(May 9, 2026) With the rapid development of domestic new energy vehicles, photovoltaic energy storage, and lithium battery material industries, silica is breaking through the traditional filling field and deeply cutting into the supporting system of the whole new energy industry chain, becoming a key new material with great growth potential in the field of fine chemicals.

In the field of new energy vehicles, high-dispersion silica is the core raw material of green tires, which can effectively reduce tire rolling resistance, improve vehicle endurance, and adapt to the development trend of lightweight and energy-saving new energy vehicles.

Modified silica is widely used in photovoltaic films, sealants, energy storage battery separators, packaging materials and other links with its excellent insulation, thickening, reinforcement and anti-aging properties, and is suitable for the long-term outdoor weathering requirements of photovoltaic modules and energy storage power stations.

In terms of lithium battery support, nano-scale silica is used in electrolyte additives, separator coatings, pole piece reinforcement and other scenarios, playing a role in adsorption, anti-precipitation of lithium, and improving stability.

Compared with the traditional civil field, the new energy track has strict requirements for the purity, particle size uniformity, and surface modification performance of silica, with higher thresholds and greater premium space. At present, a number of domestic chemical enterprises are developing special grades of silica for new energy to achieve performance benchmarking of imported products, and gradually break the monopoly pattern of foreign brands.

Industry institutions predict that in the future, new energy will become the first growth curve of silica, and the development logic of the industry will shift from traditional building materials and rubber rigid demand to high-end new energy and new material support.
