Technology Description:

The University of Maryland (UMD) will increase the charge/discharge-rate capability, energy density, and operating temperature window of solid-state lithium metal batteries. The team will use new mixed ionic-electronic conducting (MIEC) ceramics and processing techniques to fabricate thinner, higher porosity, and thus lower mass, (porous/dense) “bi-layers” and (porous/dense/porous) “tri-layers.” The patented 3D ceramic architecture has shown the highest Li-metal cycling rate for solid-state technology (10 mA/cm2) and demonstrated multiple high-energy-density (~300Wh/kg) cells with multiple cathode chemistries and cell configurations. UMD will integrate the MIEC ceramics in new advanced cell architectures that enable higher gravimetric and volumetric energy densities and integrate cobalt/nickel-free, high-voltage cathodes with advanced, nonflammable electrolytes.

Potential Impact:

EVs4ALL’s primary objective is to increase the domestic adoption of new and used EVs by enabling safe, resilient, fast-charging batteries with improved performance at low temperatures.

Security:

Solutions will target the use of “noncritical” battery materials, while minimizing the use of cobalt and nickel. A reduced dependence on the importation of critical metals supports U.S. energy independence.

Environment:

80% adoption of EVs in the U.S. could reduce overall CO2 emissions by 800 million tons/year.

Economy:

80% adoption of EVs in the U.S. could reduce annual energy consumption by 4 quadrillion British Thermal Units.
