Abstract

The invention discloses a high-performance storage battery negative electrode lead paste for renewable energy storage, which comprises the following raw materials by weight: 81-82 parts of lead powder, 8-9.5 parts of 1.325 density dilute sulfuric acid, 7.3-8.5 parts of deionized water; 3-5 parts of sodium carboxymethylcellulose, 0.15-0.25 parts of barium sulfate, 0.12-0.22 parts of sodium lignosulphonate, 0.2-0.35 parts of humic acid, 0.1-0.2 parts of carbon black, 0.07-0.12 parts of short-staple, 0.002-0.005 parts of graphite alkene. The invention also provides a preparation method of the high-performance storage battery negative electrode lead paste for renewable energy storage. According to the invention, the charging receiving capacity of the negative plate is improved by adding graphene, the negative plate conversion environment is improved, and the problem that the negative plate cannot be converted due to the generation of coarse lead sulfate crystal particles on the surface ofthe negative plate is avoided, so that the service life of the battery is prolonged, the development requirement is met, and the negative plate is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of battery preparation, in particular to a high-performance battery negative lead paste for renewable energy storage and a preparation method thereof. Background technique [0002] A storage battery is a device that directly converts chemical energy into electrical energy. It is a battery designed to be rechargeable. It is recharged through a reversible chemical reaction. It usually refers to a lead-acid battery, which is a type of battery. , belonging to the secondary battery. Its working principle: when charging, the external electric energy is used to regenerate the internal active material, the electric energy is stored as chemical energy, and the chemical energy is converted into electric energy output again when it needs to be discharged. [0003] The outdoor communication battery is one of the batteries. Due to the use environment, the outdoor communication battery will have the problem of vulcanizat...
