Technology Description:

Recapping is developing a capacitor that could rival the energy storage potential and price of today's best EV batteries. When power is needed, the capacitor rapidly releases its stored energy, similar to lightning being discharged from a cloud. Capacitors are an ideal substitute for batteries if their energy storage capacity can be improved. Recapping is addressing storage capacity by experimenting with the material that separates the positive and negative electrodes of its capacitors. These separators could significantly improve the energy density of electrochemical devices.

Potential Impact:

If successful, Recapping's project would improve the energy storage in capacitors for use in EVs, making them competitive with existing EV battery technologies.

Security:

Cost-competitive capacitors with energy storage comparable to existing battery technology would enable the widespread use of EVs and renewable energy storage facilities. This would greatly reduce our dependence on foreign oil.

Environment:

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

Economy:

Diversifying our fuel supply for transportation and electricity production would help stabilize electricity rates for consumers and businesses.
