| Explanation |
Anode:- Graphite electrode gets oxidised when the load is connected and free lithium ion and electron released. Free electrons move in the direction opposite to the current direction and free lithium ion moves towards the cathode. Cathode:- when the load is connected, the current moves out from the cathode made up of Lithium cobalt oxide (LiCoO2) and the reduction process started. Free lithium ion gets attached to the cathode. |
