Electrode Material for Non-Aqueous Electrolyte Secondary Battery, and Electrode for Non-Aqueous Electrolyte Secondary Battery and Non-Aqueous Electrolyte Secondary Battery Using the Same

摘要

A core-shell-type electrode material is used as an electrode active material layer of a non-aqueous electrolyte secondary battery, the core-shell-type electrode material having a core part including an electrode active material and a shell part in which a conductive material is contained in a base material formed by a gel-forming polymer having a tensile elongation at break of 10% or more in a gel state.

主权项

1. An electrode material for a non-aqueous electrolyte secondary battery used for a non-aqueous electrolyte secondary battery using a liquid electrolyte, a gel polymer electrolyte, or an ionic liquid electrolyte, the electrode material comprising:
a core part including an electrode active material; and a shell part in which a conductive material is included in a base material formed by a gel-forming polymer having a tensile elongation at break of 10% or more in a gel state, the gel-forming polymer being a polyurethane resin which is obtained by reaction of a polyisocyanate compound with polyether polyols, polyester polyols, polyester polycarbonate polyols, crystalline or noncrystalline polycarbonate polyols, polybutadiene polyol, or silicone polyol.
