Title:
リチウム二次電池の製造方法およびリチウム二次電池
Document Type and Number:
Japanese Patent JP4602478
Kind Code:
B2
Abstract:
A negative electrode active material layer 3 containing at least one element selected from the group consisting of silicon, germanium, and tin is formed on a negative electrode collector 1. A negative electrode 11 is prepared by forming a lithium metal layer on the negative electrode active material layer 3. Also prepared is a positive electrode 11 having a configuration in which a positive electrode active material layer 6 containing a composite oxide represented by a general formula Li1-xMO2, where 0.2@x@0.6, and M includes at least one transition metal selected from the group consisting of cobalt, nickel, and manganese, is formed on a positive electrode current collector 5. A lithium secondary battery 100 is assembled from the negative electrode 13, the positive electrode 11, and a separator 4.
