摘要:
In a secondary battery utilizing redox by a radical site, charge-discharge is carried out in such a manner that a lithium ion moves between a positive electrode and a negative electrode (rocking chair-type). An anion in an amount necessary for electrode doping during charge-discharge is made unnecessary, thereby reducing the amount of an electrolytic solution. A secondary battery with a large energy density is achieved. Provided is an electrode active material including at least one polymer including a radical site capable of being converted into a first cation, and an anion site capable of being bonded with the first cation or a second cation.
