Technical Information 1412: AEROSIL® fumed silica in gel lead acid batteries  (pdf, 8.83 MB)

The Technical Information 1412 provides an overview about the use of AEROSIL® for gelification and therefore immobilization of sulfuric acid to increase life time of gel batteries. This brochure gives a deeper insight into the topics: fumed silica, gelling process of sulfuric acid, and electrochemical performance. These information are of importance, especially for gel battery manufacturer to find the right process conditions for incorporation of AEROSIL® into sulfuric acid. In addition, the differences of gels made from AEROSIL® fumed silica and silica sol are compared with each other and their influence on the final battery performance are discussed.
