Project Innovation + Advantages:

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 ionicelectronic conducting (MIEC) ceramics and processing techniques to fabricate thinner, higher porosity, and thus lower mass (porous/dense) “bilayers” and (porous/dense/porous) “trilayers.” The patented 3D ceramic architecture has shown the highest Li-metal cycling rate for solid-state technology (10 milliampere/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 architectures that enable higher gravimetric and volumetric energy densities and integrate cobalt/nickel-free, high-voltage cathodes with advanced, nonflammable electrolytes.
