Abstract

The invention provides colloidal electrolyte for a starting type battery, which comprises the following components by mass percent: 36 to 45 percent of sulfuric acid, 45 to 56 percent of purified water, 7 to 12 percent of JN-30 gelata, 0.055 to 0.15 percent of stannous sulfate, 0.055 to 0.14 percent of aluminium sesquioxide, 0.055 to 0.14 percent of sodium salt of carboxy methyl-cellulose, 0.055 to 0.2 percent of zinc sulfate, 0.0055 to 0.02 percent bismuth trioxide, and 0.55 to 1.0 percent of phosphoric acid. The colloidal electrolyte is better in runnability before being added into the battery, after being added into the battery, the colloidal electrolyte is changed to be non-liquid jelly type gel through electrolysis, water loss is avoided, the problem of removed power deposition in conventional electrolyte caused by rocking and impacts of heavy current can be solved, and the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a colloidal electrolyte for starting batteries. Background technique [0002] Ordinary starting battery grids are made of lead-antimony alloys. One of the main disadvantages of lead-antimony alloys is the low hydrogen evolution potential. The battery will cause a large amount of electrolysis of water during charging. This is the loss of water due to water electrolysis, resulting in Environmental pollution and equipment corrosion. According to relevant information, the battery using lead-antimony alloy loses about 16-32 grams of water every 1,000 kilometers. In order to keep the electrolyte level between max and min, it must be checked once a month and must be checked frequently Add water for maintenance. Due to the back and forth shaking of the electrolyte and the impact of high current, the de-powdering phenomenon of the positive active material is accelerated, and it is deposited in ...
