Current status of lithium battery cathode material market and analysis of processing technology

Current Status of Lithium Battery Cathode Material Market Cathode materials, as the core of power lithium batteries, account for about 30-40% of the manufacturing cost of new energy vehicles. At present, there are three types of lithium iron phosphate, lithium manganate, and ternary materials, lithium nickel cobalt manganate and lithium nickel cobalt aluminate. Among them, lithium iron phosphate and lithium manganate materials do not have much technology to break through the space in basic research, and their energy density and critical technical indicators are close to the limit of use. 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, longer cycle life, and higher reliability. Driven by the rapid development of lithium batteries and their downstream industries, lithium battery cathode materials have increased rapidly. In 2016, the global sales of lithium battery cathode materials reached 317,400 tons, a year-on-year increase of 42.1%, and the average annual compound growth rate from 2011 to 2016 was 32.17%. . From the perspective of the use 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. Small-scale lithium battery cathode materials mainly include lithium cobalt oxide, ternary materials and lithium manganese oxide, while power lithium battery cathode materials mainly include lithium manganate, lithium iron phosphate and ternary materials. Lithium battery cathode material processing technology Lithium battery cathode material.jpg The performance of lithium battery cathode material directly affects the performance of lithium battery, and its cost directly determines the cost of the battery. There are many industrialized processing procedures for cathode materials, the synthesis route is relatively complicated, and the control of temperature, environment, and impurity content is relatively strict. There are many industrial processing procedures for cathode materials, and the synthesis route is relatively complicated. The control of temperature, environment and impurity content is also strict. The cathode materials mainly include lithium cobalt oxide, lithium manganate, lithium iron phosphate, ternary materials, etc. . The calcination technology adopts microwave drying technology to dry the cathode material of lithium battery, which has dealt with the long time of conventional lithium battery cathode material drying technology, which makes the capital turnover slower, and the drying is uneven, and the drying depth is not enough. The detailed features are: 1. The use of microwave drying equipment for lithium battery cathode materials is fast and rapid, 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 average, and the product drying quality is good; 3. The lithium battery cathode material is highly efficient , Safety and environmental protection; 4. It has no thermal inertia, and the immediate heating is easy to control. Microwave sintered lithium battery cathode materials have the characteristics of fast heating speed, high energy utilization, high heating efficiency, safety and health and no pollution, and can improve the average product and yield, and improve the microstructure and performance of the sintered material.
