GEL battery also known as colloidal sealed lead-acid batteries , is a VRLA battery ( a total of two kinds ) , the use of colloidal electrolyte , ie GEL technology to Germany sunshine behalf of the company. Another VRLA batteries using AGM separators, namely AGM technology , with some Japanese companies represented. Both have advantages and disadvantages , communication , development of AGM-VRLA batteries power the rapid development of the last century , high market share is relatively low GEL-VRLA batteries.
Colloidal sealed lead-acid batteries ( GEL batteries ) , which is composed of silica sol and sulfuric acid electrolyte is dubbed , the concentration of sulfuric acid solution is lower than AGM batteries , typically 1.26--1.28g / cm3. Amount of electrolyte AGM batteries to more than 20% , with quite a flooded battery . This state exists colloidal electrolyte filled in the separator between the positive and negative electrode gel surrounded by a sulfuric acid electrolyte , the battery does not flow out . Because of this battery is flooded Noncompact assembly structure , positive grid low antimony alloy material can also be used tubular battery cathode plate . Meanwhile, in order to improve the battery capacity without reducing battery life, the plates can be made thinner . The internal space of the battery compartment can also broaden few .
Its advantages are as follows : GEL type gel batteries is no free electrolyte gel electro-hydraulic rear chances leak acid battery is much smaller than the former ; its perfusion more than 10 - 15 % sulfuric acid , water loss and less so gel batteries will not cause failure due to dehydration ; colloidal poured increase in the strength of the separator to protect the plate , make up the clapboard case of acid contraction defect , the assembling pressure reduction is not obvious reason for having extended battery life one ; colloid filled voids between the plates and separators , reducing the internal resistance of the battery , the charge acceptance may thus be improved . So gel battery overdischarge , Shaanxi multiplexing capability and low temperature charge-discharge performance is superior than AGM batteries; gel battery consistency than similar AGM type battery much better.
Domestic production has been colloid following four : gas gum , silica sol , mixed sol , silicone polymer gel .
