Abstract: A battery is provided comprising a coated sintered cathode. The coated sintered cathode comprises at least one of lithium cobalt oxide (LiCoO2) or NMC (LiNi(1-x-y)MnxCoyO2). The coated sintered cathode also comprises a coating layer. The coating layer comprises at least one of aluminum oxide (Al2O3), aluminum fluoride (AlF3), zinc oxide (ZnO), magnesium oxide (MgO), titanium dioxide (TiO2), lanthanum oxide (La2O3), zirconium oxide (ZrO2), gallium oxide (Ga2O3), magnesium fluoride (MgF2), molybdenum trioxide (MoO3), selenium (Se), or phosphorous pentoxide (P2O5). The coating layer is coated on the sintered cathode by atomic layer deposition. The sintered cathode may form a cathode-electrolyte interface inside the battery, and the coating layer may be positioned at the cathode-electrolyte interface.
