Lithium batteries are difficult to replace lead-acid batteries in a short period of time, and now the low-speed electric vehicles on the market are still dominated by lead-acid batteries, even if the new national standard takes effect, the new policy will not be able to replace the lead-acid batteries with lithium batteries in a short period of time. Why is this? The following lithium battery manufacturer to elaborate.
Lithium batteries to replace lead-acid batteries in the general environment background.
Strongly supported by the national policy to lead electric vehicles to lightweight lithium batteries, and lithium batteries to replace lead-acid batteries is a very long-term process, in 2020, including China Tower, a number of companies said they no longer use lead-acid batteries, coupled with the new energy vehicle-powered lithium battery technology stack upgrade, from the safety performance, energy density have been qualitatively improved, the cost of lithium batteries are getting closer to lead-acid batteries. Thus, the market signals a lithium battery to replace the lead-acid battery, but lithium batteries really want to replace the lead-acid battery is not so simple.
1. The cost advantage of lithium batteries is not outstanding
In the current situation, the performance of lithium batteries is not satisfactory, the price of lithium batteries is about 1.5-3 times that of lead-acid batteries, but the maintenance rate is still higher than that of lead-acid batteries. In addition manufacturing costs, lead-acid batteries are undoubtedly the lowest, whether it is electrode materials, electrolyte or assembly environment requirements, etc. are far lower than lithium-ion batteries.
2. The popularity of technical capabilities and the difficulty of reworking long cycle
Lithium battery failure requires professional equipment to repair, the general stores are not equipped with lithium battery repair technology, if you want to return to the factory for repair, the cycle may be very long.
3. Safety performance, lead-acid batteries are undoubtedly better
Even though the lithium battery now adds more protection, lithium iron phosphate battery security is also very high, but compared with lead-acid batteries, there is still a big gap in safety.
4, lithium batteries and lead-acid batteries are polluting to the environment
If you do not use the correct recycling method, lithium battery waste is still polluting the environment, while the lead-acid battery industry has gone through a century-long technology precipitation, as long as there is good supervision, good recycling of lead-acid batteries, the damage to the environment can actually be avoided. And in some specific industries, lead-acid batteries are irreplaceable, so in a short time, lithium batteries are unlikely to replace lead-acid batteries.
The new national standard for electric vehicles stipulates that the weight limit of the whole vehicle, including the battery, should not exceed 55 kg at most. At the same time, the new national standard for batteries on the battery technical conditions, product quality, product specifications have also made strict provisions: 1.
1. requiring batteries to be designed for light weight, increasing energy density rather than weight.
2. mandatory setting of battery cycle charging life, which shall not be less than 350 times.
3. comprehensively raise the technical threshold for access to lead-acid batteries.
With the increasingly fierce competition in the electric bicycle industry, intelligence, lightweight, fast charging, long life, long life, high cost performance, etc. has been a must for electric bicycles, from the lightness of electric bicycles, lithium batteries are indeed a trend.
But no matter how to say, electric bicycle lead to lithium, for the consumer experience or for the industry to help, is ultimately a good thing, hope that the pace of lithium battery electric bicycle further, and in the future lithium battery will slowly become mainstream.
