Title:
SOLID ELECTROLYTE SHEET AND ALL-SOLID TYPE LITHIUM SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2021034325
Kind Code:
A
Abstract:
To provide a solid electrolyte sheet which is superior in shape retainability and which can be arranged to have a large area, and an all-solid type lithium secondary battery which has the solid electrolyte sheet and which is superior in discharge characteristic.SOLUTION: A solid electrolyte sheet according to the present invention comprises: a support body composed of an insulating porous base material; and solid electrolyte particles and a binder in the insulating porous base material. The insulating porous base material is configured of (1) a resin fiber, and satisfies y/x≥0.45 where x(g/m2) is a basis weight and y(N) is a tensile strength, otherwise it is configured of (2) a liquid crystal polyester fiber. An all-solid type lithium secondary battery according to the invention comprises: a positive electrode; a negative electrode; and the solid electrolyte sheet of the invention inserted between the positive and negative electrodes.SELECTED DRAWING: Figure 2
