PURPOSE:To prevent short circuit caused by piercing a separator in the in- container formation of a non-charged battery by adding ammonium sulfate to an electrolyte. CONSTITUTION:Ammonium sulfate is added to an electrolyte, and in-container formation is conducted. For example, a battery using electrolyte containing 3-5g/l (NH4)2SO4 has a PbO2 content of 80% or more and the 5hR capacity is similar ...

PURPOSE:To prevent short circuit caused by piercing a separator in the in- container formation of a non-charged battery by adding tin ions to an electrolyte. CONSTITUTION:Tin ions are contained in an electrolyte, and in-contaier formation is conducted. For example, a battery using electrolyte containing 3-5g/l SnSO4 has a PbO2 content of 80% or more and the 5hR capacity is similar to the rated cap...

PURPOSE:To prevent short circuit caused by piercing a separator in the in- container formation of a non-charged battery by containing 30 mg/l aluminium ion in an electrolyte. CONSTITUTION:30 mg/l aluminium ion is contained in an electrolyte, and in- container formation is conducted. For example, a battery using electrolyte containing 5-7 g/l Al2(SO4)3 (30-40 mg aluminium ion/l) has a PbO2 content ...

PURPOSE:To prevent short circuit caused by piercing a separator in the in- container formation of a non-charged battery by containing 30 mg/l or more beryllium ion or 60 mg/l or more magnesium ion in an electrolyte. CONSTITUTION:30 mg/l or more beryllium ion or 60 mg/l magnesium ion is contained in an electrolyte, and in-container formation is conducted. For example, a battery using electrolyte co...

PURPOSE:To increase the cycle performance of a lead-acid battery by pouring low specific gravity sulfuric acid containing stannous ion in a non-charged battery using a lead-calcium based alloy grid, conducting in-container formation, and replacing the low specific gravity sulfuric acid with high specific gravity sulfuric acid containing stannous ion, then adjusting the specific gravity of the elec...

PURPOSE:To make absorb the moisture in positive and negative plates and a separator to prevent the generation of a lower oxide by placing an inorganic carbonate such as Na2CO3 between the supports, located under a plate group, of a container. CONSTITUTION:An inorganic carbonate is placed between the supports, located under a plate group, of a container. For example, a bag in which tablets, particl...

PURPOSE:To substantially improve charging-recoverableness of an enclosed type lead storage cell after being preserved over a long period by comprising a ground of positive and negative plates and a separator, where the pore diameter of an active material an the surface layer of a plate is larger than that of the material in the plate. CONSTITUTION:A group of plates comprises positive and negative ...

PURPOSE:To make it possible to minimize a difference between high and low specific gravity of electrolyte by providing a group of plates comprising hollow spaces without any active material filled therein sections of a plate divided into a plurality in its vertical direction and supports of electrolyte made of glass fibers at the sections, where an active material is filled, of a plate connected t...
