Coin cell or button battery assembly tutorial and common problem analysis
**I. Coin Cell Assembly Tutorial** 1. In a coin half-cell with metallic lithium as the negative electrode, the negative electrode material in a full cell actually serves as the positive electrode in the coin cell. In the coin cell, it is necessary to ensure that the diameter of the separator > the diameter of the lithium disc > the diameter of the electrode. When moving the entire coin cell with tweezers, insulated tweezers should be used to prevent short-circuiting between the positive and negative electrodes. 2. To ensure the accuracy of subsequent electrochemical testing and to account for errors and operational mistakes, the number of coin cells or simulated cells
