March 2013A typical coin cell comprises of a pair of casings (one distinctly marked with positive sign) and a spacer disc (the spring can be optional). An electrochemical cell is assembled in one casing (negative pole) and the spacers are placed in between the cathode and the other casing (positive pole). Thereafter, the cell is mounted on the suitable die and hydraulically pressed. Furthermore, a hermetically sealed coin cell can be realized for further electrochemical characterization. Similarly, using another pair of specially designed die-plungers the cell can be un-crimped. Electro-active materials collected from such un-crimped cell are intact for further analysis. However coin cell casings cannot be reused. Thus, the ‘Electric crimper machine’ is highly reliable in instant fabrication and post-mortem of an electrochemical cell.
