Title:
POSITIVE ELECTRODE ACTIVE MATERIAL FOR NON-AQUEOUS ELECTROLYTE SECONDARY CELL, NON-AQUEOUS ELECTROLYTE SECONDARY CELL, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2017/104630
Kind Code:
A1
Abstract:
Although carbon materials of plant origin can be used for a negative electrode active material of a non-aqueous electrolyte secondary cell, it has not been possible to use such materials for a positive electrode active material in which a higher potential is needed than in a negative electrode. In this invention, a carbonized plant material, particularly a carbonized cotton material, containing a graphite component is used as a positive electrode active material for a non-aqueous electrolyte secondary cell. Carbon materials of plant origin are reproducible unlike carbon materials obtained from fossil fuel resources, and measures to utilize carbon materials of plant origin are desirable from the viewpoint of preserving and improving Earth's environment.
