The negative electrode of lithium-ion batteries is made of carbon material, such as graphite. The positive electrode is a transition metal oxide containing lithium, while the negative electrode of lithium-ion batteries is made of carbon material, such as LiMn2O4. Electrolytes are organic solutions containing lithium salts. Usually, lithium-ion batteries do not contain metallic lithium. Currently, all solid state batteries are still in the research and development stage, and the technology is not yet mature. The main reason is that the different materials inside the positive electrode of the battery are difficult to perfectly match in terms of chemical and physical properties, resulting in various interface problems that affect the energy density and service life of the battery.
