A lithium secondary battery and a manufacturing method for the same

Document Type and Number:

Japanese Patent JP6032504

Kind Code:

B2

Abstract:

This invention provides a lithium secondary battery capable of bringing about greater cycle characteristics, being in a 4.2 V or higher class. The lithium secondary battery provided by this invention is a 4.2 V or higher class lithium secondary battery using a lithium transition metal composite oxide as a positive electrode active material. The lithium secondary battery comprises a negative electrode at or around which a silicon-containing cyclic compound and/or a reaction product thereof are present. The silicon-containing cyclic compound comprises at least one silicon atom in its ring and has a vinyl group.
