1. In 2023, China accounted for 35% of global fumed silica production capacity (up from just 12% in 2018), with exports of high-end products increasing 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.

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