The price of lead-acid batteries has risen so much, why didn't lithium electric vehicles make a turnaround?

There is a very prominent contradiction in the development of the electric vehicle industry to this day, that is, lead-acid electric vehicles and lithium batteries are difficult to integrate. Although both are electric vehicle companies, they are taking completely different paths. For example, the supporting system of lead-acid electric vehicles has been highly perfected. The supporting system between all parts such as batteries, plastic parts (frames and iron parts), controllers, chargers, etc. has been very mature, and the products have formed a series of products. , Standardization; as long as a small company has a site, all parts are purchased outside, without any assembly line, only simple screwdrivers, wooden hammers, wrenches and other assembly tools can become a veritable vehicle company. Until today, this Form factories still exist in large numbers. This has also caused the problems of low industry entry barriers and excessive competition. Up to now, there are thousands of companies (including some companies without production licenses). On the contrary, if the lithium battery company relies on the above-mentioned screwdriver + wooden hammer to establish a factory, the product is about to go wrong. Although all the parts and components of the lithium battery can also be purchased out, the lack of core frame design and manufacturing technology will result in the result of not being able to sell good prices or even making profits. Although lithium electric vehicle parts have also achieved market-oriented configuration, it is necessary to match all purchased parts and components to form a matching and high efficiency, and the technical and process difficulties are far greater than those of lead-acid electric vehicles. A good lithium battery is exported to developed countries such as Europe and the United States. The retail price is 2000-2500 US dollars; but a lead-acid electric car can only be sold in less developed countries, and the price is basically 450-600 US dollars. The difference lies in the details of the manufacturing process, the technical gap of the battery and the accessories. Why can lead-acid electric vehicles firmly occupy such a high market share? The key point is that lead-acid electric vehicles are not only at the price that ordinary people can accept and can be purchased multiple times; more importantly, the current market maintenance of lead-acid electric vehicles is very sound, popular, convenient and fast. In any city or township area, once the lead-acid electric vehicle breaks down or the power supply is exhausted, you can easily find a repair shop in less than 10 minutes in the form of a cart, handle the fault or replenish the power supply, and let the vehicle continue to drive To the destination. On the contrary, lithium electric vehicles have many advantages such as lightness, flexibility, and long riding mileage, which are beyond the reach of lead-acid electric vehicles. However, the price of lithium electric vehicles is higher, the price of replacement batteries is higher, and the cost-effective advantage is not prominent. There is a very prominent problem. However, once the lithium-ion battery fails, it will cause consumers to cry out for trouble, and the repair time is extremely long. According to reports, the current failure rate of domestic lithium-ion batteries is much higher than that of domestic lead-acid batteries. This is an important reason why lithium electric vehicles have not been widely promoted in the 1989 time when they entered the domestic market. However, compared with lead-acid batteries, domestic lithium-ion batteries are progressing: it is reflected in the continuous expansion of large-scale companies; the price is falling rapidly and the quality is improving. If the price of lead-acid battery raw materials continues to rise, the price gap between lead-acid batteries and lithium-ion batteries will narrow, and vehicle companies will find ways to use lithium-ion batteries as power sources. Because once the weight of the power supply drops, it can provide a broad development space for the design and manufacturing of the whole vehicle. Driving a lithium battery can make consumers truly feel the sensory stimulation and physical and mental enjoyment brought by high-power discharge. Lithium-ion batteries are not acceptable. With the influx of companies investing in new energy electric vehicles, there is no bottleneck in the quality and performance improvement of lithium-ion batteries in my country. To build a car in the future depends on the face of the lithium-ion battery.
