[0032] For an implementation, see figure 1 , a preparation process of a novel button cell, comprising the following steps:
[0033] S110. Providing a cell assembly, which includes a cell body, a positive tab, and a negative tab.
[0034] It should be noted that the cell assembly is the component for storing electric energy of the new button battery, wherein the electric energy is stored in the cell main body, which can be a wound type cell body or a laminated cell body. According to the specific production needs, a suitable preparation process for the main body of the battery cell can be adopted. The positive pole tab and the negative pole tab are used as the electrodes of the new button battery to transmit the electric energy in the main body of the battery cell to the external electrical device. When using the new button When the battery is used, the new button battery is connected to the external electrical device, the positive tab and the negative tab can output the elect...
