MIT Creates Super Battery
Imagine charging your self phone in seconds instead of hours. Professor Gerbrand Ceder from MIT has devised a new lithium-ion battery electrode that is many times faster than its predecessors. While most discharge at a rate of a minute and a half with the best high powered batteries, this one works in only 10 to 20 seconds. That rate will allow a 1 liter battery to deliver about 25,000W, enough power for about 20 vacuum cleaners. Ceder and his team modified lithium iron phosphate, an electrode material, so that electrons and ions could move more quickly.
Current lithium rechargeable batteries can store large amounts of energy but don’t have the acceleration speed. Professor Cedar claims that because the material is not new, but simply remade, scientists could conceivably market it in the next couple of years.
