One of the ongoing concerns with electric vehicles is the range: most can’t travel much more than 120 miles without needing to recharge. The idea that drivers will need to recharge their cars less than 150 miles from their home — rather than the fill ups that gasoline-powered cars require every 350 miles or so — has been a major concern for the average consumer.

Superlattice Power, a North Carolina-based battery company, has announced an innovation that may not get EVs up to a range of 350 miles, but can at least extend them to 200 miles. The company has developed a new lithium polymer battery that relies on a new type of superlattice cathode.

Hybrid Technologies has worked closely with Superlattice Power to develop their new battery and bring it a point of practicality for commercial use. Neither company is ready to put a new battery on the market, though, and it’s not clear when they will be ready to start sales. The two companies are specifically focusing on developing batteries for electric vehicles but have mentioned plans to adapt more efficient batteries for consumer electronics from iPods to laptops.
