摘要： PURPOSE:To lessen gas generation and decrease in the electrolytic solution and stabilize the characteristics by including organic compound having sulfo radicals in a liquid type lead acid storage battery, whose pos. electrode grating is made of Pb-Sb alloy. CONSTITUTION:A lead acid storage battery consists of two pos. electrodes 1 having grating made of Pb-Sb alloy, a neg. electrode 2 having a grating made of Pb-Ca alloy, two polyolefin series porous film separators 3 impregnated with naften type mineral oil which is sulfonized by SO2 gas, electrolytic solution 4 consisting of dilute sulfuric acid having a specific gravity of 1.26, and a battery jar 5. Organic compound having sulfo radical may be contained in any part of the battery, i.e., in the separator, electrode plate, or electrolyte, and has a nature of being adsorbed to the electrochemical active point on the electrolyte and hindering reactions. Therefore, gas generation and decrease in the electrolyte are lesser, and the characteristics are stabilized.

摘要： PURPOSE:To prolong the period of time taken before a short circuit occurs between electrode plates and/or between each electrode and a strap so as to prolong the life of a storage battery by forming a plurality of wires in such a manner that at least one of the wires has a cross section larger than those of the other wires. CONSTITUTION:A wire 11A whose cross section is made larger than that of each wire 11B is formed between the wires 11B of smaller cross section among a plurality of wires 11. When the wires 11B corrode and tend to expand, the wire 11A restrains this expansion and so an expanded grid does not expand in the direction of the wires 1B and the possibility of short circuits between the expanded grid and an anode strap or between the expanded grid and a strap is reduced. The life of the storage battery is thereby prolonged.

摘要： PURPOSE:To frame at the end of a mesh lattice when the mesh lattice is cut to a specified dimension by forming a non-machined part on the approximate diagonal line of the mesh lattice, and forming the meshes as approximately rectangular or parallelopiped. CONSTITUTION:A mesh lattice 1 includes an expanded mesh lattice part 2, non-machined part 3, and an electrode ear part 4 which is a current collector. The lattice part 2 constitutes a plurarity of meshes 2a and the non-machined part is located on the diagonal line of the lattice 1. In addition, an ear part 4 is provided at the tip of the electrode. When the lattice part 2 expanded at both ends of the non-machined part is cut to a specified dimension, the lattice is cut after the lattice part 2 is expanded so that the meshes 2a can be approximately rectangular, or parallelopiped. Therefore, a frame 5 is formed at the end of the lattice part after cutting. The forming of the frame 5 prevents meshes 2a having cut or protruding parts from being created at the end of the lattice part 2.
