In recent years, thanks to the government's strong support for the new energy automobile industry, China has become the key promotion market for new energy automobiles and the largest electric vehicle market in the world. Benefiting from the booming production and marketing of new energy vehicles, power batteries as the core components of the new energy automobile industry chain ushered in a good opportunity for development, and many enterprises began to accelerate the distribution of power battery market. At the same time, due to the surge in demand for power lithium batteries, the explosive market demand is transmitted to the related material industries such as cathode materials, negative materials, diaphragms and electrolytes, as well as the upstream lithium resources and equipment manufacturing, and the cooperation linkages between the industrial chains are intensifying.
Recently, the fourth batch of power battery enterprise catalogue published by the Ministry of Industry and Information Technology has accelerated the competitive system of the market, some small-scale enterprises with imperfect safety and quality system and lack of independent research and development capacity will gradually be replaced, but this has not affected the enthusiasm of enterprises to invest and expand production. The industry calls for the establishment of a certain technical threshold, in order to be more conducive to the healthy competition of enterprises and promote the healthy development of large-scale battery enterprises. At the same time, Samsung SDI, LG Chemistry and other foreign-funded manufacturers failed to be selected in the new regulations, which greatly improved the competitiveness and enthusiasm of independent brands.
At present, power batteries have become the biggest engine of lithium battery growth. With the expected sales of 700,000 new energy vehicles this year, investment and expansion in power lithium batteries are still accelerating. According to incomplete statistics by journalists, in the first half of this year, 54 listed companies in the upper, middle and lower reaches of power batteries issued investment expansion plans, with a total investment of nearly 116 billion yuan. These news are great good news for the magnetic separation equipment industry. Lithium batteries need to be removed by battery material before production is completed.
At present, the market-oriented cathode materials for lithium batteries include lithium cobalt oxide, lithium manganate, lithium iron phosphate and ternary materials. Subdivision of cathode materials can cause many problems due to metal impurities. It has great influence on battery discharge and safety. Metal foreign bodies in products exist in trace amounts and all of them are in the PPb level, but no matter how much they are, they will cause different degrees of damage to batteries. Metal foreign bodies include Cn, Zn, Ni and so on in the form of simple substances besides iron, which are magnetic in part and magnetic in the case of impurities. Most of them can be removed by iron removal equipment in the production process of cathode materials, so that the content of magnetic foreign matter can reach below 10PPb (calculated by the existence of an iron element, the content of self-generated electricity generated by the positive plate of the battery is 35ppb), which can greatly reduce the risk, because the content itself is already very low. Therefore, the existence of the material is not completely uniform, so there is a low voltage condition of the battery part.
The dry magnetic separator for battery powder developed and manufactured by Wandaye is especially suitable for separating fine mineral powder particles. For example, the removal of iron and titanium impurities from minerals such as feldspar powder, quartz powder and kaolin powder, and the purification of powders such as ceramics, chemical industry, medicine, electronics, positive and negative materials, graphite and silica.
