Abstract
A polymer battery which comprises a negative electrode comprising a carbon material as an active material, an electrolyte layer and a positive electrode comprising a chalcogenide containing lithium as an active material, characterized in that the electrolyte layer comprises an ion-conducting compound and a polymer fiber, and the carbon material comprises the graphite particles having amorphous carbon adhered on the surface thereof. The polymer battery is capable of preventing the decomposition of the ion-conductive material by graphite particles.
