in smartphone battery drain is an inefficient power amplifier a component that is designed to push the radio signal out through the phones antennas.

This means smartphone batteries lose longevity and base stations waste energy and lose money. But Eta Devices has developed a chip (for smartphones)

You can look at our technology as a high-speed gearbox that every few nanoseconds modulates the amount of power that the power amplifier draws from the battery explains Joel Dawson Eta Devices chief technology officer

Dawson says this could potentially double current smartphone battery life. Besides battery life Dawson adds there are many ways the telecommunications industry can take advantage of improved efficiency.

Eta Devices approach could lead to smaller handset batteries for example and even smaller handsets since there would be less dissipating heat.

The technology could also drive down operating costs for base stations in the developing world where these stations rely on expensive diesel fuel for power

#Nanoparticle network could bring fast-charging batteries (Phys. org) A new electrode design for lithium-ion batteries has been shown to potentially reduce the charging time from hours to minutes by replacing the conventional graphite electrode with a network of tin-oxide nanoparticles.

Batteries have called two electrodes an anode and a cathode. The anodes in most of today's lithium-ion batteries are made of graphite.

The theoretical maximum storage capacity of graphite is limited very at 372 milliamp hours per gram hindering significant advances in battery technology said Vilas Pol an associate professor of chemical engineering at Purdue University.

The researchers have performed experiments with a porous interconnected tin-oxide based anode which has nearly twice the theoretical charging capacity of graphite.

Without the proper pore size and interconnection between individual tin oxide nanoparticles the battery fails. The research paper was authored by Etacheri;

The group came up with a method that uses solar panels to charge a bank of batteries.

The batteries then power a system that removes salt from the water through electrodialysis. On the most basic level, that means that dissolved salt particles,

but powering sensors--even really efficient sensors--requires some form of electric charging or battery replacement.

#New lithium ion battery is safer, tougher, and more powerful Lithium ion batteries (LIBS) are a huge technological advancement from lead acid batteries

which have existed since the late 1850. Thanks to their low weight, high energy density and slower loss of charge when not in use, LIBS have become the preferred choice for consumer electronics.

Lithium-ion cells with cobalt cathodes hold twice the energy of a nickel-based battery and four times that of lead acid.

Despite being a superior consumer battery, LIBS still have some drawbacks. Current manufacturing technology is reaching the theoretical energy density limit for LIBS

These types of batteries, in all of their different lithium-anode combinations, continue to be an essential part of modern consumer electronics

The Korean team tried a totally new approach in making the batteries. According to Dr. Kimoon Kim at IBS, e have investigated already high

and highly anisotropic directionally dependent proton conducting behaviors in porous CB 6 for fuel cell electrolytes.

The new battery is built from pumpkin-shaped molecules called cucurbit 6 uril (CB 6) which are organized in a honeycomb-like structure.

The physical structure of the porous CB 6 enables the lithium ions to battery to diffuse more freely than in conventional LIBS

and exist without the separators found in other batteries. In tests the porous CB 6 solid electrolytes showed impressive lithium ion conductivity.

To compare this to existing battery electrolytes, the team used a measurement of the lithium transference number (tli)

They also subjected the batteries to extreme temperatures of up to 373 K (99.85°C), well above the 80°C typical upper temperature window for exiting LIBS.

In the tests, the batteries were cycled at temperatures between 298 K and 373 K (24.85°C and 99.85°C) for a duration of four days and after each cycle the results showed no thermal runaway and hardly any change in conductivity.
