Eamex Extends Battery Life, Good News for Notebooks, Electric Cars

Paul Lilly

Do you know how often we hear about promising new battery technologies every year? Over 4 million times. That's what it feels like, anyway, even if we're way off in our estimation. But here's another number: One. That's how many battery breakthroughs we expect to materialize in an actual product in 2010.

The technology we're referring to comes from a Japanese company called Eamex, who says it has discovered a way to increase the life of high-capacity lithium-ion batteries. We tend to give this one a bit more credibility, if only because Eamex isn't talking about a theoretical tech that could eventually lead to the demise of lithium-ion.

What Eamex has done is figure out a way to stabilize the electrodes and prevent the deterioration of tin. Why's this important? Because it means the batteries can withstand a lot more charge and discharge cycles. We're talking about over 10,000 cycles with a shelf life of 20 years. By comparison, Apple says a MacBook or MacBook Pro battery can withstand about 1,000 cycles over about 5 years of constant use.

Unlike other battery technologies, you don't have to wait a decade for this one to come to market. Eamex says it will ship a battery with about 10,000W of power per kilogram (suitable for electric cars and scooters) by the end of 2010.
