Battery electrolyte used for anti-oxidation cycle of battery car

Abstract

The invention discloses a battery electrolyte used for anti-oxidation cycle of a battery car, composed of the following components in parts by weight: 60-90 parts of sulfuric acid aqueous solution, 4-15 parts of vinylene carbonate, 9-14 parts of magnesium powder, and 10-20 parts of sodium sulfate, 4-9 parts of cobalt acetate, 9-18 parts of stannous sulfate, 7-10 parts of methylsulfonate, 10-16 parts of hydrogen sulfate, 11-15 parts of fumed silica, 4-10 parts of aluminum oxide, 4-11 parts of silane and 50-65 parts of deionized water. The battery electrolyte of the battery car provided by the invention is non-toxic and harmless with all performance indexes in compliance with environmental protection requirements as well as simple and easy use process, is capable of improving the charge acceptance of the battery and improving the capacity and cycle life of the battery, and is wide in application field and low in cost.

Description

technical field [0001] The invention relates to the field of development and utilization of battery cars, in particular to an anti-oxidation cycle use battery electrolyte for battery cars. Background technique [0002] In the development of the field of battery vehicles, batteries are now widely used because of their low price and mature technology. Although many new batteries have begun to appear, lead-acid batteries still have an irreplaceable position in many fields. The five major components of a lead-acid battery are the positive electrode, the negative electrode, the diaphragm, the electrolyte, and the battery case, among which the electrolyte is one of the main factors affecting battery performance. There are many problems in existing batteries. The battery loses water too quickly, and the electrolyte dries up and bulges and deforms. In addition, the capacity of the battery drops sharply in the low-temperature season, and the amount of charge is less than once, and th...

Problems solved by technology

There are many problems in existing batteries. The battery loses water too quickly, and the electrolyte dries up and bulges and deforms. In addition, the capacity of the battery drops sharply in the low temperature season, and the amount of charge is less than once, and the discharge will be less and less, which belongs to the charging and receiving capacity. Poor; the battery capacity is a bit low compared to the design capacity
