CATL aims to produce solid-state batteries in small quantities by 2027 for the first time. Meanwhile, a company representative describes large-scale production as “still challenging.” This marks the first-ever timetable for the introduction of solid-state batteries by the worldʼs largest manufacturer of electric vehicle batteries. According to CATL, the technologyʼs and productionʼs current maturity level is at 4 on a scale of 1 to 9 and is expected to reach 7 to 8 by 2027. Solid-state batteries have significant potential, particularly in terms of energy density, which is expected to reach 500 watt-hours per kilogram as opposed to current liquid-electrolyte lithium-ion batteries which reach their limit at 350 watt-hours per kilogram.
