High-density hybrid powercapacitors: A new frontier in the energy race

Hybrid "power capacitors" that can store as much energy as lithium batteries, but with much higher charge/discharge rates, a huge range of safe operating temperatures, super-long lifespans and no risk of explosion are already in production, says a small Belgian company that's been testing them and selling them for some time.
