With the development of lithium battery technology, will lead-acid batteries be eliminated?

With the development of lithium batteries, more and more people feel that it is no longer possible to make money by making lead-acid batteries. In reality, lead-acid batteries will still be a major trend in the next few decades. The reasons are as follows: 　　1. Lithium battery technology needs to be improved, and safety is low. Although lithium battery is a good development direction, there are still constructive breakthroughs in many aspects, such as safety and pass rate. In 2016, Samsung note7 battery explosion incident everyone should know, the lithium battery used in mobile phones is relatively simple, there is no series or parallel connection, the energy is only about 2wh, and its explosion rate has reached one millionth, while the energy of lithium batteries for electric vehicles is relatively high. Large, complex series structure, its safety is relatively low.　　Second, the production cost of lead-acid batteries is low, and the environmental pollution is low. 　　 Compared with lithium batteries, the production cost of lead-acid batteries is only about one-third, and the raw materials can be recycled and environmental pollution is relatively low.　　3. The lead-acid battery production process is mature and the equipment is simple. 　　 Lead-acid batteries have been developed for more than 150 years, with simple equipment and mature production processes. In recent years, batteries such as graphene and colloids have gradually developed, showing their longevity.　　From the above three points, it is not difficult to see that lead-acid batteries will inevitably have a life span of several decades, and lithium batteries still need innovative technology.
