What is battery discharge

- Sep 20, 2019-

The lithium battery is discharged, Li+ is deintercalated from the negative electrode, and the electrolyte is embedded in the positive electrode, and the positive electrode is in a lithium-rich state, that is, the battery is discharged when it is normally used, and the opposite is charged.


When the battery is discharged (ie, the process we use the battery), the lithium ions embedded in the carbon layer of the negative electrode come off and move back to the positive electrode. The more lithium ions return to the positive electrode, the higher the discharge capacity.
