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.
Effects: Thickening, thixotropy, gel formation
