What are the advantages of lithium batteries compared to lead-acid batteries

1. Energy density: At present, the energy density of lead-acid batteries is about 5070wh/g, while the energy density of lithium batteries is generally 200260wh/g. In the case of the same battery weight, the discharge efficiency of lithium batteries is higher and the battery life is also better. Stronger. Judging from the current market performance, consumer demand for new energy vehicles with strong endurance is still relatively large, so lithium batteries have a full advantage in this regard. 2. Service life: Lithium battery has high safety and is still safe under harsh conditions such as acupuncture, short circuit, squeeze, etc., without deformation. The temperature performance is good, and the service life can not be affected under high temperature. Therefore, lithium batteries have a longer service life than lead-acid batteries. 3. Safety: a large amount of hydrogen and oxygen will appear when the lead-acid battery is charged for too long, and it will explode when it encounters an open flame. Most of the lead-acid batteries on the market currently have no overcharge protection, which means that once they are charged Excessively, it is very likely to be dangerous. In this regard, lithium batteries are relatively safer. 4. Impact on the environment: For a long time, the tower company's base station backup power supply has mainly used lead-acid batteries, and the annual purchase of lead-acid batteries is about 100,000 tons. Lead-acid batteries have short service life, low performance, and contain a large amount of heavy metal lead. If they are discarded, they will cause secondary pollution to the environment if they are improperly resolved. On the whole, although lead-acid batteries are not as good as lithium batteries in all aspects of performance, they are cheaper and more durable. However, at present, the development potential of lithium batteries is higher than that of lead-acid batteries. , As the power source of new energy vehicles is also very suitable.
