Lithium battery material production process -Lithium - Ion Battery Equipment
As the core of the power lithium-ion battery, the cathode material accounts for about 30~40% of the manufacturing cost of the new energy vehicle. At present, there are three important types of large-scale market applications, including lithium iron phosphate, lithium manganate, and ternary materials nickel-cobalt lithium manganate and nickel-cobalt aluminate. Among them, lithium iron phosphate and lithium manganate materials do not have much room for technological breakthroughs in basic research, and their energy density and important technical indicators are close to the application limit. From the perspective of technological progress, ternary materials have gradually become the mainstream of power lithium battery cathode materials due to their advantages of high energy density, long cycle life, and high reliability.
Driven by the rapid development of lithium-ion batteries and their downstream industries, lithium-ion battery cathode materials have risen rapidly. In 2016, the global sales of lithium-ion battery cathode materials reached 317,400 tons, a year-on-year increase of 42.1%. The average annual compound growth rate from 2011 to 2016 was 32.17%. From the perspective of application structure, the lithium battery cathode material market can be subdivided into the small lithium battery cathode material market and the power lithium battery cathode material market. The cathode materials for small lithium batteries mainly include lithium cobalt oxide, ternary materials and lithium manganate, while the cathode materials for power lithium batteries mainly include lithium manganate, lithium iron phosphate and ternary materials.（Lithium - Ion Battery Equipment）
Lithium-ion battery cathode material production process
The performance of the lithium-ion battery cathode material directly affects the performance of the lithium-ion battery, and its cost also directly determines the cost of the battery. There are many industrial production processes for cathode materials, the synthesis route is relatively complex, and the control of temperature, environment, and impurity content is also relatively strict. There are many industrial production processes for positive electrode materials, the synthesis route is relatively complicated, and the control of temperature, environment, and impurity content is also relatively strict. The important positive electrode materials include lithium cobalt oxide, lithium manganate, lithium iron phosphate, ternary materials, etc. .
The calcination technology adopts the new microwave drying technology to dry the positive electrode material of lithium ion battery, which solves the problems that conventional lithium ion battery positive electrode material drying technology takes a long time, slows capital turnover, uneven drying, and insufficient drying depth. The specific features are as follows:
1. The use of microwave drying equipment for lithium-ion battery cathode materials is fast and fast, and deep drying can be completed in a few minutes, which can make the final moisture content reach more than one thousandth;
2. The drying is uniform and the drying quality of the product is good;
3. The cathode material of lithium-ion battery is highly efficient, energy-saving, safe and environmentally friendly;
4. It has no thermal inertia, and the immediacy of heating is easy to control. Microwave sintered lithium-ion battery cathode material has the characteristics of fast heating rate, high energy utilization rate, high heating efficiency, safety, hygiene and pollution-free, and can improve product uniformity and yield, and improve the microstructure and performance of sintered materials.
