Which will explode in the near future in your opinion and why?
There’s about to be a huge break through in battery tech called solid state batteries. They’re already commercially available in small sizes. It’s only a matter of time before they’ve available in larger sizes suitable for EVs or for energy grid storage. They can charge super fast and don’t require elements that are awful for the environment like lithium ion batteries. It’s gonna be a game change for EVs. They can charge to 100% in the time it takes to fill a tank of gas.
