Description
Technical Field
The invention belongs to the technical field of lithium ion batteries, and particularly relates to high-nickel ternary cathode slurry for a lithium battery and a preparation method of the high-nickel ternary cathode slurry.
Background
With the advocation of energy conservation and emission reduction, new energy automobiles gradually move to the public. The preparation of new energy automobiles and power batteries is indispensable. The lithium ion battery has the outstanding advantages of high energy density, environmental friendliness, no memory effect, long cycle life, small self-discharge, environmental protection and the like, and is popular. And materials used therein have also been the focus of research, particularly positive electrode active materials.
Currently, lithium battery positive electrode materials that have been commercially used include lithium cobaltate, lithium manganate, lithium iron phosphate, and nickel cobalt manganese ternary materials. Lithium cobaltate is used as the most mature positive electrode active material of the lithium ion battery at present, the actual capacity of the lithium cobaltate is about 140mA · h/g, and is only about half of the theoretical capacity (274mA · h/g), and in the repeated charge and discharge process, the structure of the active material is changed after repeated shrinkage and expansion due to repeated insertion and extraction of lithium ions, so that the internal resistance of the lithium cobaltate is increased, the capacity is reduced, meanwhile, the lithium cobaltate is used as the positive electrode active material, the cost of the lithium ion battery is obviously improved, the profit is extremely small, and the lithium cobaltate is urgently required to be replaced. In the initial development stage of domestic electric automobiles, a power battery is dominated by a battery adopting a lithium iron phosphate anode material, and although the cycle life of the battery made of the anode material is long, the energy density is low, so that the endurance mileage of the electric automobile is short. And the specific capacity of the lithium manganate is lower, and the capacity attenuation is serious at high temperature.
The ternary material has a great advantage over the above-described positive electrode active material. Especially high nickel ternary material, such as ternary NCM811 cathode material, with specific discharge capacity up to 200mAhg-1And the cost is low, so that the method is widely concerned. However, for high nickel ternary materials, processability is a problem. The high-nickel ternary material has too high surface alkalinity, is easy to absorb water in the homogenizing and coating processes, causes jelly-like slurry, deteriorates the processing performance and influences the performance exertion of the electrode material. Therefore, high nickel is being usedIn the process of preparing the anode slurry by the ternary material, harsh conditions are required, so that the preparation cost is increased. Therefore, the processability of the high-nickel ternary cathode material is a problem to be solved urgently.
