Background
The new energy battery industry develops rapidly, and the research on the development current situation and the prospect of the new energy battery is the basis for promoting the development of the new energy industry. In recent years, under the era background of advocating green environmental protection, new energy batteries gradually enter the market, and the new energy battery industry matched with the new energy batteries also meets new development opportunities and receives more attention. A high efficiency power battery depends on two aspects, the battery system formulation and the degree of cleanliness of the power battery case. Two factors together determine the high energy density, service life and safety performance of the power battery. Battery system formulations can vary, but cleanliness of the battery case is a consistent requirement. In order to obtain a clean power battery shell, a series of operations such as oil removal, carbon deposition removal, aluminum scrap removal, chemical polishing and the like are carried out in the cleaning process, so that a high-quality power battery shell is obtained. According to the power battery shell, a thicker layer of stretching die oil, metal scraps (after laser cutting of a product, part of metal is attached to the surface and is not easy to fall), dust and other impurities cannot cause irreversible damage such as scratching, bruising, color change, deformation, performance change and the like to a workpiece in the cleaning process. The control of the process environment and the process parameters runs through the whole process of the power battery shell production, and the function of the cleaning process is more and more important along with the continuous change of the power battery processing process.
CN109694780A discloses an environment-friendly lithium battery shell hydrocarbon cleaning agent, which is characterized by comprising the following components: normal alkane solvent oil, a composite additive, a food grade alcohol ether solvent, a food grade monocyclic monoterpene solvent, halohydrocarbon and a dispersant. The environment-friendly carbon-hydrogen cleaning agent for the lithium battery shell, disclosed by the invention, has strong cleaning power and small smell, and can effectively clean metal powder on the surface of the lithium battery shell and prevent secondary pollution caused by secondary adsorption due to intermolecular force in the cleaning process.
CN113667991A discloses a new forms of energy aluminum battery shell deoiling deashing hydrocarbon cleaning agent and its preparation method, the new forms of energy aluminum battery shell deoiling deashing hydrocarbon cleaning agent composition includes: high-purity hydrocarbon solvent, modified alcohol ether solvent, ash remover, surface tension enhancer, aluminum brightening agent, penetrant and washing assistant. The hydrocarbon cleaning agent has good comprehensive performances of penetrability, detergency, solubilizing power, oil removal, ash removal, scale removal and the like.
Although the prior art has specially used cleaning agents for new energy battery shells, most of the cleaning agents are hydrocarbon cleaning agents, the cleaning agents have strong oil dirt dissolving effect, but have poor effect on removing aluminum scraps and the like, and the hydrocarbon cleaning agents belong to flammable or combustible cleaning agents and have great potential safety hazards. Therefore, in the art, it is desired to develop a water-based cleaning agent which is small in dosage, high in safety, free from corrosion risk, and strong in cleaning ability.

After the completion of the cleaning, the surface cleanliness of the battery case was checked using a german SITA surface cleanliness meter (10 points were taken, the diameter of each point measured was 1mm, and the average value of 10 points was measured).
The results are shown in Table 1.
TABLE 1
As can be seen from Table 1, the water-based cleaning agents prepared in the embodiments 1 to 3 have good cleaning effects on the new energy battery shell, the oil removal rate of the cleaned battery shell is more than 95%, the carbon removal rate of the cleaned battery shell is more than 95%, the removal rate of aluminum scraps is more than 90%, and the removal rate of ash is more than 95%.
Compared with the example 1, the water-based cleaning agent prepared in the example 4 has reduced removal rate of punching oil, carbon deposit, aluminum scraps and dust after cleaning the battery shell due to the lack of the auxiliary agent.
Compared with example 1, the water-based cleaning agent prepared in examples 5-6 has reduced removal rate of punching oil, carbon deposit, aluminum debris and dust after cleaning the battery shell because the mass ratio of the components of the emulsifier is not within the limited range of the invention.
Compared with the embodiment 1, the hydrocarbon cleaning agent in the comparative example 1 has a good effect of removing the punching oil and the carbon deposit, but has a poor effect of removing the aluminum scraps and the dust, cannot be diluted for use, and has high cost.
Compared with example 1, the water-based cleaning agent prepared in comparative examples 2-3 has obviously reduced removal rate of punching oil, carbon deposition, aluminum scraps and dust after cleaning the battery shell because of lack of accelerator or chelating agent.
Compared with example 1, in comparative examples 4-11, when the emulsifier is not the specific formula of the invention, the removal rate of the punching oil, carbon deposition, aluminum scraps and dust formation after the prepared water-based cleaning agent is used for cleaning the battery shell is reduced.
Compared with example 1, when the kind of the emulsifier in comparative example 12 is changed, the prepared cleaning agent has poor effect after being used for cleaning the battery case.
