One of the big problems with existing battery technologies is the charge and discharge rate. A battery that powers a device for several hours can take nearly the same amount of time to recharge, making it difficult to develop “continuous use” devices. There has been a lot of research into new technologies like super-capacitors, but production use of these approaches is years if not decades in the future. Thanks to the folks at MIT, however, we may soon have a simple alternative: quick-charge (and discharge) Lithium Ion batteries.
