Embodiment Construction

[0016] Specific embodiments of the present invention will be described in detail below.

[0017] The ratio of each material in the electrolyte:

[0018]

[0019] Option 1: Due to the small space in the battery design, in order to ensure sufficient lead, the only solution is to reduce the electrolyte space, and the amount of electrolyte determines the performance of the battery; when the battery is used in a high temperature environment, the battery loses water quickly. The reason for this is to minimize the loss of water in the electrolyte formula, and it is better to add CMC to the upper limit.

[0020] Solution 2: The battery is used for a long time under the condition of over-discharge, and the charging is not timely, and it is easy to generate large particles of lead sulfate; the battery is used in a low-temperature environment, and the negative plate is easy to over-discharge and generate a large amount of lead sulfate, which is not easy to convert into active substanc...

Abstract

The invention relates to an electrolyte solution, and especially relates to a lead-acid storage battery electrolyte solution and a preparation method thereof. The lead-acid storage battery electrolyte solution is characterized by being prepared from 0.5-2 g of sodium carboxymethyl cellulose, 1-2 g of sodium polyaspartate, 1-2 g of sodium tetraborate, 0.1-0.5 g of stannous sulfate, 32-36 g of sulfuric acid and 58-65 g of pure water. The invention aims to provide the lead-acid storage battery electrolyte solution and the preparation method thereof, and solves the problem of short service life of a storage battery.

Description

technical field [0001] The invention relates to an electrolyte, in particular to an electrolyte for a lead-acid storage battery and a preparation method thereof. Background technique [0002] At present, short battery life is a major problem in the industry, but the following phenomena of short battery life are directly related to the preparation of electrolyte, such as: the battery loses water too quickly, and the electrolyte bulges and deforms after it dries up; the battery is deep The particles of lead sulfate after discharge are particularly large, and lead sulfate cannot be converted into active substances after charging; the capacity of the battery drops sharply in low temperature seasons; the interface resistance between the grid and the lead paste is large, and the mutual bonding between the lead paste and the lead paste is poor and finally loose Falling off; the battery charge is less than once, and the discharge will be less and less, which belongs to the poor char...
