to demonstrate how batteries work. To make a battery from organic material all you need is two metals oe an anode,

which is the negative electrode, such as zinc, and a cathode, the positively charged electrode, such as copper.

Others have made"earth batteries  using two metal plates and a pile of dirt, or a bucket of water.

"but enough to construct a battery that could charge mobile phones or laptops in places where there is no grid, no power connection.

 Their cost analyses suggested that a single boiled potato battery with zinc and copper electrodes generates portable energy at an estimated $9 per kilowatt hour,

which is 50-fold cheaper than a typical 1. 5 volt AA alkaline cell or D cell battery,

Which raises an important question oe why isn't the potato battery already a roaring success?

companies or organisations embraced potato batteries?""The simple answer is they don't even know about it, Â reasons Rabinowitch.

The potatoes that don't make it to the market could easily be turned into batteries. Pithy answeryet in Sri lanka

and the best battery performance was obtained by chopping the plantain pith after boiling. With the boiled piths, they found they could power a single LED for more than 500 hours,

"In reality, the potato battery is essentially like a regular battery you'd buy at the store,

Basically, some people might not want to show off their potato battery to impress a neighbor. Still, it cannot be denied that the potato battery idea works,

and it appears cheap. Advocates of potato power will no doubt continue to keep chipping away.

In particular researchers have struggled to find an electrolyte which conducts ions between a battery's electrodes that won't break down

#Unzipped nanotubes unlock potential for batteriesresearchers at Rice university have come up with a new way to boost the efficiency of the ubiquitous lithium ion (LI) battery by employing ribbons of graphene that start as carbon nanotubes.

Proof-of-concept anodes--the part of the battery that stores lithium ions--built with graphene nanoribbons (GNRS)

After 50 charge-discharge cycles the test units retained a capacity that was still more than double that of the graphite currently used for LI battery anodes.

Better batteries are desired greatly by everyone who carries a cellphone or computer or drives an electric car.

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's 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 said. Graphene nanoribbons make a terrific framework that keeps the tin oxide nanoparticles dispersed

Lin said the lab plans to build batteries with other metallic nanoparticles to test their cycling and storage capacities.

#Super batteries? Hybrid ribbons a gift for powerful batterieshybrid ribbons of vanadium oxide (VO2) and graphene may accelerate the development of high-power lithium-ion batteries suitable for electric cars and other demanding applications.

The Rice university lab of materials scientist Pulickel Ajayan determined that the well-studied material is a superior cathode for batteries that could supply both high energy density and significant power density.

The research appears online this month in the American Chemical Society journal Nano Letters. The ribbons created at Rice are thousands of times thinner than a sheet of paper yet have potential that far outweighs current materials for their ability to charge

This is the direction battery research is going not only for something with high energy density but also high power density Ajayan said.

It's somewhere between a battery and a supercapacitor. The ribbons also have the advantage of using relatively abundant and cheap materials.

and in fact vanadium pentoxide has been used in lithium-ion batteries for its special structure and high capacity.

and lead author Shubin Yang said they believe that to be among the best overall performance ever seen for lithium-ion battery electrodes.

We think this is real progress in the development of cathode materials for high-power lithium-ion batteries Ajayan said suggesting the ribbons'ability to be dispersed in a solvent might make them suitable as a component in the paintable batteries developed in his lab.

obstacles to using silicon for a new generation of lithium-ion batteries say its inventors at Stanford university and the Department of energy's SLAC National Accelerator Laboratory.

and more powerful batteries for products like cell phones tablets and electric cars said Yi Cui an associate professor at Stanford

The anode or negative electrode is where energy is stored when a battery charges. Silicon anodes could store 10 times more charge than the graphite anodes in today's rechargeable lithium-ion batteries

but they also have major drawbacks: The brittle silicon swells and falls apart during battery charging

and it reacts with the battery's electrolyte to form gunk that coats the anode

and degrades its performance. Over the past eight years Cui's team has tackled the breakage problem by using silicon nanowires

when made in the thickness required for commercial battery performance. While these experiments show the technique works Cui said the team will have to solve two more problems to make it viable on a commercial scale:
