Progress of overseas companies in the field of solid-state batteries

Overseas, many companies have also made important progress in the field of solid-state batteries. For example, Maxell has developed a cylindrical all-solid-state battery, Enli Power and SoftBank have jointly developed an all-solid-state lithium metal battery using sulfide, Power Co has tested the Quantum Scape 24-layer solid-state battery A sample, Samsung SDI plans to develop and prepare for mass production of all-solid-state batteries with an energy density of 900Wh/L, Toyota Motors has clearly stated that it will mass-produce solid-state batteries in 2027 or 2028, and Solid Power has produced the first batch of solid-state battery A samples and delivered them to BMW.
