In this article, we are going to learn how a lithium-ion battery works.
The anode is made from carbon and stores all the lithium ions.
The cathode is made from metal oxides and it also stores the lithium.
The electrolyte carries the lithium ions from the one side to the other depending upon charging or discharging.
The separator blocks the flow of negative and positive molecules and only allows the flow of ions through them.
Advantages of Lithium-Ion cells
- Lithium-Ion batteries provide the same amount of power for much less weight i.e. it has higher power density than its counterparts.
- They provide a very good battery life. They lose about 5% of their battery life per month.
- They have a long cycle and also have long shelf lives. They can easily withstand hundreds of charging/discharging cycles.
- It has high efficiency and low internal resistance.
Disadvantages of Lithium-Ion cells
- Starts degrading at high temperatures and voltages.
- Regulations are applicable when shipping in large quantities.
- Requires protection against thermal runaway if stressed too much.
Applications of Lithium-Ion cells
- Lithium Ion batteries have a wide variety of applications. Some of them are listed below:
Lithium-ion cells are rechargeable batteries that are widely used in a variety of applications due to their high energy density, long cycle life, and low self-discharge rate. Here are some common applications of lithium-ion cells:
