New Rechargeable Battery Lasts for 20 Years!

There’s nothing more depressing for a gadget guru than to pick up favourite camera or media player etc… and have it lay dead in the palm of his hand. Diagnosis? A dead battery. Bummer.

It’s really been a given for the past century. Batteries waste. Sure the Duracell bunnies would have us believe otherwise but they do. Even rechargeable batteries which can be found in everything from cameras to electric scooters can die due to being worn out. However, that’s all about to change. A new type of lithium-ion rechargeable battery has been introduced which is said to last over twenty years (around 10,000 charges). Now that’s value for money.

A Japanese company by the name of Eamex have cured the cause (<– link requires a subscription to read) of batteries burning out. With normal rechargeable batteries, the negative electrode deteriorates over use. This new design aims to coat the negative terminal in a special protective film (tin coated resin) which will protect it. This will last a regular user over twenty years.

So in theory, you could have five or six digital cameras but only one pair of batteries! Pretty cool. Expect to see these new batteries later this year.
