Title:
リチウムイオン二次電池用電極、およびリチウムイオン二次電池
Document Type and Number:
Japanese Patent JP7397965
Kind Code:
B2
Abstract:
Provided are: an electrode for a lithium-ion secondary battery, said electrode enabling a battery having a high volumetric energy density to be attained, without reducing heat stability, even if a positive electrode active material that contains a high percentage of Ni is used; and a lithium-ion secondary battery that uses the positive electrode. An electrolyte and highly-dielectric solid particles are present in an electrode mixture layer at a specific volume ratio. Specifically, the electrode for a lithium-ion battery is configured such that the electrode mixture layer includes an electrode active material, a highly-dielectric solid oxide, and an electrolyte, wherein the volume ratio of the electrolyte and the highly-dielectric solid oxide in the electrode mixture layer is set in the range of 99:1 to 76:24.
