LITHIUM ION SECONDARY BATTERY

摘要

Disclosed is a lithium ion secondary battery comprising a positive electrode containing a lithium complex oxide, a negative electrode capable of charging/discharging lithium ions, a nonaqueous electrolyte solution, and a solid electrolyte layer interposed between the positive electrode and the negative electrode. The solid electrolyte layer contains solid electrolyte particles and a binder, and may further contain an inorganic oxide filler. For example, the solid electrolyte particles are composed of at least one material selected from the group consisting of LiCl-Li2O-P2O5, LiTi2(PO4)3-AlPO4, LiI-Li2S-SiS4, LiI-Li2S-B2S3, LiI-Li2S-P2O5 and Li3N.
