Abstract
(EN)
The purpose of the present invention is to provide a dual ion battery excellent in high-temperature durability. The dual ion battery of the present invention has a positive electrode including a positive electrode current collector and a positive electrode active material disposed thereon, and a negative electrode including a negative electrode current collector and a negative electrode active material disposed thereon. The positive electrode active material includes graphite. The negative electrode active material includes a metal oxide capable of occluding and releasing cations. The positive electrode current collector and the negative electrode current collector are made of an aluminum material covered with an amorphous carbon film.
