Silica-loaded glass mat SLGM

figures in brackets represent percentage of initial thickness at 10 kPa. Contraction = (dry thickness - acid-saturated thickness)/dry thickness x 100%. 

In another ALABC project [31], a so-called Silica Powder AGM composed of 70wt.% siliea, lOwt.% polyester fibres (with low melting point and acting as a binder) and 20wt.% glass fibres was subjected to cycling tests to 72% DoD. The initial pressure was 42kPa and the cell achieved about 250 cycles before its capacity fell below 80% of the initial value. 

Within the framework of a project for the optimization of batteries for storing photovoltaic and wind energy, an AGM separator with an inorganic filler of high surface-area was developed. The surface area was found to increase and the pore size to decrease significantly with incorporation of the filler, but the tensile strength suffered, see Table 7.13 [32]. With this separator (regardless of how much filler was 

Other AGM modifications. Some recently published patents have described AGM separators produced from dry-laid instead of wet-laid fibres
