In the production, mixing and subsequent filling of electrolyte, persistent bubbles are a common challenge. These bubbles not only affect accurate metering of the formula, causing batch-to-batch quality variation, but also form voids in later battery assembly, directly affecting the battery's energy density and long-term cycle performance. Traditional physical defoaming methods are often inefficient and struggle to meet the needs of continuous, large-scale production.
To address this core pain point, the Chemi Tech R&D team analyzed in depth the special characteristics of electrolyte systems and launched a series of high-performance dedicated antifoams. Our solution is not simply a generic additive but is based on precise control of surface tension and a fast film-rupture mechanism on the bubble wall. These antifoams are highly compatible with the main components of the electrolyte; at extremely low dosage they quickly penetrate and destroy the bubble film, achieving fast defoaming and long-lasting foam inhibition without negatively affecting key indicators such as conductivity and chemical stability.
The specific application steps are clear and definite: first, our technical support team evaluates samples of the customer's specific electrolyte system to identify the key stage and main cause of bubble generation. Second, based on the evaluation, we recommend a matching antifoam grade and a suggested dosage ratio, usually in the range of 0.05% to 0.2%. Then we guide the customer to add it at a specific process point, such as late mixing or before filtration, to ensure uniform dispersion. Finally, we help the customer establish quality control standards to verify the defoaming effect and its harmlessness to final battery performance.
For example, a manufacturer focused on high-voltage electrolyte systems was troubled by inaccurate filling volumes caused by bubbles on the filling line. After adopting the customized antifoaming solution provided by Chemi Tech, bubbles on its production line were eliminated by more than 95%, filling accuracy improved markedly, and the product showed more consistent interfacial characteristics in customer battery tests. This helped the company stabilize product quality and reduce the defect rate caused by bubble problems.
