Title:
NON-AQUEOUS ELECTROLYTE RECHARGEABLE BATTERY
Document Type and Number:
WIPO Patent Application WO/2012/014616
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a non-aqueous electrolyte rechargeable battery and a manufacturing method therefor etc., whereby the dispersion properties of a carbon conductive agent can be dramatically improved, and the battery characteristics can be dramatically improved due to the formation of a network with excellent conductivity. The non-aqueous electrolyte rechargeable battery is manufactured by: mixing a polyvinylpyrrolidone polymer and a polyglycerol-condensed ricinoleate ester as a dispersant in N-methyl-2-pyrrolidone as a dispersion medium, and then adding acetylene black thereto to prepare a carbon slurry; mixing a positive electrode active material with a binding agent in the carbon slurry to prepare a slurry of positive electrode active material; manufacturing a positive electrode (11) using the slurry of positive electrode active material; and then using the positive electrode (11).
