The working principle of lithium ion battery

- Jan 17, 2018-

The cathode material of lithium ion battery is cobalt oxide, the cathode is carbon. When charging the battery, lithium ions are generated on the positive electrode of the battery, raw tea lithium ions through the electrolyte movement to the negative, and as the negative carbon is layered structure, it has a lot of micro-pores, to reach the anode lithium ions embedded in the carbon layer of the micro-pores, the more embedded lithium ions, the higher the charging capacity.

Similarly, when the battery is discharged (that is, the process of using the battery), embedded in the negative carbon layer of lithium ions, there is movement back to the positive, back to the positive electrode more lithium ions, discharge capacity, we usually say the battery capacity refers to the discharge capacity.
