リチウム電池用固体電解質シート、その製造方法、及びそれを用いた全固体二次電池

摘要

PROBLEM TO BE SOLVED: To provide a solid electrolyte sheet and an electrode sheet having a large area in which ion conductivity is hardly reduced even if a support is introduced for making a sheet self-supported.SOLUTION: A solid electrolyte sheet comprises a solid electrolyte and a support having a plurality of openings, in which the solid electrolyte has a continuous through-structure in a thickness direction in the openings of the support, the support is composed of glass, and opening ratio of the support is 40 to 90%.
