Toyota launched the solid-state revolution, but Honda may finish it. The Japanese automaker shocked the automotive world when it announced that it would actually begin producing solid-state EV batteries in January 2025. Despite years of research and literal billions of dollars, no company has yet managed to set up a production line and bolt a solid-state battery into a test car. If Honda lives up to its own promises, it will be the most groundbreaking event in the history EVs since a medium-sized California startup called “Tesla” announced that it would start producing electric cars.
