Lithium-ion battery refers to a secondary battery system in which two different lithium intercalation compounds that can reversibly intercalate and deintercalation lithium ions are used as the battery's positive electrode and negative electrode, resp…
Lithium-ion batteries are divided into liquid lithium-ion batteries and polymer lithium-ion batteries. The electrolyte of lithium-ion batteries is fluid, so they are more unstable than lithium-polymer batteries, and they may explode if they are beat…
The actual negative electrode materials used in lithium-ion batteries are basically carbon materials, such as artificial graphite, natural graphite, mesocarbon microspheres, petroleum coke, carbon fiber, pyrolysis resin carbon, etc.…
