Environmentally-friendly washing agent for iron shell of lithium ion battery

Abstract

The invention provides an environment-friendly lithium-ion battery iron shell cleaning agent, which is made of the following raw materials in parts by weight: 1-5 parts of sodium lauryl polyether sulfate, 1-2 parts of butylene glycol, and sodium lauroamphoacetate 1-3 parts, 1-3 parts of disodium glycyrrhizinate, 1-2 parts of disodium EDTA. The environment-friendly lithium-ion battery iron shell cleaning agent of the invention has the characteristics of good cleaning effect, low consumption and environmental friendliness.

Description

technical field [0001] The invention relates to an environment-friendly lithium ion battery iron shell cleaning agent. Background technique [0002] With the further development of my country's economy, the demand for lithium-ion batteries has increased significantly, and at the same time, higher requirements have been put forward for the clean production of lithium-ion batteries. At present, more than half of lithium-ion batteries are packaged in iron shells. This type of packaging is conducive to large-scale industrial production, and the cost is more than 10% lower than that of soft packs. However, since the production process of iron shells requires mechanical stamping, it is inevitable to be contaminated with engine oil, dust, etc. dirt. Therefore, this kind of battery will clean the iron shell part before packaging. The traditional lithium-ion iron shell cleaning solution is compounded with a variety of surfactants. After the cleaning process, a large amount of waste...
