A lithium-ion battery, or Li-ion, is a rechargeable battery that stores energy by moving lithium ions between its anode and cathode. It is commonly used in devices like smartphones and laptops. Major types include Lithium Cobalt Oxide and Lithium Iron Phosphate. These batteries are safe, efficient, and offer high energy and power density.
These batteries work through the movement of lithium ions between two electrodes, an anode and a cathode. During charging, lithium ions travel from the cathode to the anode. During discharging, they move back, releasing stored energy. This process occurs in an electrolyte, which allows ions to flow while preventing electron flow.
The characteristics of lithium-ion batteries, including energy density, cycle life, and safety, make them suitable for diverse applications. They power everything from portable devices to electric cars. Understanding these elements is essential as the world increasingly relies on efficient energy storage solutions.
