Why is new energy vehicle made up of ternary lithium batteries?

Compared with lithium batteries, lead-acid batteries have much larger volume and weight than lead-acid batteries.

The assembly materials and external circuit systems of lead-acid batteries are extremely low in cost, so they are cheaper to use than lithium batteries.

Lead-acid batteries are usually deep-charged and discharged within 100 times. There are memories, and the life span is about one year. Lithium batteries are more durable, consume less, charge and discharge more than 5,000 times, and have no memories, usually lasting about 20 years. In terms of durability, the battery has good sensation resistance, and the battery in a completely charged state is safely fixed. It is sensible for 1 hour with an amplitude of 4 mm and a frequency of 16.7 Hz, no leakage, no battery swelling and break, and the open circuit voltage is normal; Overcharge, good control, open circuit voltage is normal, capacity retention rate is above 95%; high current resistance, no conduction, some fuse, no appearance deformation.

The lead acid has a short service life and large production pollution; the lithium battery is relatively greener in terms of production and recovery.

New energy vehicles are the direction of future car development and will definitely replace traditional energy vehicles. This is beyond doubt. But throughout the course of human civilization, when replacements appear, they are often met with skepticism rather than affirmation. The same is true for cars replacing horse-drawn carriages, or for new energy vehicles replacing traditional cars.
