Lead-acid or lithium batteries for electric car batteries?

In recent years, with the large-scale use of lithium-ion batteries in two-wheel electric vehicles, explosions of lithium-ion batteries have occurred from time to time. This makes many people wonder whether it is really feasible to replace lead-acid batteries with lithium-ion batteries. Should electric vehicle batteries choose lithium-ion batteries or lead-acid batteries? Below, we look at the difference between lithium-ion batteries and lead-acid batteries in terms of mass and volume, service life, cost performance, and battery life. 1. Mass and volume Lead-acid batteries are larger and heavier. Compared with lithium-ion batteries, which are only 2.5/3 kilograms, lead-acid batteries generally weigh about 16/30 kilograms with the same capacity. Although the current lead-acid battery has begun to be lightweight, the lithium-ion battery can be flexibly disassembled and other methods, and its operability is better than that of the lead-acid battery. 2. Service life At present, the service life of lead-acid batteries is about 2 years, and the cycle charge and discharge is generally within 300 times; while the cycle charge and discharge of lithium ion batteries exceeds 500 times, the general life is more than 3 years, and lithium battery manufacturers have proposed 3 Yearly warranty. 3. Cost-effectiveness At present, the price of mainstream lead-acid batteries in the market is around 450 yuan, while lithium-ion batteries are relatively expensive. With the reduction of lithium-ion battery raw materials, some brands have also called out the price of lithium-ion lead-acid batteries. Fourth, the cruising range This is also the most concerned about electric vehicle users. The same 48V battery, when fully charged, the cruising range of lead-acid/lithium-ion battery electric vehicles is actually about the same, and the details depend on factors such as speed and motor size. Of course, in terms of battery capacity, lead-acid batteries will be slightly larger than lithium-ion batteries. In summary, users who are more sensitive to price and practicality can choose lead-acid batteries, and those who care more about battery operability can choose lithium-ion batteries with better performance. However, the safety of lithium-ion batteries needs to be addressed urgently! Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
