Toyota teases 745‑mile solid state
Toyota is being cited for a bold solid‑state battery claim that could enable roughly a 745‑mile range using solid electrolytes — a potential step‑change for EV range if it scales. The post frames this as a major breakthrough in battery tech, though real‑world production timelines remain the key question. (x.com)
The statement originated with Keiji Kaita, president of Toyota’s research and development center for carbon neutrality, who described the development as a “technological breakthrough” in a July 2023 briefing. (world-energy.org) Toyota told journalists it aims to move to mass production of all‑solid‑state cells in the 2027–2028 timeframe and has been developing the technology at its Teiho facility in Toyota City. (autonews.com) The automaker has signed a commercial partnership with Idemitsu Kosan to develop sulfide solid electrolytes and to build a supply chain and manufacturing process for full‑scale production. (autonews.com) Company materials and executive comments say the recent work focused on simplifying the electrolyte manufacturing process and on fixing durability problems Toyota traced back roughly three years. (batteryindustry.net) Toyota’s public roadmap presented to reporters describes two planned solid‑state cell variants: an initial model targeted for the 2027–28 window and a follow‑on, higher‑density cell to arrive later. (autonews.com) Industry observers have repeatedly cautioned that laboratory “breakthroughs” frequently encounter scaling and manufacturing hurdles before reaching automotive mass production. (mining.com) While advancing solid‑state work, Toyota is also pursuing incremental improvements to conventional prismatic cells, with media reporting interim performance targets for those cells by 2026.
