Harvard Invents a Solid-State Battery.

Solid-state batteries are a promising technology, although technical problems must be solved before they can be manufactured at an industrial scale. A new type of solid-state battery pioneered by Adden Energy points to a leap in performance and reliability.

The startup uses an exclusive technology license from Harvard's Office of Technology Development to develop solid-state battery systems for use in future electric vehicles. On the basis of lithium-metal technology, the battery can achieve charge rates as fast as three minutes with over 10,000 cycles in a lifetime. The coin-cell prototypes developed by Adden Energy for lab testing don't look like much now. Still, Adden wants to scale the battery up to a palm-sized pouch cell and even to a full-scale electric vehicle battery.

The results are well above those for other Li-lon battery projects, and Adden Energy is confident it can have commercial samples in the next three to five years.
