All Solid-State Lithium-Ion Battery
Technology Description:
Solid Power is developing a new low-cost, all-solid-state battery for EVs with greater energy storage capacity and a lighter, safer design compared to lithium-ion batteries. Conventional batteries are expensive, perform poorly at high temperatures and require heavy protective components to ensure safety. In contrast, Solid Power’s liquid-free cells store more energy for their size and weight, but use non-flammable and non-volatile materials that are stable high temperatures. This results in improved safety in the event of a collision or fire. Additionally, Solid Power plans to use low-cost, abundant materials in the range of $10-$20/kg that could reduce battery manufacturing costs, to help drive down the cost of EVs.
Potential Impact:
If successful, Solid Power’s solid-state battery would reduce battery costs and offer manufacturers greater flexibility with regard to battery placement and vehicle design.
Security:
The mass adoption of EVs would diminish the demand for petroleum, dramatically reducing U.S. dependence on foreign oil.
Environment:
Greater use of EVs would reduce U.S. greenhouse gas emissions, 28% of which come from the transportation sector.
Economy:
Technological advancements from the RANGE program could enable EVs to travel significantly further on a single charge at a much lower cost than that of current EVs and conventional vehicles.
