A team of engineers from Northwestern University has created an electrode for lithium-ion batteries that allows the batteries to hold a charge up to 10 times greater than current technology. Batteries with the new electrode also can charge 10 times faster than current batteries. The researchers used a graphene-silicon sandwich.
This blog is focused on trends in battery technology and other types of energy storage that are used for smart grid load leveling and stabilization, and as back-up power for renewable energy sources such as photovoltaics/solar power, hydro and wind energy. Trends in lithium ion batteries, lead-acid, metal-air, NaS (sodium sulfur), ZnBr (zinc-bromine) batteries will be covered, as well as compressed air energy storage (CAES), flywheels, fuel cells and supercapacitors.

"Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium-ion batteries on the market today."ReplyDelete
If they can pull this off it solves the EV battery problem. A 10x improvement in capacity means that we could have 200 mile range EVs with batteries only 1/5th size/weight/cost of today's batteries.
Faster charging would mean that no one would need more than about 200 miles range. Drive/charge/drive/charge/drive and you've done a 500+ mile driving day with only two short stops.
