How do lithium-ion batteries compare to lead-acid batteries

Compared with lead-acid batteries, lithium-ion batteries 1. In terms of safety in use, lead-acid batteries are safer. Lead-acid batteries are resistant to overcharge, so lead-acid batteries can be used directly, and lithium-ion batteries must be protected by a protective plate to ensure the battery. The main body will not be overcharged and overdischarged. In addition, the electrolyte of lithium-ion batteries is flammable, so relatively speaking, the risk of fire and explosion of lithium-ion batteries is higher than that of lead-acid batteries. From this perspective, lead-acid batteries are indeed better than lithium-ion batteries. 2. Compared with batteries, lithium-ion battery packs have natural advantages in environmental protection. The materials used in lithium-ion battery packs do not contain polluting metals such as cadmium, lead, mercury and other harmful heavy metal substances. There are no pollutants in the production and use of lithium-ion batteries, which protects human health and recycles waste batteries. The problem of polluting water and soil in the process is thus solved. 3. The energy density of lead-acid batteries is about 50-70wh/g, while the energy density of lithium-ion batteries is as high as 200260wh/g. In short, in the case of the same volume or mass, the energy storage of lithium-ion batteries is much higher than that of lead-acid batteries, and the discharge efficiency is also better. Lead-acid batteries in battery cars can be used for short-distance driving and are cost-effective, but when used in new energy vehicles, there are obvious shortcomings in battery life. 4. Sealing performance: The batteries of pure electric vehicles are generally placed on the chassis, and the battery is better sealed with lithium-ion batteries. In the usual wading section or pothole road, the impact resistance and waterproof ability of the battery directly affect the safety level of the vehicle, and the lithium-ion battery has reached the IP67 level. Lead-acid batteries and lithium-ion batteries have their own advantages. Although lithium-ion batteries have many advantages, at present, their technology is not perfect, and the initial products are often not mature. The lead-acid battery technology has become more mature and cheaper after years of precipitation. At present, it is relatively better. However, lithium battery is the future trend of the battery industry, and the technology is also being improved step by step. After improving the cost performance, I believe It can replace lead-acid batteries in the future. Although there are still some resistances in the development of the lithium-ion battery market, it is difficult to prevent batteries from exiting most markets as the industry reorganizes. In the future, the replacement of lead-acid batteries by lithium-ion batteries in some market areas will gradually accelerate, including electric bicycles and communications. Base stations and other fields are the most widely used, especially with the gradual promotion of new energy vehicles, and the further improvement of lithium-ion battery technology, the future market demand for power lithium-ion battery materials will be rapidly detonated.
