Why can't lithium-ion batteries replace lead-acid batteries for a long time?

Compared with lead-acid batteries, lithium-ion batteries have the advantages of high energy density, long life, small size, and light weight. A few years ago, some people said that lead-acid batteries would be replaced by lithium-ion batteries. However, many years later, lead-acid batteries are still the mainstream in the market. So where are the important obstacles to the replacement of lead-acid batteries by lithium-ion batteries? First, the cost-effective advantage of lithium-ion batteries is not outstanding. According to many dealers who sell lithium electric vehicles, the price of lithium-ion batteries is 1.5-2.5 times that of lead-acid batteries, but the service life is not much better, and the repair rate is also high. Second, the long repair time severely restricts the use of consumers. Once the lithium-ion battery fails to be repaired, it takes about a week or even longer, which makes consumers wait impatient and lose confidence in using it. The reason is that the dealer cannot repair or replace the defective battery cell inside the lithium-ion battery. It must be delivered to the manufacturing company by express delivery, and the battery will be repaired through professional equipment. This is one of the keys restricting the large-scale replacement of lead-acid batteries by lithium-ion batteries. Third, lithium-ion batteries are too delicate to withstand the toss of lead-acid batteries. Lithium batteries cannot withstand the impact of being dropped or thrown during use. Once the lithium-ion battery is punctured, or the lithium-ion battery is broken by a severe impact, the lithium-ion battery may burn and explode; the lithium-ion battery will charge The requirements of the device are very high, and it cannot be charged with a coin-operated charger on the side of the road like a lead-acid battery. Once the current is too large, the protective plate in the lithium-ion battery may break down and cause burning or even explosion. On the whole, lithium-ion batteries are a trend, but they should not be blindly optimistic! If these problems are not resolved, lead-acid batteries will still not be able to replace them in the next five years!
