Abstract: A high-temperature bipolar battery consisting of a plurality of stacked individual cells. A first, thermal-sprayed electrode or electrolyte resistant material ceramic layer is sprayed to the exterior of the face-to-face stacked array and onto the peripheral faces of the battery metal end plates remote from the individual cells of a thickness sufficient to virtually eliminate all through pores therein. A second thermal-sprayed ceramic layer is of a thickness sufficient to form a metal support and containment structure of the bipolar battery stack. The thermal-sprayed layers have similar coefficients of thermal expansion (CTE). A metal cup surrounds and encloses at least one of the electrodes of each individual cell tending to form an inter-cell seal between the thermal-sprayed ceramic layer and the metal cup to prevent communication of electrolyte from cell to cell. Preferably the cups and any screens between the electrolyte layer and the anodes and cathodes of the respective cells extend radially beyond the electrodes and are embedded in the thermal-sprayed ceramic layer. The thermal-sprayed ceramic layer may be MgO of 20 mil. thickness and the thermal-sprayed metal layer may be 410 stainless steel of 50 mil. thickness.

Abstract: Pre-lithiation methods using lithium vanadium fluorophosphate (e.g., LiVPO4F and its derivatives) (“LVPF”) as a cathode active material in a lithium-ion secondary battery. The pre-lithiation methods include compensating for an expected loss of active lithium by selecting LVPF having a specific pre-lithiated chemistry (or a blend of LVPF selected to have a specific pre-lithiated chemistry) and selecting a total amount of the pre-lithiated LVPF. The pre-lithiation methods may include initially charging the lithium-ion secondary battery at the lower of the two charge/discharge plateaus of LVPF to release active lithium.
