Document Type and Number:
Japanese Patent JP6252858
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide: a positive electrode for lithium ion secondary batteries which high in capacity and safety; and a lithium ion secondary battery.SOLUTION: A positive electrode for lithium ion secondary batteries comprises: a current collector made of stainless steel; and a positive electrode active material layer bound to the current collector. The positive electrode active material layer includes: a first positive electrode active material; a second positive electrode active material; and a binding agent. The first positive electrode active material is a lithium-containing oxide expressed by the following general formula: LiNiCoMnDO(where 0.2≤a≤1.7; b+c+d+e=1; 0≤b<1; 0≤c<1; 0≤d<1; 0≤e<1; D is at least one element selected from Li, Cr, Cu, Zn, Ca, Mg, Zr, S, Si, Na, K and Al; 1.7≤f≤2.1). The second positive electrode active material is a lithium iron-containing oxide expressed by the following general formula: LiFeMPOF(where M is at least one element selected from Mn, Co, Ni, Cu, Mg, Zn, V, Ca, Sr, Ba, Ti, Al, Si, B, Te and Mo; 1≤g≤2; 0≤h<1; 0≤i<1).
