Wu Hui believes that from the perspective of technological development, companies such as Japan and South Korea basically use ternary, lithium manganate or their mixed materials as the preferred cathode materials for power batteries, while China uses lithium iron phosphate on a large scale, although lithium iron phosphate is not safe in terms of safety. It is guaranteed, but its low energy density leads to a short cruising range of the car. Against this background, domestic companies have also begun to develop power batteries with ternary material systems. BYD has developed lithium iron manganese phosphate, ATL has developed ternary power batteries for BMW, and mainstream power battery companies such as Lishen, AVIC Lithium Battery, and Wanxiang have also Gradually began to develop ternary power batteries, and BAIC's second-generation E150 also began to be equipped with ternary power batteries produced by SK.
In addition, many companies are also developing high-voltage lithium nickel manganese oxide binary materials in the hope of improving the energy density of power batteries. In the field of anode materials, the main focus is on fast charging and discharging. Lithium titanate materials with long cycle life are also used on a large scale in city buses. The leading company Beterui is also actively developing and producing silicon carbon anodes; in the field of electrolytes, high voltage Electrolyte has become the focus of research and development. Jinniu, Shanshan, Tianci, and Xinzhoubang are all actively developing 4.7V or even 5V electrolyte systems. Electrolyte additives have become a hot spot for industry investment; in the field of separators, separator coatings are used in a large number of power batteries. Among them, ultra-thin wet separators coated on one or both sides have become the mainstream application.
Low temperature lithium iron phosphate battery 3.2V 20A -20℃ charging, -40℃ 3C discharge capacity ≥70%
The dry process has a simple process, low equipment investment, and relatively low technical difficulty.
In view of the fact that the dry process is simple and highly reproducible, in terms of output, dry process is still the dominant method in China.
The gap between my country's dry process separators and international separators is small, while the wet process currently has a larger gap. Judging from the pore-forming uniformity of the separator in the SEM picture, the current domestic dry-process separators are getting closer to the foreign level, while the wet-process separators still have a clear gap.
Based on this, we believe that the breakthrough of separators will start from the dry process; the market they will enter is mid-to-high-end power cells and consumer battery cell manufacturers using dry process separators.
In recent years, wet process separators have been put into production one after another, especially the introduction of foreign equipment, which will accelerate the development of wet process. We believe that the wet method will follow the dry method and enter the mid-to-high-end market; it is mainly positioned in mid-to-high-end consumer batteries.
