Preparation of negative electrodes: coating materials such as lithium metal or graphite on conductive materials and stacking them with polymer electrolyte layers. Electrolyte injection: injecting polymer electrolyte solution or gel between the positive and negative electrodes to form an electrolyte layer, while ensuring that there is a good conductivity channel between the positive and negative electrodes. Coating and packaging: stacking the positive and negative electrodes together, and then coating them with materials such as polymer films or aluminum foil to form the positive and negative electrode structure of the battery.
