Lithium battery materials' development trend

Development trend of lithium battery materials

1. In terms of power lithium battery, in terms of passenger cars, foreign countries take modified lithium manganate and ternary lithium battery as the main materials. In China, lithium iron phosphate is mainly used as the main material, but due to the low energy density of lithium iron phosphate, the current trend to ternary lithium battery. Electric buses: Due to the large size of buses, the problem of low energy density can be solved by adding batteries. Buses run for a long time every day and charge more times. Lithium iron phosphate is the best choice for safety and life cycle.  

2.  Development trend of anode materials. Due to mature graphite technology, good stability, the price advantage is obvious. Compared with natural graphite, artificial graphite is more expensive but more consistent, making it the preferred anode material for lithium batteries.  

3. Development trend of electrolytic materials. The electrolyte consists of electrolytic lithium salt, high purity organic solvent and necessary additives and other raw materials. The lithium salt of the electrolyte is mainly lithium hexafluorophosphate, accounting for 40% of the cost of the electrolyte. The total electrolyte accounts for about 10% of the cost of a lithium battery.

4. Development trend of diaphragm materials dry process is relatively mature, high localization rate, occupying a leading position in the current lithium battery market. However, the performance of the diaphragm produced by wet process is better, and with the maturity of ceramic coating technology, the overall situation of dry process will be challenged.
