Abstract
Official abstract text for this publication.
There are provided a battery electrode wherein an active material layer is formed on a collector surface, and the layer contains an active material and a block copolymer having a vinyl alcohol polymer block; and a lithium ion secondary battery having a laminate structure in which a pair of electrodes having an active material layer are disposed in such a manner that the active material layers face each other via a separator, and an electrolyte composition containing a lithium-containing electrolyte salt fills the gaps between the pair of electrodes and the separator, wherein at least one of the pair of electrodes is the above battery electrode. Thus, there can be provided a lithium ion secondary battery which can be easily produced and be less polarized, exhibiting excellent charge/discharge properties and cycle characteristics.
First claim
Opening claim text (preview).
The invention claimed is: 1. A battery electrode, comprising: an active material layer, wherein the active material layer is formed on a collector surface, and the active material layer comprises an active material and a block copolymer having a vinyl alcohol polymer block wherein said vinyl alcohol polymer block is produced by saponifying a vinyl ester polymer and has a saponification degree of from 75 to 99.95 mol %. 2. The battery electrode according t…
