Document Type and Number:
Japanese Patent JP2726285
Kind Code:
B2
Abstract:
PURPOSE:To improve the cell capacity and the self-discharge property by making an active substance with lithium or an alkaline metal including lithium as the main component, and a holding body with a composite material obtained by making an organic metal compound including a metal to alloy with an active substance react to a specific carbonaceous substance. CONSTITUTION:The active substance is lithium or an alkaline metal including lithium as the main component, and the active substance holding body has the atomic ratio of hydrogen/carbon less than 0.15; the surface interval of the 002 surface on the X-ray wide-angle diffraction method 3.37Angstrom or more; and the size of the crystalline in the c axis direction less than 150Angstrom . Under the condition an organic metal compound including a metal to alloy with an active substance is contacted to such a carbonaceous substance, a composite material of a carbonaceous substance obtained by pyrolyzing the organic metal compound and the metal to alloy with the active substance is used to form the cell. As a result, the charge and discharge cycle is extended, and the charge and discharge property under a large current is also improved.
