Abstract

The present invention relates to a lead-acid battery and its preparation method. It is characterized by that the additives of 2-benzimidazole sulfur and niacinamide, etc. are added in negative plate lead paste, the additives of oxyammonia sulfate, etc. are added in positive plate lead paste, the chemosynthsis liquor is added by stages, and its concentration is increased progressively, the additives of 6-aminopurine and 8-hydroxyquinoline-5-sulfoacid, etc. are added in chemosynthesis liquor,and the additives of acetyl acetanilide and aminobenzoic acid, etc. are added in chemosynthesis supplementing liquor, electrolytic liquor is formed from components A and B, the component A is sulfuric acid solution in which the additives of sulfanilamide, etc. are added, and the component B is SiO4 (4-) ionic silica sol solution in which the additives of tannic acid, sodium benzoate and sodium peroxide, etc. are added. Said battery features high specific energy, low electric consumption, long service life ,and applicable to various starting drawing, lighting, UPS and battery car, etc. as power supply.

Description

technical field [0001] Lead storage battery is a kind of chemical power supply, which is widely used in automobiles, diesel locomotives, ship communications, etc., as lighting, UPS, fixed, starting, and traction power supplies. Background technique [0002] At present, the existing lead-acid battery uses the positive electrode PbO 2 , negative electrode Pb, with dilute H 2 SO 4 As the electrolyte, the current collector and supporting grid are composed of alloys such as lead, antimony, cadmium, cobalt, calcium, strontium, copper, silver, platinum, ruthenium, osmium, arsenic, selenium, tellurium, and sulfur. The disadvantage is that the concentration polarization, electrochemical polarization, and resistance polarization produced by the electrolyte on the electrode lead to passivation, decay, rapid capacity reduction, short life, fast self-discharge, low charge retention capacity, and large internal resistance. , The charging potential is high and t...
