LITHIUM SECONDARY BATTERY AND METHOD FOR FABRICATING THE SAME |
摘要 |
An electrode group 4 in which a positive electrode plate 1 and a negative electrode plate 2, each having on a surface of a current collector a mixture layer containing an active material, are wound or layered, with a porous insulating layer 3 interposed between the positive electrode plate 1 and the negative electrode plate 2, is sealed in a battery case 5 together with an nonaqueous electrolyte. Metallic particles 12 melted from a negative electrode current collector 10 are dispersed throughout a negative electrode mixture layer of the negative electrode plate 2. The metallic particles 12 are a metal which is melted from the negative electrode current collector 10 and which is deposited in the negative electrode mixture layer by reverse charging a lithium secondary battery and subsequently charging the lithium secondary battery.
