LITHIUM ION BATTERY SYSTEM AND CHARGE-DISCHARGE CHARACTERISTIC ADJUSTMENT METHOD THEREFOR

摘要

To solve the following problem: when a service temperature of a lithium ion battery 1 changes, its charge-discharge characteristics degrade.SOLUTION: A lithium ion battery 1 uses an electrolyte solution formed by dissolving two or more types of lithium salts in a solvent as a supporting electrolyte, detects a service temperature of the lithium ion battery 1, and changes an air-fuel ratio of the two or more types of electrolytes in the electrolyte solution according to the service temperature.SELECTED DRAWING: Figure 1
