New Energy Filtration Solutions
In the photovoltaic industry chain, solar cell modules are the core and most important part of the solar power system. The manufacturing process of photovoltaic products is extremely sensitive to the presence of pollutants. Impurities such as moisture and particles will directly affect every process of product manufacturing. Particle pollution will cause defects on the surface of the battery, affecting the quality of the battery.
Photovoltaic Cell Process Flow:
l PERC Monocrystalline Solar Cell
l Conventional Polycrystalline Solar Cells
Lithium-ion Battery Coating Process:
As a third-generation battery technology, lithium-ion batteries have been widely used in the field of electronic products due to their high energy storage ratio, long cycle life, and environmental friendliness. Meanwhile, with the rapid development of the electric vehicle industry, the market prospects for high-capacity power lithium-ion batteries are vast. The electrode manufacturing of lithium-ion batteries, the positive electrode slurry is composed of binders, conductive agents, positive electrode materials, etc; The negative electrode slurry is composed of binders, graphite carbon powder, etc. The preparation of positive and negative electrode slurry involves a series of processes such as mixing, dissolution, and dispersion between liquids and solid materials, and is accompanied by changes in temperature, viscosity, and environment. In the positive and negative electrode slurry, the dispersibility and uniformity of granular active materials directly affect the movement of lithium ions between the two poles of the battery. Therefore, the mixing and dispersion of slurry for each electrode material is crucial in the production of lithium-ion batteries. The quality of slurry dispersion directly affects the quality of subsequent lithium-ion battery production and the performance of the products.
Membrane Solutions uses advanced equipment and technology to strictly control its filtration products, providing assistance for stable, safe, and reliable production in the new energy industry.

Cap-SL Capsule Filter
The unique structural design of the Cap-SL series filter cartridges eliminates the need for cleaning the filter after cartridge replacement, reducing both filter handling costs and cleaning expenses. It prevents direct contact with the slurry, making it suitable for filtering toxic and harmful slurries. The capsule structure reduces the gap between the filter shell and the inner core, minimizing slurry residue. It can be paired with different sizes of inner cores, with lengths of 5", 10", and 20" available to meet various flow rate requirements. The C2SL series is a specially designed capsule filter for ultra-high flow rates, suitable for high-speed coating production lines. It features a built-in 7-core filter with a large-capacity design, greatly extending the service life of a single filter, reducing replacement frequency. It also includes a bottom liquid discharge design for slurry recovery and reuse. The capsule shell design, combined with a high dirt-holding capacity depth-wound inner core structure, is widely used in the slurry coating processes for both positive and negative electrodes in lithium batteries and MLCC.
