Abstract
Official abstract text for this publication.
Disclosed is a non-aqueous electrolyte secondary battery using a polyanion compound or a lithium nickelate as a positive electrode active material, suppressing the elution of a transition metal from the polyanion compound or ameliorating the deterioration of a binder by a residual alkali component, and provides a non-aqueous electrolyte secondary battery having a negative electrode intercalating and deintercalating lithium ions, a positive electrode containing a lithium-containing compound as a positive electrode active material, and a non-aqueous electrolyte with a lithium salt dissolved in organic solvent. The lithium-containing compound is a polyanion compound or a lithium nickelate. The non-aqueous electrolyte contains a fluorosilane compound: R 1 to R 3 : alkyl group having 1-8 carbon(s), an alkenyl group having 2-8 carbons, a cycloalkyl group having 5-8 carbons, an aryl group having 6-8 carbons or a fluorine atom. R 4 : alkylene group having 1-8 carbon(s) or an alkylene group having 4-8 carbons having an ether group.
First claim
Opening claim text (preview).
The invention claimed is: 1. A non-aqueous electrolyte secondary battery having a negative electrode that is capable of intercalating and deintercalating lithium ions, a positive electrode containing a lithium-containing compound as a positive electrode active material, and a non-aqueous electrolyte in which a lithium salt is dissolved in an organic solvent, wherein the lithium-containing compound is a polyanion compound or a lithium nickelate, and the non-aqueous electrolyte cont…
