Lithium ion batteries are a type of secondary battery (rechargeable battery) that primarily relies on the movement of lithium ions between the positive and negative electrodes for operation. During the charging and discharging process, Li+is intercalated and disembedded back and forth between the two electrodes: during charging, Li+is disembedded from the positive electrode, embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium rich state; When discharging, the opposite is true. On October 9, 2019, the Royal Swedish Academy of Sciences announced that the 2019 Nobel Prize in Chemistry would be awarded to John Gudinav, Stanley Whittingham, and Yoshino Akira in recognition of their contributions in the development of lithium-ion batteries. Lithium batteries are divided into lithium batteries and lithium-ion batteries. Both mobile phones and laptops use lithium-ion batteries, commonly known as lithium batteries. Batteries generally use materials containing lithium as electrodes, which are representative of modern high-performance batteries. However, real lithium batteries are rarely used in daily electronic products due to their high risk. Lithium ion batteries were first successfully developed by Sony Corporation of Japan in 1990. It involves embedding lithium ions into carbon (petroleum coke and graphite) to form a negative electrode (traditional lithium batteries use lithium or lithium alloys as the negative electrode). LixCoO2 is commonly used as the positive electrode material, as well as LixNiO2 and LixMnO4. The electrolyte uses LiPF6+ethylene carbonate (EC)+dimethyl carbonate (DMC). Petroleum coke and graphite as negative electrode materials are non-toxic and have sufficient resources. Lithium ions are embedded in carbon, overcoming the high activity of lithium and solving the safety problems of traditional lithium batteries. The positive electrode LixCoO2 can achieve high levels of charging and discharging performance and lifespan, reducing costs. In short, the comprehensive performance of lithium-ion batteries has been improved. It is expected that lithium-ion batteries will occupy a large market in the 21st century
