SECONDARY BATTERY

摘要

PURPOSE:To enable stable high-capacity discharge by using lithium or alkarine metal chiefly containing lithium as active material and forming a carrier from mixture of specific carbon material and metal able to be alloyed with the active material. CONSTITUTION:Active material is lithium or alkaline metal chiefly containing it and a carrier is formed from mixture of both a carbon material having the face-to-face spacing (d002 between face (002) of 3.37A or more by the X-ray wide-angle diffraction method and the crystal element in the (c) direction of 150A or less in size, and metal able to be alloyed with active material. so the mixture material thermally discomposes organic compound into carbon and simultaneously thermal discomposes the organic metal compound containing metal able to be alloyed with the active material. Since lithium(Li) which functions as active material at the time of charging or alkaline metal chiefly containing lithium may be fixed stable to the carrier, the high capacity current may be discharged stably.
