In 2023, China accounted for 35% of global fumed silica production capacity (up from just 12% in 2018), with exports of high-end products surging by 87% year-on-year. The domestic products are priced at only 60% of imported equivalents while achieving a specific surface area of 400±15 m²/g, comparable to Evonik's AEROSIL®380.

In the new energy sector, adding 0.5% modified fumed silica to lithium battery separator coatings can increase cycle life by 40% (CATL 2023 data).

Key highlights:
• China's rapid capacity expansion (35% global share in 2023 vs 12% in 2018)
• Competitive pricing at 60% of import costs with matching quality
• Significant 40% battery life improvement in EV applications
