The lightbulb was one invention, but what changed the world, was the lightbulb making machine. So a style of battery that can be manufactured with high speed, efficiency and low waste. Some solid state battery technologies promise this. Potentially a lot easier to make. Solventless dry electrode are some keywords. On the other hand, regular li-ion is already quite scaled, proven and entrenched, so maybe the solution turns out to be incremental changes to those processes. Multiple companies have tried to leapfrog to solid state but have canceled or delayed their plans. With large scale mass production, don't underestimate the power of path dependency. These supply chains and manufacturing methods have inertia. New financial methods probably will also happen with personal cars, as the investment cost goes up but running and maintenance down. Also alternative ways to move around. Taxis, scooters, robotaxis - all make more sense with electrics. Maybe some tunnels for electric vehicles. They're building light rail a lot in my country, and new Chinese electric buses have started to appear en masse. Air quality should improve a lot. If you think about, is buying a car with a huge battery good for the environment? Maybe instead of mostly sitting on the driveway, those batteries could have been applied to supplanting diesel in an electric bus. Or coal or gas in a grid storage system, together with solar and wind.
