SLURRY FOR SECONDARY BATTERY POROUS MEMBRANE, SECONDARY BATTERY POROUS MEMBRANE, SECONDARY BATTERY ELECTRODE, SECONDARY BATTERY SEPARATOR, AND SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2012/046843
Kind Code:
A1
Abstract:
[Problem] To provide a secondary battery porous membrane which has high flexibility, contains little moisture content, and is produced by using a slurry for a secondary battery porous membrane, the slurry exerting excellent coatability and dispersibility of non-conductive organic particles, wherein it is possible to improve the cycle characteristic of the obtained secondary battery and to prevent powder from falling. To also provide a non-conductive organic particle which has a low content of metal foreign materials, and which can be suitably used for a secondary battery porous film. [Solution] The slurry for a secondary battery porous material of the present invention is characterized by containing: a binder comprising a polymerization unit of a vinyl monomer having a hydrophilic acid group; non-conductive organic particles having a functional group capable of cross-linking with the aforementioned hydrophilic acid group; and a solvent.
