As the core part of electric vehicles, electric vehicle batteries are divided into many different types according to different raw materials. As an emerging new energy battery, lithium batteries are good and can be evaluated from the following aspects.
1. Durability.
Tianneng batteries can generally be charged and discharged within 400 times. They have memory and have a service life of about two years. Moreover, Tianneng batteries contain liquid. After the battery is consumed for a period of time, the liquid needs to be replenished. Lithium batteries are different. They are more durable than Tianneng batteries and consume very slowly. They can be deeply charged and discharged more than 500 times, and they are still the same. There is no memory, and the general lifespan is basically about 4 to 5 years.
2. Volume and quality.
Most Tianneng batteries are relatively large. The weight is generally 16-30 kg. On the contrary, the weight of lithium batteries is generally much lighter than that of Tianneng batteries, most of which are around 2.5-3 kg. And the size is small. It is easy to carry.
3. Manufacturing process.
When Tianneng batteries are manufactured, there is pollution during the production process. If they are not recycled properly, they may also cause pollution, which is a great harm to the environmental protection. Lithium batteries are relatively greener and more environmentally friendly.
Lithium metal batteries and lithium-ion batteries. Lithium metal batteries contain lithium in the metallic state and are generally not rechargeable. Lithium-ion batteries do not contain metallic lithium. They are rechargeable and were first used in pacemakers. The self-discharge rate of lithium batteries is very low and the discharge voltage is also very gentle, so that the pacemaker inserted into the human body can operate for a long time without having to recharge.
