摘要： PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery which is improved in energy density by letting the positive electrode contain a nitroxide radical polymer as an anion scavenger. SOLUTION: The anion of the electrolyte supporting salt is captured by the anion scavenger, wherein the anion scavenger occludes anions of an electrolyte supporting salt contained in the positive electrode at the initial charge by the battery and does not discharge the occluded anions in the course of discharge by the battery. As a result, lithium ions are released from a positive electrode active material, while lithium ions are occluded in the negative electrode. Because of the presence of the anion scavenger contained in the positive electrode, the irreversible capacity of the negative electrode is compensated with the lithium ions in the electrolyte, which leads to the effective use of a lithium contained in the positive electrode active material.
