In the chart from the article I see that capacitors are shown as having high specific power. Would it not work to use a hybrid approach of capacitors for takeoff and then Li-ion for most of the flight? I know it would make the system more complicated and therefore more expensive up front, but I wonder if it's an option or if it's out of the question for one reason or another. I've read that supercapacitors are being used for busses and other applications. https://en.wikipedia.org/wiki/Supercapacitor https://en.wikipedia.org/wiki/Supercapacitor
- fw_double_e 7y agoCapacitors are great for high load requirements but not great as an energy storage device. i.e. if you wanted to draw several hundred amps for a second or two with relatively low heat waste, an ultra-capacitor arrangement would be the way to go, but for energy storage, a battery wins hands down. There's huge research going into expanding the capacity of capacitors. Check out this video about capacitors: https://www.youtube.com/watch?v=EoWMF3VkI6U https://www.youtube.com/watch?v=EoWMF3VkI6U
