| description | The invention discloses a manufacturing method of a battery cell top cover, which sequentially comprises a shape forming step, an injection molding pretreatment step and an injection molding step, and the injection molding pretreatment step comprises the following steps: step 1, degreasing treatment, step 2, sanding treatment, step 3, alkali washing treatment, step 4, electrolytic treatment, and step 5, hole deposition treatment. The injection molding step comprises preheating treatment and injection molding, and first molding and second molding are performed after preheating to obtain the battery cell top cover. Compared with the prior art, the injection molding parts can be bonded together besides adopting concave-convex nano-pore structures, and the bonded bonding surface is a rough surface, so that the combination degree of the whole injection molding part with the pole and the smooth aluminum sheet is greatly improved, and the test shows that the binding force reaches about 3000N which is far higher than |
