Abstract

The invention relates to a formed lead storage battery for starting, and belongs to the technical field of lead storage batteries. According to the formed lead storage battery for starting, an anode adopts active lead dioxide of a lead-antimony matrix to form an electrode, a cathode adopts active lead of a lead-calcium-tin-aluminum alloy matrix to form an electrode, electrolyte is sulfuric acid electrolyte containing cobalt ions and silver ions, and a thin glass felt partition plate is used. The invention provides a formed lead storage battery for starting, which has the electrochemical characteristics of a common lead-acid battery and particularly has the characteristic of high power, and meanwhile, compared with a traditional starting battery manufacturing process, the working procedures of lead powder preparation, lead paste preparation, plate coating, curing and formation are canceled, the equipment investment is reduced, and the production cost is reduced. And the carbon emission in the production process of the traditional automobile starting battery is greatly reduced.

Description

technical field [0001] The invention relates to a formable lead storage battery for starting, belonging to the technical field of lead storage batteries. Background technique [0002] Lead-acid batteries were first invented by Gaston planté in 1859 and have a history of more than 160 years. He rolled two lead sheets into a cylindrical shape, separated them with a cloth, used a 10% sulfuric acid solution as the electrolyte, and then charged it with a dry battery to form a battery with a voltage of about 2V. This kind of battery is characterized by good reversibility, that is, the conversion from chemical energy to electrical energy can almost be carried out in the opposite direction to store electrical energy. This kind of battery is an unpasted lead-acid battery. [0003] However, the specific energy of the planté battery is still very low after the improvement. With the popularity of pasted plates, formable batteries were gradually forgotten. Compared with the pasted typ...
