Invention Reference Number
The co-processing of cathode and composite electrolyte for solid state polymer batteries has been developed. A traditional uncalendared cathode of e.g. NMC622 active material is used as a support on top of which the particles of ceramic electrolyte are deposited via either tape casting or spray coating. Subsequent flash sintering using intense pulse light improves connectivity among the ceramic electrolyte particles which results in better ion transport through the ceramics. The structure is then infiltrated with the polymer electrolyte which fills the pores in the cathode and in the ceramic electrolyte layer. The resulting cathode/composite electrolyte stack is then integrated into the battery cell.
