Typically, the sintering temperature of solid electrolytes can reach as high as 700℃ - 1000℃ by conventional sintering processes [1].Impurity phases were detected at the interface between solid electrolyte and electrode after the high-temperature sintering process, which are capable of blocking the transportation of lithium ions during electrochemical cycling [25]. Thus, the CSP of active materials and solid electrolytes could be a promising route in solving this issue.
