NEGATIVE ELECTRODE FOR LITHIUM BATTERY, AND LITHIUM BATTERY |
摘要 |
PROBLEM TO BE SOLVED: To prevent swelling of a battery due to the generated gas when storing a lithium battery using a carbon material for a negative electrode in the condition that the lithium battery is discharged. SOLUTION: In the lithium battery housing a positive electrode 12, the negative electrode 123 and a non-aqueous electrolyte in a battery container 10, the carbon material for storing and discharging lithium and an additional material composed of an element having a lithium emitting mean potential higher than that of the carbon material are mixed for the negative electrode, and the additional material is added to the carbon material in a range of 0.01-9.0 wt.%. The carbon material and the additional material having a mean granular diameter in a range of 0.01-5 μm are used. |
