Silicon carbon negative electrode as a new lithium-ion battery negative material, to enhance the battery energy density can play a more significant effect than the current graphite negative electrode.

Since 2021, Tesla, Ningde Times and other enterprises have begun mass production of power battery products using silicon carbon negative electrodes, and some negative electrode enterprises have also begun to invest in construction.Silicon carbon negative electrode production line.

Lithium ion battery negative electrode materials are mainly divided into carbon materials and non-carbon materials. At present, commercial lithium ion batteries mainly use graphite in carbon materials as negative electrode materials. The theoretical specific capacity of graphite is 372mA · h/g, while the high-end graphite materials on the market can reach 360-365mA · h/g, so the energy density of corresponding lithium ion batteries has been quite limited. In this context, non-carbonaceous silicon-based anode materials have attracted much attention due to their high theoretical specific capacity, low lithium removal potential, environmental friendliness, abundant reserves, and low cost. High energy density lithium ion battery anode materials.

Silicon carbon anode material enterprises in the upper reaches of the industrial chain, the middle reaches of the battery factory, downstream for the vehicle factory, the whole industrial chain attaches great importance to the research and development and application of silicon carbon anode, silicon carbon anode commercialization process is accelerating.

Grinding is an indispensable part of the production process of silicon carbon anode materials. By grinding the raw materials, the material particles have a larger specific surface area and the mixing is more uniform. The grinding equipment used in the production of silicon carbon anode should have the following requirements:

■ High efficiency and low consumption:High efficiency and low energy consumption;

■ Excellent quality:Grinding product performance is good, batch stability;

■ Equipment stability:Durable not bad, wear-resistant not to change;

■ Easy maintenance:Not easy to fault, good maintenance.

At present, in production and application, more customers choose Yushun's rod-pin nano-sand mill as the first choice for silicon carbon material grinding equipment, which can easily reduce costs and increase efficiency.

The dual-power nano centrifugal sand mill is Yushun's intelligent "star product". It is a stable mass production equipment in the ultra-fine nano field, which can realize the independent operation of dual-power material grinding and material separation.

Grinding structural parts wear-resistant, mechanical seal durable; structural parts of silicon carbide and other more toughness and thermal conductivity of the material, the service life of the extended than the general regular material time 2-3 times longer.

Configurable zirconium beads 0.05mm, can be very good to achieve material and grinding meson separation,finer fineness;Unique centrifugal technology and cyclone separator structure, to avoid the phenomenon of blocking and leakage.

Intelligent PLC control system, Reduce manual errors; circulating cooling system, the machine can run efficiently; adoptAutomated touch screen, The operation is intuitive, and the operating status of the equipment and related text instructions are displayed on the touch screen for easy maintenance.
