MIT discovery could “supercharge” lithium ion batteries

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, […]
