AEROSIL® fumed silica for battery gels


Gelling / Thickening of sulphuric acid for accumulators with AEROSIL® fumed silica.


AEROSIL® 200 or its densified version, AEROSIL® 200 V, are used in special lead acid batteries to gel the electrolyte (i.e. very strong thickening).

Major benefits of using AEROSIL® 200 and AEROSIL® 200 V, respectively, are:

  • significant increase of accumulator's service life by prevention of acid stratification even at deep discharge

  • improvement of resistance to extreme temperatures, shock and vibration

  • leak proof battery even if not mounted in an upright position

Gel batteries made with AEROSIL® fumed silica require no maintenance with respect to watering and can be used as deep-cycle batteries. These properties make them an excellent choice for applications like forklifts, boats, storage of green energy and back-up power supply for example alarm systems and telecommunication.
