Could be interesting, though it's a few years down the road. I could see Tesla being the first to try and adapt this technology to EVs, but I think it would fit a niche. Because capacitors bleed power, they wouldn't be a good choice for normal driving. However, if you had a 100 kWh module that you could drop in and charge to near 100% capacity at, say, 400 kW, it would make an excellent option for long-distance driving.
Outside of improving batteries (size and charge rates), a few options already exist:
- Battery swaps
- Single-use air batteries
- Liquid redox batteries that can flush the system with recharged fluid
Only time will tell which solution is best.
