|Industry Information 2244: Products for batteries (pdf, 1,72 MB)
The world of rechargeable batteries is changing. For the last decades, lead acid starter batteries have been the most prominent type of battery on the market. But since the greenhouse effect and global warming are regarded as global threats and since energy costs are increasing significantly, scientists and technicians are looking for new energy concepts worldwide. Battery technology plays an important role in solving the current problems and in making energy available in a better way.
|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.
