#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
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.
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.

The new device that Pint and Westover have developed is a supercapacitor that stores electricity by assembling electrically charged ions on the surface of a porous material instead of storing it in chemical reactions the way batteries do.
and operate for millions of cycles instead of thousands of cycles like batteries. In a paper appearing online in the journal Nano Letters Pint
One area where supercapacitors lag behind batteries is in electrical energy storage capability: Supercaps must be larger and heavier to store the same amount of energy as lithium-ion batteries.
However the difference is not as important when considering multifunctional energy storage systems. attery performance metrics change when you re putting energy storage into heavy materials that are needed already for structural integritysays Pint. upercapacitors store ten times less energy than current lithium-ion batteries
but they can last a thousand times longer. That means they are suited better for structural applications.
Sandwiched between the two electrodes is a polymer film that acts as a reservoir of charged ions similar to the role of the electrolyte paste in a battery.
There have also been recent press reports of several major efforts to develop multifunctional materials or structural batteries for use in electric vehicles and for military applications.
The results can be seen in batteries that drain faster and increasing heat dissipation that can damage delicate electronic circuits.
while draining the battery requires frequent replacement surgery. The researchers led by Suman Datta professor of electrical engineering tuned the material composition of the indium gallium arsenide/gallium arsenide antimony

and spontaneously heals tiny cracks that develop during battery operation. elf-healing is very important for the survival and long lifetimes of animals
For the battery project Chao added tiny nanoparticles of carbon to the polymer so it would conduct electricity. e found that silicon electrodes lasted 10 times longer
it has a high capacity for soaking up lithium ions from the battery fluid during charging and then releasing them
when the battery is put to work. But this high capacity comes at a price: silicon electrodes swell to three times their normal size
and shrink back down again each time the battery charges and discharges. The brittle material soon cracks and falls apart degrading battery performance.
This is a problem for all electrodes in high-capacity batteries says Hui Wu a former Stanford postdoc who is now a faculty member at Tsinghua University in Beijing
The device wirelessly converts the microwave signal to direct current voltage capable of recharging a cell phone battery or other small electronic device according to a report appearing in Applied Physics Letters.

and co-first author on the JACS publication. ut a lithium-sulfur battery is not a stable system as its capacity tends to fade over a short period of time. fter about 50 charge cycles the energy density of a lithium-sulfur
battery decreases rapidly due to a phenomenon called the polysulfide shuttling effect which is when the polysulfide chains in the battery s cathode (positive end) dissolve in the electrolyte the ionizing liquid that allows electrons to flow.
To combat this problem and stabilize the sulfur the researchers used amylopectin a polysaccharide that s a main component of corn starch. he corn starch can effectively wrap the graphene oxide-sulfide composite through the hydrogen bonding to confine the polysulfide among the carbon layerssays Hao Chen

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.

After 50 charge-discharge cycles, the proof-of-concept units retained a capacity that was still more than double that of the graphite currently used for LI battery anodes.
One area ripe for improvement is the humble battery. In an increasingly mobile world battery capacity is becoming a bottleneck that generally limits devices to less than a day worth of use.
In the new experiments, the Rice lab mixed graphene nanoribbons and tin oxide particles about 10 nanometers wide in a slurry with a cellulose gum binder and a bit of water, spread it on a current collector
and encased it in a button-style battery. GNRS are a single atom thick and thousands of times longer than they are wide.
GNRS could also help overcome a prime difficulty with LI battery development. Lithium ions tend to expand the material they inhabit,
GNRS take a different approach by giving batteries a degree of flexibility, Tour says. raphene nanoribbons make a terrific framework that keeps the tin oxide nanoparticles dispersed
Lin says the lab plans to build batteries with other metallic nanoparticles to test their cycling and storage capacities.
