I was excited by news that some companies, notably Zap&Go in the UK, and StoreDot in Israel, are making some progress with faster-charging and more stable alternatives to the lithium-ion batteries which are generally used today in electric cars.
Zap&Go is pursuing nanocarbon-ion batteries in partnership with a Chinese battery producer, and is holding out the prospect of a full charge in as little as 5 minutes (about as long as it currently takes to fill up with gas). StoreDot also makes use of nano-materials and proprietary organic compounds, and is also talking about 5 minute charges.
Neither company is quite there yet, but the prospects are bright, and they could revolutionize the already-burgeoning interest in electric vehicles.
