With the explosive growth of the new energy industry, the application of hydrated silica is expanding from traditional fields to high-end markets. In the field of lithium batteries, as an inorganic ceramic coating material, it can improve the thermal stability of the separator (temperature resistance increased from 130 ℃ to 180 ℃), reduce internal resistance by 15%, and extend battery cycle life by 20%. For example, CATL uses white carbon black coated separators in power lithium batteries, which increases battery energy density by 5% and reduces costs by 8%.


In the field of hydrogen energy, white carbon black based composite materials can effectively suppress hydrogen permeation as the lining of high-pressure hydrogen storage tanks, increasing the hydrogen storage density to 5.7 wt%, approaching the 2025 target of the US Department of Energy. In addition, it can also be used as a thickener for proton exchange membranes in fuel cells, enhancing the mechanical strength and chemical stability of the membrane. Market forecast shows that by 2030, the demand for hydrated silica in the new energy sector will account for 15% of the global total, becoming a new growth pole in the industry.
