POSITIVE ELECTRODE FOR SECONDARY BATTERY, SECONDARY BATTERY, AND METHOD OF RECYCLING POSITIVE ELECTRODE FOR SECONDARY BATTERY

A positive electrode for the secondary battery includes a positive electrode active material layer and a positive electrode current collector. The positive electrode active material layer includes a positive electrode active material and a polymer compound. The positive electrode current collector supports the positive electrode active material layer. The positive electrode active material includes a lithium-transition-metal compound. A thermogravimetric loss rate measurable when the polymer compound is fired until a temperature of the polymer compound becomes 400° C. in atmospheric air is 60% or higher.
