Battery Slurry Mixing Technology in Energy Storage Industry

With the growing global demand for clean energy, energy storage technology, particularly lithium-ion batteries, has become increasingly important. The key to battery performance lies in the mixing quality of electrode materials, and vacuum defoaming mixing technology is becoming a core process in battery manufacturing.

Key Challenges in Battery Slurry Mixing

Lithium-ion battery electrode slurry consists of active materials, conductive agents, binders, and solvents, requiring extremely high mixing uniformity. Traditional mixing methods tend to produce bubbles, uneven mixing, and agglomeration, which directly affect battery capacity, cycle life, and safety. Vacuum defoaming mixing technology effectively solves these problems through efficient stirring in a vacuum environment.

Main Application Scenarios

• Lithium-ion Battery Slurry: High-precision mixing of positive and negative electrode slurries to ensure consistent electrode performance.
• Supercapacitor Materials: Uniform mixing of electrode materials to improve energy density and power density.
• Solid-state Battery Electrolytes: Development and production of new solid-state electrolyte materials.
• Fuel Cell Catalysts: Improving catalyst dispersion and enhancing reaction efficiency.
• Energy Storage Device Encapsulation Materials: Ensuring uniformity and reliability of encapsulation materials.
