Li–CO2 Batteries: Bamboo‐Like Nitrogen‐Doped Carbon Nanotube Forests as Durable Metal‐Free Catalysts for Self‐Powered Flexible Li–CO2 Batteries (Adv. Mater. 39/2019)

In article number 1903852, Jianli Cheng, Jun Lu, Bin Wang, and co-workers describe the fabrication of a fiber-shaped self-powered Li–CO2 battery based on bamboo-like N-doped carbon nanotube fibers working as the cathode for the Li–CO2 battery and the counter electrode for the dye-sensitized solar cells simultaneously; they demonstrate high energy-conversion efficiency, long cycle life, good stability, and flexibility.
