Lithium batteries will replace lead-acid batteries?

The mainstream of electric vehicles on the market is divided into lead-acid batteries and lithium batteries. From the perspective of the market share, lead-acid batteries are far higher than lithium batteries. To find out the truth, lead-acid batteries are cheaper and cheaper. Lithium-ion batteries are relatively expensive compared to lead-acid batteries, but slowly we will find that lead-acid batteries have many shortcomings, and they are not as polluting as lithium batteries at the same time. Therefore, lead-acid batteries will be replaced by lithium batteries in the future.

In an interview with reporters, Mou wenquan, executive deputy director of the Shanghai New Energy Vehicle Inspection Engineering Technology Research Center, said that upgrading lithium power is very necessary and reasonable, both from the national strategic level and from the aspects of technology upgrading, economy, and safety of products. From the perspective of technology upgrade, lithium batteries have advantages such as higher energy, long service life, and environmental protection. With the further development of the battery industry, it is bound to replace lead-acid batteries. This is the development trend of the industry. Economically, lithium-ion batteries have a longer life cycle and average operating costs are not much higher than lead-acid batteries. The selection of lead-acid batteries is mainly influenced by the psychological factors that consumers are saving their purchase costs; In terms of safety, lithium batteries are lighter in relative weight, safer in the event of an impact, and improve the safety of the product.

In addition, due to the relatively high cost of lithium batteries, manufacturers may prefer to use low-cost lithium batteries to reduce costs. Mou wenquan said that in order to prevent manufacturers from choosing cheap batteries, it is necessary to set standards for the use of lithium batteries. For products that have been produced but have not yet been sold, Mou wenquan said. "According to reason, these products are not up to standard, they are not identified, and they should be completely banned, but considering the reality, giving a certain period of time the transition period can be considered. "

"Lithium batteries are facing overcapacity problems this year. It is stipulated that the use of lithium batteries in low-speed electric vehicles is also a way to digest lithium batteries and ensure the stability of the lithium battery market." For the lead-acid battery industry, it has been said that the lead-acid battery consumption tax is crushed. The last straw of the camel, the low-speed electric vehicle market is now split, and lead-acid battery companies will face a more severe market situation. Tianneng, Chaowei and other lead-acid battery giants are also actively developing and producing lithium batteries, seeking transformation and upgrading.
