Towards real Li-air batteries: A binder-free cathode with high electrochemical performance in CO2 and O2

A binder-free cathode with high electrochemical performance in CO2 and O2 was prepared on Ni foam via a simple floating catalyst chemical vapour deposition method. The N-doped carbon nanotubes show enhanced performance in Li-CO2 batteries. Which is a good candidate for future Li-air batteries.184
