Technology Description:

Stanford University is developing an all-electron battery that would create a completely new class of energy storage devices for EVs. Stanford’s all-electron battery stores energy by moving electrons rather than ions. Electrons are lighter and faster than the ion charge carriers in conventional Li-Ion batteries. Stanford’s all-electron battery also uses an advanced structural design that separates critical battery functions, which increases both the life of the battery and the amount of energy it can store. The battery could be charged 1000s of times without showing a significant drop in performance.

Potential Impact:

If successful, Stanford would create an entirely new class of EV batteries capable of storing much more energy than traditional Li-Ion batteries, facilitating widespread EV use.

Security:

Increased use of EVs would decrease U.S. dependence on foreign oil—the transportation sector is the dominant source of this dependence.

Environment:

Greater use of EVs would reduce greenhouse gas emissions, 28% of which come from the U.S. transportation sector.

Economy:

This project would help position the U.S. as a leader in rechargeable battery manufacturing. Currently, the U.S. manufactures only a small percentage of all rechargeable batteries, despite inventing the majority of battery technologies.
