Expanded metal in batteries

Expanded metal is mainly used in a battery as a separator between the various components. The separator separates the positive and negative electrodes to prevent an electrical short circuit, while at the same time enabling ion transport for the electrochemical reaction.

Expanded metal provides high mechanical stability to hold the electrodes in place while allowing free movement of ions within the battery. This enables an effective reaction of the electrode materials and improves the performance of the battery.

In addition, the expanded metal can also act as a current conductor and help to distribute the current over the surface of the electrode. This helps to reduce the internal resistance of the battery and increase the discharge and charging efficiency.
