Heard this on the local radio the other day. Washinton State University has developed a technology that triples the capacity of the lithium ion battery, reduces cost and makes it faster charging. It sounds promising, especially the part about bringing it to market in a year. If they succeed, it could totally change the market for electric cars. I would definitely buy a 300 mile range electric. This technology would be great for cell phones, tablets & laptops too.
