Lithium ion batteries have the advantages of high energy, long life, high cost performance and less pollution, and are widely used in new energy vehicles, consumer electronics, energy storage and other fields. Lithium ion batteries are mainly divided into liquid and solid batteries. Liquid lithium batteries include liquid batteries, gel electrolyte batteries, and solid lithium batteries include semi-solid, quasi solid, and all solid batteries. Among them, semi-solid lithium batteries (with a solid electrolyte content of 90-95% in the cell) have achieved safety, energy density, and economy by reducing the liquid electrolyte content and increasing the solid electrolyte coating, and are now ready for mass production; The proportion of solid electrolyte in the battery cells of quasi solid state lithium batteries is further increased (the solid electrolyte content is usually above 95%), which is the stage of transition from sem…
