Lithium-Ion Batteries: The Heart of Electric Cars
Lithium-ion batteries are the most common type of rechargeable battery used in electric vehicles. They consist of three primary components: positive electrodes (cathodes), negative electrodes (anodes), and an electrolyte solution. The cathode is typically made of lithium cobalt oxide, while the anode is made of graphite. The electrolyte is a lithium salt dissolved in an organic solvent.
The Benefits of Lithium-Ion Batteries
Lithium-ion batteries offer several advantages that make them ideal for electric vehicles:
- High energy density: Lithium-ion batteries pack a lot of energy relative to their size and weight.
- Long cycle life: They can be charged and discharged hundreds of times without losing their capacity.
- Low self-discharge: Lithium-ion batteries lose their charge relatively slowly, making them suitable for long-term storage.
- High discharge rate: They can supply a high current, making them suitable for applications that require rapid energy release.
How Many Lithium Batteries Are in an Electric Car?
