New Matsushita battery

Matsushita, the parent company of Panasonic, has developed a new lithium-ion battery with increased energy density, which the company claims can produce 20 to 40 percent more capacity. The secret is the material in the negative diode, which has been switched from graphite carbon to metal alloys. This boosts the capacity of an 18650-size battery from 2.9Ah to 3.6, and the energy density to 740Wh/L. The new batteries also have a heat resistance layer (HRL), preventing some of overheating problems caused by short-circuits in recent years. Matsushita 2.9Ah batteries with HRL have been on the market since April of 2006; the 3.6Ah design will arrive within the next couple of years. [Via DailyTech]
