Lithium-ion batteries are rechargeable batteries that have high energy density, high open circuit voltage, high output power, no memory effect, low self-discharge, wide operating temperature range, and fast charging and discharging. They are commonly used in consumer electronics, military products, and aerospace products.
This document provides a comprehensive overview of lithium-ion batteries, explaining their operating mechanism based on lithium ion movement between electrodes. It details common cathode materials such as LiCoO2, LiMn2O4, LiNiO2, and LiFePO4, highlighting their respective characteristics and applications in consumer electronics, military, and automotive sectors.
