Title:
POSITIVE ELECTRODE MIXTURE SLURRY AND ELECTRODE SHEET
Document Type and Number:
Japanese Patent JP2013254620
Kind Code:
A
Abstract:

To provide a positive electrode mixture slurry which is excellent in coating property and adhesion, and with which a lithium ion battery having high energy density can be manufactured.

A positive electrode mixture slurry includes: a positive electrode material including an active material and a conductive material having pores, the active material existing at least one of on a surface of the conductive material and in the pore; a solid electrolyte including lithium and sulfur; a binder which is a resin including a structural unit represented by the following formula (I) in a molecular skeleton thereof; and a solvent in which a part or the entire of the binder is dissolved (in the formula, at least one of R1-R4 represents a fluorine atom, -CF3, -CH2CF3, -CF2CF3, -CF2CF2CF3, -OCF2CF2CF3 or -OCF3).
