As we all know, compared with lead-acid batteries, lithium batteries have the advantages of high energy density, long life, small size and light weight. However, lead-acid batteries are still the mainstream in the market. why?
First of all, the cost advantage of lithium batteries is not outstanding. According to many dealers selling lithium electric vehicles, under normal circumstances, the price of lithium batteries is 1.5-2.5 times that of lead-acid batteries, but the service life is not good and the maintenance rate is also high.
Second, the maintenance cycle is too long. Once a lithium battery fails to repair, it will take about a week or even longer. The reason is that the dealer cannot repair or replace the defective battery inside the lithium battery. It must be returned to the manufacturing company, and the manufacturer will disassemble and assemble. And many lithium batteries cannot be repaired.
Third, compared with lead-acid batteries, safety is a flaw.
Lithium batteries cannot withstand drops and impacts during use. After piercing the lithium battery or severely impacting the lithium battery, the lithium battery may burn and explode. Lithium batteries have relatively high requirements for chargers. Once the charging current is too large, the protective plate in the lithium battery may be damaged and cause burning or even explosion.
Large-brand lithium battery manufacturers have a higher product safety factor, but the price is also higher. The products of some small lithium battery manufacturers are cheap, but the safety is relatively low.
