Why lithium batteries have not replaced lead-acid batteries for a long time

With the rapid development of the lithium battery industry in recent years and the continuous deepening of environmental protection concepts, a revolution in replacing lead-acid batteries with lithium batteries has been initiated, especially after the promulgation of the new national standard for electric vehicles. Many people have overestimated the replacement of lithium batteries. The market structure of lead-acid batteries, but as this craze fades, more and more people return to rationality. Why can't lithium batteries replace lead-acid batteries for a long time? In addition to market behavior, there are problems with lithium batteries and knowledge of lithium batteries. There are also certain reasons why the popularity has not kept up. Lithium batteries are different from lead-acid batteries because they have a higher energy density, but they also require the production process and technical capabilities of lithium batteries to be comparable to non-lead-acid batteries. Many manufacturers have been involved in the production of lithium batteries. Due to their limited technical capabilities, Although efforts have been made to lower the price, the lowering of quality standards has caused the quality of lithium batteries on the market to be uneven for a period of time. Generally speaking, the safety factor of products produced by big-brand lithium battery manufacturers is relatively higher, but the price will be higher. On the contrary, although the products of small manufacturers are cheaper, this is the result of sacrificing the safety factor. Many lithium battery accidents are caused by poor production quality and technology. In addition, the frequent fire accidents of the large company Tesla inevitably give rise to new thinking about the safety of lithium batteries. Compared with lead-acid batteries, the advantages of lithium batteries are quite obvious. A few years ago, some people said that lead-acid batteries would be replaced by lithium batteries. However, after many years, lead-acid batteries are still the mainstream in the market. So where are the main obstacles to the replacement of lead-acid batteries by lithium batteries? First, the cost-effective advantage of lithium batteries is not outstanding. In actual use, although lithium batteries have a longer battery life, they also have a higher price. Compared with lithium batteries and lead-acid batteries of capacity, lithium batteries are more expensive than lead-acid batteries. In addition, if the lead-acid battery is used normally after replacement, there will be no problems until the end of life. However, if the lithium battery is handled slightly incorrectly, it is very likely that problems will occur soon. Second, the long repair time severely restricts the use of consumers. Once the lithium battery fails to be repaired, it takes about a week or even longer, which makes consumers wait impatient and lose their confidence in using it. The reason is that the dealers cannot repair or replace the battery cells with problems inside the lithium battery. They must be delivered to the manufacturing company by express delivery, and the battery should be repaired through professional equipment. This is one of the keys restricting the large-scale replacement of lead-acid batteries by lithium batteries. Thirdly, lithium batteries are too 'fancy' and cannot withstand the toss of lead-acid batteries. The lithium battery cannot withstand the impact of being dropped or thrown during use. When the consequences of the impact are serious, the lithium battery may burn and explode; in addition, the charging of the lithium battery must be matched. Lead-acid batteries can be charged by coin-operated chargers on the side of the road. Finally, on the whole, lithium batteries are the trend in the future, and eventually lead-acid batteries will be replaced by lithium batteries, but this process will be very long. I believe that even in the end, lead-acid batteries still have their own specific application scenarios. Because some of the characteristics of lead electricity cannot be completely replaced by lithium batteries.
