We all know that lithium battery manufacturers of big brands have a relatively high safety factor, but the price is also relatively high. The products of some small lithium battery manufacturers are cheaper, but the safety is relatively low. Recently, there have been many fire accidents of lithium batteries, even the frequent fires of the large enterprise Tesla, which makes people inevitably have new thinking about the safety of lithium batteries.
Compared with lead-acid batteries, lithium 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 will be replaced by lithium batteries. However, many years have passed, and lead-acid batteries are still the mainstream in the market. So where is the main obstacle for lithium batteries to replace lead-acid batteries?
Since lithium batteries have so many advantages, why can’t lithium batteries replace lead-acid batteries?
First, the cost-effective advantages of lithium batteries are not prominent.
According to many dealers who distribute lithium electric vehicles, the price of lithium 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.
We all know lead-acid batteries need maintenance, just like adding distilled or deionized water. What tools do you usually use?
Second, the long repair time seriously restricts the use of consumers.
Once a lithium battery fails to be repaired, it takes about a week, or even longer, which makes consumers impatient and loses confidence in using it. The reason is that dealers are unable to repair or replace batteries with internal problems in lithium batteries, so they must be delivered to the manufacturing company by express delivery, and the batteries are repaired with professional equipment. This is one of the keys to restricting the large-scale replacement of lead-acid batteries by lithium batteries.
Third, lithium batteries are too “delicate” and cannot withstand tossing like lead-acid batteries.
During the use of lithium electric vehicles, they cannot withstand the impact of throwing and throwing. Once the lithium battery is pierced, or the lithium battery is broken by a violent impact, the lithium battery may burn and explode; the lithium battery has very high requirements on the charger. High, you can’t use the coin charger on the side of the road to charge it casually like lead-acid batteries. Once the current is too large, it may break down the protective plate in the lithium battery and cause combustion or even explosion.
In short, whether it is safety issues or cost of lithium batteries, it is not conducive to its promotion. Judging from the current technology, lead-acid batteries are still the main ones.
