Solid-state batteries, renowned for their high energy density and enhanced safety, are poised to revolutionize multiple sectors including automotive, low-altitude aviation, and humanoid robotics. Presently, semi-solid-state batteries have already made inroads into the automotive industry, with their industrialization trajectory outpacing that of fully solid-state batteries. In sectors less sensitive to cost, the adoption of solid-state batteries is even more advanced. As their performance continues to soar and industrialization accelerates, solid-state batteries are anticipated to gradually permeate various fields, fostering widespread optimism about their developmental prospects.
