Annual meeting notice

June 65438+February 2020 16- 18, Li was named as the 2020 Hi-Tech Lithium Battery &; The annual meeting of electric vehicles (concurrent activities: the 10th anniversary celebration of Hi-Tech lithium battery and the Golden Globe Award ceremony of Hi-Tech lithium battery) will be held at Hyatt Regency Shenzhen Airport.

Dongguan Lizard Intelligent System Co., Ltd. is the sponsor of this conference. At that time, Li Wanli, general manager of Lizard, will give a keynote speech entitled "Trend Analysis of Pulping Process in the Pre-stage of Power Battery".

Realizing the high safety and consistency of power batteries is still an unavoidable focus topic in the new energy automobile industry.

Industry research data show that 70% of the consistency of power battery pole piece depends on the consistency of slurry and pulping process, and the consistency of pole piece has great influence on the final product of power battery.

At the same time, improving the production capacity of a single production line of power batteries has become an urgent need for power battery enterprises to improve production capacity, reduce costs and increase efficiency. In the case that traditional equipment and technology can't meet the demand, innovative process equipment has become a new choice for power battery enterprises.

As a rising star in the field of advanced pulping intelligent equipment for lithium batteries, Dongguan Lizard Intelligent System Co., Ltd. (referred to as "Lizard") is well known by more and more power battery and material enterprises for its innovative pulping equipment technology.

Lithium battery, a senior engineer, learned that lizard pulping technology originated in Germany. While cooperating with German enterprises for a century, the company has carried out a lot of verification and improvement in the field of battery technology, and has successively developed a high-speed fine dispersion system and a fully automatic slurry treatment system.

Li Wanli, general manager of Lizard, said that the high-speed pulping system developed by the company is especially suitable for dispersion pulping of anode and cathode materials of lithium battery slurry and pulping applications of various nano materials, such as nano-alumina, nano-lithium titanate, nano-conductive carbon black, VGCF and carbon nanotubes, with high production efficiency and excellent dispersion quality.

"After treatment, the fineness of the slurry can be restored to the granularity of incoming materials, the internal resistance is reduced, and the adhesion between copper foil or aluminum foil and the slurry, the fineness and fluidity of the slurry, the consistency of capacitance, solid content and conductivity are improved, which can effectively solve the problems of agglomeration effect, easy delamination and difficult precipitation." Li Wanli emphasized that the lithium battery slurry is better dispersed, which not only ensures the uniformity of the slurry, but also improves the production efficiency.

Among them, the high-speed premixer independently developed by lizard can produce high-quality and high-specification products at one time.

The equipment structure is made of all stainless steel and some alloy materials, which has super corrosion resistance and high temperature resistance. Three process steps of mixing, homogenization and dispersion can be realized on one machine, and the completely continuous operation mode can meet different process requirements.

Li Wanli said that a completely closed system can prevent the discharge of dust and solvent, greatly shorten the production time, thus preventing the formation of caking, improving the production efficiency, fully stirring the solid and liquid, and reducing the production cost.

In the process of material dispersion, the high-speed dispersion machine independently developed by lizard adopts vertical cavity structure, and the slurry can all enter the dispersion cavity without dead ends.

All contact materials of the high-speed disperser are made of stainless steel (SUS3 16L), and the smooth inner surface (Ra 0.8υm) avoids particle damage, and the energy frequency transmitted to the slurry is high, which does not damage the material itself, and is easy to clean, thorough and very convenient, and eliminates material pollution during refueling.

The stator and rotor of the disperser are made of special materials, which play a protective role under the action of high shear force and prevent wear and corrosion. At the same time, the gap can be flexibly adjusted according to the viscosity of different materials to ensure the uniformity and stability of the treatment effect.

"The lizard high-speed disperser runs for a long time, can work continuously, is not easy to cause shaft eccentricity, has high efficiency and low maintenance cost." Li Wanli added.

Li Wanli has been deeply involved in the lithium battery industry for more than ten years, and is well versed in the role of intelligent manufacturing in the new energy industry. Whether it is a high-speed fine dispersion system, an automatic slurry processing system, or the improvement of product quality brought by big data, it reflects the rooting of the lizard in the field of new energy.

Lizard will also continue to devote itself to the first stage pulping process of lithium battery industry, continue to provide efficient, high-concentration and high-stability equipment products, and develop core products such as feeding, premixing and decentralized pulping systems in a targeted manner to help battery enterprises improve product performance and reduce costs.
