The production process of lithium batteries for electric bicycles includes the following steps:

1.Prepare raw materials, including positive and negative materials, electrolyte, separator, etc.

2.Prepare electrode slurry by mixing positive and negative materials, binder, solvent, etc.

3.Coating: coat the electrode slurry onto the collector (aluminum foil or copper foil) with a specified thickness and then dry the solvent.

4.Slitting: cut the coated electrode into specified size and shape.

5.Stacking: stack positive and negative electrodes with separator in between to form a cell.

6.Assembly: put the cell into a battery box, add protection board and other components, and complete the assembly of the battery.

7.Test: test the assembled battery for voltage, current, capacity, etc. to ensure that the battery performance meets the requirements.

8.Packaging: package the tested batteries, apply labels and protective film, etc. to protect the batteries from damage.

9.Delivery: pack the packaged batteries and prepare for delivery.

The above is a general production process of lithium batteries for electric bicycles. The specific production process and flow may vary depending on different manufacturers and product types.
