Title:
LITHIUM ION BATTERY AND ITS REGENERATION METHOD
Document Type and Number:
Japanese Patent JP2011146200
Kind Code:
A
Abstract:

To provide a lithium ion battery in which decomposition reaction of a film forming agent is suppressed.

The lithium ion battery 100 has electrodes 1, 2 and electrolyte solution housed in a battery container 13, and has a film forming agent addition means 20 which adds a film forming agent 21 for forming a film on the surface of the electrodes 1, 2 into the electrolyte solution in the battery container 13. By this film forming agent addition means 20, an electrochemical decomposition reaction of the film forming agent 21 is suppressed and a long-term preservation is enabled, and moreover, by adding the film forming agent 21 into the electrolyte solution, the film deteriorated on the surface of the electrodes 1, 2 is restored, and the lithium ion battery 100 is regenerated to attain a long life.
