Secondary Voltaic Cells
What is Secondary Voltaic Cells?
Secondary voltaic cells (rechargeable batteries) are electrochemical cells that can be recharged by passing an electric current through them in the reverse direction, reversing the electrode reactions and restoring the original reactants. Common examples include lead-acid batteries, nickel-cadmium (NiCad), nickel-metal hydride (NiMH), and lithium-ion cells. Secondary cells are used wherever a reusable, long-life power source is required, such as in portable electronics, electric vehicles, and grid energy storage.
