In a lithium-ion battery, the anode is made of graphite; in a lithium metal battery, it is made of lithium metal. Liquid electrolyte separates the anode and cathode. As the battery charges, positively charged lithium ions migrate from the cathode to the anode. When the lithium ions reach the anode, they lose their positive charge and form metallic lithium.
Pouch: A flexible, laminated foil that encases the internal components. This pouch is typically made from layers of aluminum and plastic, providing both protection and flexibility. The assembly process involves stacking the layers of the cathode, separator, and anode, injecting the electrolyte, and then sealing the pouch. This design allows for ...
