Very cool tech, but I expect you're all looking for the cold water:
"Nevertheless, practical applications require far more aggressive optimizations with the large-scale continuous fabrication of CNFs, tuning its surface porosity, and finally additives in the electrolyte to stabilize the system to achieve commercial-grade performance."
CNFs and CNTs are fucking expensive and difficult to acquire in bulk. A lot of exciting climate/energy techs require them, I hope somebody starts pumping them out at scale soon.
