Will Lithium Batteries Replace Lead-acid Batteries?

- Dec 05, 2019-

Lead-acid batteries are not environmentally friendly, but the price is low. The environmental protection of lithium batteries is based on high cost and a perfect recycling mechanism. They are all cars, but the degree of industry regulation is also different.

The lead-acid battery takes 40V · 20ah as an example, the theoretical capacity is 960w, and the price is about 600 yuan. The cost of a lithium battery and lithium iron phosphate is 1300 yuan / 1kwh, and a nickel-cobalt-manganese ternary lithium battery is 1,500 yuan. Around / 1wkh, the cost is more than double that of lead acid.

Vehicles using lead-acid batteries are often low-cost electric bicycles or tricycles. Mass-produced vehicles sell for less than 1,000 to 3,000 yuan. How many people can accept that the car price will rise by 1,000 after replacing the battery pack?

Again: there are too few people willing to pay for environmental protection, and more people are looking for benefits. Lead-acid batteries are still inexpensive for most people, as long as they can achieve the same function.

The factors that hinder the use of lithium batteries in electric bicycles are not only cost restrictions, but also a great obstacle to recycling.

The volume of auto companies is very large, the scale of tens of thousands or even hundreds of thousands of employees is very exaggerated, and the asset evaluation is also tens of billions of billions. Such enterprises do not have to worry about using any battery because they can't afford it. There are strict rules for the recycling and secondary use of power batteries. Every step from the ground to packaging to loading the battery is strictly coded to upload information. Secondly, these electric vehicles are also monitored almost full-time under the restrictions of annual inspection and other regulations. After the power battery has completed the use cycle, it will return to the manufacturer from the after-sale and the battery manufacturer from the manufacturer, and these links will be re-coded.

In the end, the qualified batteries are sent to the energy storage power station, and the unqualified batteries are remanufactured at a rate of more than 95%. During the period, each link is completed under strict monitoring. There is no dare to be arbitrary in this process. , Including investing to build a store also requires tens or millions of SSSS.

The cost of secondary battery manufacturing and step utilization is not lower than the production of new batteries. These pressures cannot be borne by such small businesses and small businesses. If the pressure is too great, they can be picked. If there are loopholes in these links, these batteries will flood into disasters. Lithium batteries, which should not pollute the environment, have also become a source of pollution.

Therefore, the actual situation determines that it is not the time for electric bicycles to use lithium batteries. Only non-motorized vehicles can have changes after they have a sound management mechanism. Of course, the problem of manufacturing costs can be broken through.
