National labs leading charge on building better batteries
Date:9/27/2011

new anode made from a tailored polymer a material made of millions of repeating units that conducts electricity. It also embeds silicon particles, which in turn bind to a lot of lithium ions (much more than graphite anodes can). These improvements give the battery a much greater capacity the ability to store much more energy than current designs. Even better, they maintain that increased capacity after hundreds of charge-discharge cycles.

The better anode built by Berkeley Lab could contribute to lowering the cost and extending the range of electric cars. Researchers say the anode can be built at a comparatively low cost, and in a way that's already compatible with established manufacturing technologies. And they offer that the tailored polymer that makes the battery better could see use in a wide range of other products too.

Thanks to the Energy Department-supported research, bright ideas are becoming better batteries... and hopefully, a brilliant future.
