Problems solved by technology

Although the plastic case battery brings great convenience to battery capacity design and popularization and application, due to the relatively poor thermal conductivity of the plastic case, a certain amount of heat will be generated during the charging and discharging process. The environment is relatively complex
Although it will not lead to major problems with the safety of the battery, there are certain potential safety hazards after all.

Abstract

The invention discloses a special ABS modifying method for a power battery shell. The method comprises the following steps of: dosing, cleaning, grinding, crystallizing and drying, premixing, mixed melting and high-pressure extrusion moulding to obtain a shell. In the invention, polyvinyl cyclic silane and graphene microchips are added as new functional auxiliaries for promoting polymer crystallization and improving the grain structure thereof, the heterogeneous nucleation of polymer can be realized, the rigidity, wear resistance and processability of the material are improved, the mechanical properties are better, and the influence on the crystallization and orientation behaviors of macromolecules is stronger than that of other materials. In the invention, through innovation of the raw material mixing and processing technology, the plasticity and compression strength of the shell are greatly improved, and the shell has perfect thermal conduction, insulating and flame-retardant effects and high safety and stability.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a special ABS modification method for power battery casings. Background technique [0002] At present, power batteries are mainly classified according to their shells, such as steel shells, aluminum shells, flexible packaging and plastic shells. Plastic case batteries are more suitable for large electric tools. The capacity of the battery can be designed according to the needs. The application prospect of the battery is very wide. At present, it has great advantages in the application of battery cars and electric motorcycles. The starting point of the research is relatively late. At present, plastic cases with PP as the base material are mostly used in the market. Although the plastic case battery brings great convenience to battery capacity design and popularization and application, due to the relatively poor thermal conductivity of the plastic case, a certain amount of heat w...
