With the advent of the retirement period of power batteries and the constraints of lithium resources, it is imperative for lithium-ion batteries to be developed. However, at present, there are still many difficulties in the lithium-ion battery industry, and the following Pengmi Technology will introduce the difficult status quo of the lithium battery industry in detail, as well as the outlook for the future.
1. The network construction of waste batteries is not perfect, and many waste batteries cannot be effective.
2. The technical level is low, and it is difficult to use the cascade. After the retirement of the power battery, the first echelon utilization, and then dismantling, but the echelon utilization process under the current conditions still has certain difficulties in technology and market.
3. It is difficult to track the battery.
4. The profit model is not clear.
5. The enthusiasm for environmental protection in related aspects is not high, and the importance of waste lithium batteries is low.
For the future development of the lithium battery industry, it is necessary to focus on the study of new production technology, battery producers should do a good job in classification, and relevant departments should establish a sound legal and regulatory system to improve the environmental awareness of the public.
The industrialization path of lithium-ion power batteries focuses on the development of higher energy density batteries. From the perspective of industrial pattern, the global power battery industrialization is gathered in China, Japan and South Korea, and now Chinese enterprises have formed a very large industrialization scale with different technical routes and products. In terms of technical process, the foreign technical route is mainly pyrotechnic, and the main technical route of major domestic power battery enterprises is wet method.
Pengmi Technology - waste lithium battery dismantling line, cascade utilization line, crushing and sorting line, hydrometallurgical line.
Lithium-ion power battery technology is gradually progressing towards higher energy density, cycle life and other indicators. Driven by factors such as cost, safety, and energy storage demand, lithium iron phosphate batteries maintain a high growth rate, but high nickel ternary is still an important technical route for power batteries in the future.
In terms of anode, silicon carbon is an inevitable trend in the development of high energy density. In terms of integration, CTC technology makes the battery itself a part of the body, which is the current development trend of the integration of pure electric vehicle batteries and vehicles.
