II. Core Product Analysis (1): Mixing Homogenization Equipment - Precise Homogenization, Laying a Solid Foundation for Dry Process Production

Mixing homogenization is the primary link of dry process production, and the dispersion uniformity of materials directly determines the subsequent film forming quality, electrode performance and product batch stability. Relying on the 18-year technological accumulation of the Advanced Energy Storage Laboratory in the field of powder material dispersion, Tsingyan Electronics' independently developed mixing homogenization equipment features the core advantages of "low residue, high uniformity and wide compatibility", addressing the industry pain points of traditional mixing equipment such as uneven material mixing, high residual rate and narrow adaptability, and providing high-quality material guarantee for dry electrode production.

The core technological advantages of the equipment are reflected in three aspects: First, extreme homogenization precision. Inheriting the laboratory's research results in powder dispersion technology, it adopts a multi-stage shear and diffusion collaborative design combined with an intelligent speed control system, realizing particle-level uniform dispersion of materials. It effectively solves the problem of uneven mixing of active materials, binders and conductive agents, significantly improving the consistency, mechanical integrity and electrochemical stability of electrode sheets, with a material residual rate of less than 0.5%, far exceeding the industry average. Second, high compatibility adaptation. It can flexibly adapt to multiple systems such as lithium batteries and sodium batteries, support the mixing and homogenization of various electrode materials such as silicon-based, graphite, ternary and lithium iron phosphate, and is also compatible with manganese dioxide, oxide electrolytes and sulfide solid electrolytes, meeting the formula verification and production needs of different customers. Third, intelligent and efficient operation and maintenance. Equipped with a complete intelligent control system, it realizes automatic control of the whole process of feeding, mixing and discharging, supports precise parameter adjustment and data traceability. Meanwhile, the optimized equipment structure design facilitates cleaning and maintenance, greatly reducing labor costs and operation and maintenance difficulty.

In terms of application scenarios, Tsingyan Electronics' mixing homogenization equipment is widely suitable for laboratory testing, pilot and small-scale mass production needs. It can not only meet the material formula verification needs of scientific research institutions and enterprise R&D departments, providing reliable equipment support for the R&D of new dry electrode materials, but also adapt to the large-scale production of new energy battery manufacturers, seamlessly connecting with subsequent film forming equipment to form an efficient and linked production process. Its closed design effectively suppresses dust flying, protects the operating environment, prevents cross-contamination of materials, conforms to the concept of green manufacturing, and further reduces the environmental protection pressure in the production process.

III. Core Product Analysis (2): Integrated Film Forming Equipment - Integrated and High-Efficiency, Breaking the Bottleneck of Large-Scale Production

Film forming and compounding are the core processes of dry electrode production. Traditional equipment mostly adopts the mode of "separated film forming and compounding", which has problems such as cumbersome processes, large material transfer loss, low film forming precision and irregular winding, seriously restricting production efficiency and product yield. Tsingyan Electronics has developed integrated film forming equipment (including single-sided film forming and compounding integrated machine, double-sided film forming and compounding integrated machine) in a targeted manner. With "integration, high precision and high adaptability" as the core, it realizes the integrated continuous production of "film forming - compounding - winding", breaking the technical bottleneck of large-scale dry process production.

Combined with different production needs, Tsingyan Electronics' integrated film forming equipment forms two series with different focuses and flexible adaptation:

The single-sided film forming and compounding integrated machine focuses on formula verification and process optimization in the laboratory testing and pilot stage. It has precise temperature control capability, with the roll surface temperature uniformity reaching ±1.5°C for electric heating and ±1°C for oil heating to ensure production stability; it supports single-sided film forming and on-line compounding verification, reducing the dependence on the self-supporting property of the film, thereby reducing the usage of PTFE and effectively controlling production costs; equipped with edge trimming + automatic deviation correction functions, it improves the neatness of film edges and winding alignment. At the same time, it is equipped with a complete servo control system, with the on-line roll gap adjustment precision up to ±1μm, supporting a smooth transition from experiment to pilot and shortening the product development cycle.

The double-sided film forming and compounding integrated machine is mainly for pilot and small-scale mass production needs, with higher production efficiency and wider adaptability. The equipment provides a variety of roll size specifications to choose from, with diameters ranging from 200-500mm and lengths ranging from 300-1000mm, and the maximum film forming speed up to 50m/min. It supports a quick roll change design for more convenient maintenance; adopting the roll-to-roll integrated continuous preparation process of "double-sided synchronous film forming - hot pressing compounding", it can realize double-sided film forming and compounding with current collectors at the same time, with automatic unwinding and winding without material transfer, effectively avoiding problems such as belt breakage and wrinkling caused by insufficient strength of self-supporting films, and greatly improving production efficiency; it is also equipped with edge trimming + automatic deviation correction functions to ensure neat film edges and regular winding, meeting the stringent requirements of large-scale production for product consistency.

In addition, Tsingyan Electronics' integrated film forming equipment is intelligently designed as a whole, equipped with a multi-variable full closed-loop intelligent control system for "pressure - roll gap - tension - temperature", which can realize precise regulation and real-time monitoring of various parameters to ensure that key indicators such as electrode sheet thickness and areal density meet the standards stably. The equipment is compatible with a variety of electrode materials and systems, and can flexibly adapt to the production of electrode sheets of different specifications and types. Whether it is lithium battery electrode sheets, supercapacitor electrode sheets or solid-state battery electrodes, it can achieve efficient film forming and compounding, providing customers with customized production solutions.

IV. Synergy of Two Sets of Equipment: Building a Full-Process Solution for Dry Process Intelligent Manufacturing to Empower Industrial Upgrading

Tsingyan Electronics' mixing homogenization equipment and integrated film forming equipment are not isolated, but form a full-process collaborative system of "pre-process homogenization - post-process film forming", realizing the intelligent manufacturing value of 1+1>2, and providing new energy enterprises with a one-stop dry process production solution from material processing to finished electrode sheets.

In actual production, the mixing homogenization equipment first performs precise homogenization on raw materials such as active materials, binders and conductive agents to ensure uniform material dispersion without agglomeration, providing high-quality raw materials for the subsequent film forming link; the integrated film forming equipment undertakes the homogenized materials and directly completes the whole processes of film forming, compounding and winding without intermediate material transfer, reducing material loss and improving production efficiency. At the same time, both sets of equipment can be connected to the intelligent production system to realize linked parameter regulation and real-time production data traceability, facilitating enterprises to achieve digital and intelligent management of the production process, further reducing production costs and improving product yield.

Compared with traditional dry process equipment, Tsingyan Electronics' integrated collaborative solution has three core advantages: First, green and environmental protection. The whole process is solvent-free, getting rid of the dependence on organic solvents such as NMP, eliminating environmental pollution and potential safety hazards caused by solvent volatilization, and reducing production energy consumption at the same time, conforming to the "dual carbon" goals and the trend of green manufacturing. Second, high efficiency and energy saving. The integrated design greatly shortens the production process, reduces equipment floor space and labor input, and at the same time cuts down material loss and energy consumption. It is estimated that it can help enterprises reduce comprehensive production costs. Third, flexible adaptation. It can meet the full-cycle needs from laboratory testing and pilot to mass production, support the production of multi-system and multi-specification products, help enterprises quickly respond to market changes, and shorten the R&D and landing cycle of new products.
