POSITIVE ELECTRODE FOR STACKED LITHIUM ION SECONDARY BATTERIES

摘要

Provided is a positive electrode for stacked lithium ion secondary batteries, which enables the production of a stacked lithium ion secondary battery having high long-term reliability. A positive electrode for stacked lithium ion secondary batteries, which is used for a stacked lithium ion secondary battery that is provided with a laminate obtained by laminating a plurality of positive electrodes and a plurality of negative electrodes respectively facing each other with separators and a nonaqueous electrolyte solution being interposed therebetween. The positive electrode is provided with a positive electrode active material layer containing positive electrode active material particles, and the ratio of the positive electrode active material particles having a crack among the positive electrode active material particles present in the outermost surface of the positive electrode active material layer is 20% or less.
