Cathode active material slurry for solid electrolyte battery and cathode for solid electrolyte battery prepared therefrom

摘要

The present invention relates to positive electrode active material slurry for a solid electrolyte battery which comprises: a positive electrode active material; a conductive material; a solid electrolyte; an electrolyte sa and a dispersion medium dispersing the positive electrode material, the conductive material, the solid electrolyte, and the electrolyte salt. The present invention relates to positive electrode active material slurry for a solid electrolyte battery which further comprises a plasticizer dispersed by the dispersion medium and present in a solid phase at 15-25°C, wherein the plasticizer turns into a liquid phase and penetrates into a crack formed in the positive electrode active material when the plasticizer is exposed to a temperature environment above the melting point of the plasticizer, and to a positive electrode for a solid electrolyte battery manufactured therefrom.
