What are Lithium-Ion Batteries?
Rechargeable batteries using lithium ions as their main active ingredient are known as lithium-ion batteries. They are frequently utilized in electronic products and automobiles because they have a larger energy density than other kind of batteries, making them more effective and long-lasting.
How Lithium-Ion Batteries Work?
Lithium-ion batteries are made up of several components, including an anode, 陰極, and electrolyte. The cathode is often comprised of a metal oxide, whereas the anode is typically constructed of graphite. The electrolyte is a liquid or solid substance that helps to conduct the lithium ions between the anode and the cathode. When a lithium-ion battery is being charged, lithium ions go from the cathode to the anode through the electrolyte. Lithium ions flow from the anode to the cathode while the battery is in operation, producing an electrical charge that may be utilized to power a device.
