Toyota announced this week that it had signed a joint agreement with fellow Japanese company Sumitomo Metal Mining with a view to mass produce the cathode materials required for all-solid-state batteries (SSBs).
Unlike the current battery technology powering most EVs, which uses a liquid as the electrolyte, solid state technology replaces this liquid with a solid material, offering the potential for smaller size, higher output, faster charging speeds and a longer life. The technology's potential is undoubtedly exciting, but will Toyota really be first?
