SUNKAIER's fluid technology and kneading technology is mainly reflected in the following:
Kneading operation is often accompanied by heating or cooling process. On the one hand, the unit volume of SUNKAIER kneader has enough heat transfer surface, and on the other hand, the moving parts should be able to stably and rapidly scrape the adherent materials on the heat transfer surface and send them back to the high shear zone, which can prevent the materials from sticking to the wall and have self-cleaning function at the same time.
SUNKAIER has the ability to analyze the dynamic characteristics of differential mixing kneading machine and simulate the three-dimensional flow field, which ensures that SUNKAIER kneading machine has only a high shear area with a small gap, so that high shear stress can be generated and materials can be dispersed. At the same time, the shapes of parts (such as impeller shape) that are driven in the polymer mixing machine can be achieved. It can ensure that the movement path and range of materials in the kneader continuously pass through the high shear area with small clearance, and disperse evenly after repeated shear.
A large heat transfer area facilitates accurate and uniform temperature control. Suitable temperature, slurry fluidity is good, easy to disperse.
Material composition of lithium battery mainly includes: positive material, negative material, diaphragm, electrolyte.
Among the lithium cathode materials, the most commonly used materials are lithium cobaltate, lithium manganate, lithium iron phosphate and teradic materials (nickel-cobalt manganese polymer).
At present, natural graphite and artificial graphite are the main anode materials for lithium batteries. The anode materials under exploration include nitride, PAS, tin-based oxide, tin alloy, nano anode materials, and some other intermetallic compounds.
The market-oriented diaphragm materials are mainly polyethylene (PE) and polypropylene (PP) -dominated Polyolefin separator. In the structure of lithium battery, diaphragm is one of the key inner components.
The electrolyte consists of high purity organic solvent, lithium electrolyte salt, necessary additives and other raw materials
