Solid-State Lithium-Ion Battery With Ceramic Electrolyte
Technology Description:
The University of Maryland (UMD) is developing ceramic materials and processing methods to enable high-power, solid-state, lithium-ion batteries for use in EVs. Conventional lithium-ion batteries used in most EVs contain liquids that necessitate the use of heavy, protective components. By contrast, UMD’s technology uses no liquids and offers greater abuse tolerance and reducing weight. This reduced weight leads to improved EV efficiency for greater driving range. UMD’s technology also has the potential to help reduce manufacturing costs using scalable, ceramic fabrication techniques that does not require dry rooms or vacuum equipment.
Potential Impact:
If successful, UMD’s battery would offer extended battery life and low weight compared to conventional batteries, resulting in substantially improved driving range for EVs.
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.
