Abstract
The present invention pertains to a slurry composition for non aqueous electrolyte battery electrodes that includes a binder composition, an active material, and a solvent, in which the active material is a lithium-containing metal oxide, the binder composition contains a neutralized salt of an α-olefin-maleic acid copolymer in which an α-olefin and a maleic acid are copolymerized, and the degree of neutralization for carboxylic acid generated from the maleic acid in the copolymer is from 0.3 to 1.0. The present invention further pertains to a non aqueous electrolyte battery positive electrode and a non aqueous electrolyte battery using the slurry composition for non aqueous electrolyte battery electrodes.
