Claim 0:
1. A battery, comprising:
a positive electrode, a negative electrode, and an electrolyte,
wherein the positive electrode includes a substituted barium titanate including barium strontium calcium lead titanate;
wherein the barium strontium calcium lead titanate is represented by a formula (1):

(Ba1-x-y-zPbxSryCaz)TiO3  (1)

wherein in the formula (1), x meets 0<x≤0.5, y meets 0<y≤0.2, and z meets 0<z≤0.2;
wherein the positive electrode further includes a positive electrode active material and a conductive agent, and
an average particle size of the substituted barium titanate is 20 nm or more and not more than an average particle size of the positive electrode active material;
wherein the positive electrode includes a positive electrode active material layer;
wherein the substituted barium titanate is provided in an entire of the positive electrode active material layer;
wherein an impedance ratio (Z2/Z1) between an impedance Z1 of the battery at 30° C. and an impedance Z2 of the battery at 150° C. is 4 or more.
