187 Lithium-ion battery is popular type of rechargeable battery commonly used in portable electronics, electric vehicles, and many other applications. They offer a good balance of energy density, power density, and longevity. Here’s a detailed look at the structure and working principle of lithium-ion battery: Table of Contents Structure of Lithium-Ion BatteryWorking Principle of Lithium-Ion BatteryDischargingKey Features and Benefits Structure of Lithium-Ion Battery Electrodes: Lithium-ion battery consist of two main electrodes: Cathode (Positive Electrode): Typically made from lithium metal oxides such as lithium cobalt oxide (LiCoO2) or lithium iron phosphate (LiFePO4). The cathode is where lithium ions are stored. Anode (Negative Electrode): Commonly made from graphite. The anode stores the lithium ions when they move from the cathode during charging. Electrolyte: A lithium salt in an organic solvent. The electrolyte facilitates the movement of lithium ions between the cathode and anode during charging and discharging. Separator: A porous membrane that separates the cathode and anode. It prevents direct electrical contact between the electrodes while allowing the passage of lithium ions. Current Collectors: These are conductive materials that allow current to enter and leave the cell. The anode typically uses copper, while the cathode uses aluminum. Working Principle of Lithium-Ion Battery The operation of lithium-ion battery revolves around the movement of lithium ions between the cathode and anode through the electrolyte, a process linked with electron flow in the external circuit. Charging Lithium ions move from the cathode to the anode: When lithium-ion battery charges, lithium ions are released from the cathode and move through the electrolyte to the anode. Electrons flow from the cathode to the anode via the external circuit: This movement of electrons generates an electric current that can be used to power external devices or store energy. Discharging Lithium ions move from the anode to the cathode: During discharge (when the device is being powered), lithium ions move back from the anode through the electrolyte to the cathode. Electrons flow through the external circuit from the anode to the cathode: As electrons flow through the external circuit, they provide electrical energy to the device being powered. Key Features and Benefits High Energy Density: Lithium-ion battery can store a large amount of energy in a small volume, making them ideal for portable electronics. Low Self-discharge: These battery lose their charge very slowly when not in use. No Memory Effect: They do not suffer from the memory effect (a condition which causes battery to hold less charge over time), allowing them to be charged and discharged repeatedly without a decrease in capacity. The combination of these structures and mechanisms allows lithium-ion battery to provide reliable, long-lasting power for a wide range of applications. 0 comment 1 FacebookTwitterPinterestEmail admin MarketGuest is an online webpage that provides business news, tech, telecom, digital marketing, auto news, and website reviews around World. previous post Streamlining Construction Estimation: Best Practices for Accuracy and Efficiency next post How Does One Sophia Condo Handle Maintenance Requests?
