A battery is proposed that utilizes a Li+ conducting, solid-electrolyte separator, LiSICON, Li metal anode and high-capacity cathode. The LiSICON ceramic is fabricated using state of the art tape casting methods which allows composite structures of porous and dense layers ~100ƒÝm thick. The layered structure increase mechanical strength and decrease interfacial and bulk resistances. The high-energy cathode material, amorphous MnO2 or nano-crystalline LiMn1/3Ni1/3Co1/3O2, allow a predicted energy density >400 Whr/kg for the overall battery. The proposed Phase II effort expands on the successful demonstration of small-scale cells utilizing both cathode materials in Phase I. The Phase II Base objectives are improving cathode performance and lowering cost, fabricating and validating the pressure tolerant casing, selecting anodes, electrolytes and fabricating a thin LiSICON ceramic electrolyte separator.
