Japan has launched the first Toyota solid-state electric vehicles delivering 1,200-kilometre range on a single 10-minute charge.
The Toyota bZ5 Solid-State uses sulphide-based solid electrolyte cells achieving 400 watt-hours per kilogram energy density in a 100-kilowatt-hour battery module weighing 180 kilograms — less than half the weight of an equivalent-range lithium-ion system. The solid electrolyte enables safe charging at 400-kilowatt rates that would cause thermal runaway in liquid electrolyte batteries, delivering 10-minute charge time on Toyota's dedicated DC fast-charging network installed at.
The sulphide solid electrolyte operates at room temperature without any heating requirement — unlike oxide ceramic solid electrolytes requiring 60 degrees Celsius minimum operating temperature — providing reliable winter performance in Japan's northern regions and enabling confident export to Scandinavia, Canada, and Northern Europe where cold-weather battery degradation has historically limited EV adoption.
The 1,200-kilometre range combined with 10-minute recharging eliminates the two primary objections to electric vehicle adoption — range anxiety and charging inconvenience — simultaneously. Toyota has contracted solid-state cell production targeting 150,000 bZ5 units for the Japanese market in the first production year alone.
