Artificial Solid‐Electrolyte Interphase and Bamboo‐like N‐doped Carbon Nanotube Enabled Highly Rechargeable K‐CO2 Batteries (Adv. Funct. Mater. 2/2022)

Fiber-Shaped Electrodes In article number 2105029, Bin Wang and co-workers demonstrate highly rechargeable K-CO2 batteries are with bamboo-like N-doped carbon nanotube cathodes and pre-protected K anodes decorated with an artificial solid electrolyte interphase film. The synergistic effect of efficient cathodes and durable anodes guarantees K-CO2 batteries long cycle-life, high specific capacity, and good rate capability.
