Abstract:
Metal-gas batteries that remove CO gases would provide enormous environmental benefits. We report here Na-CO batteries using the combination of a sodium anode and a binder-free multiwall carbon nanotube cathode with a CO reactant. The constructed Na-CO batteries show a high discharge capacity of 8000 mA h g-1 based on the mass of carbon nanotubes (corresponding to ∼865.9 W h kg-1 based on the mass of total active materials) and a stable cycling of 70 cycles with an increased gap of only 3.7 mV. This work offers a promising strategy for efficient utilization of CO to generate electricity through an electrochemical conversion method.

Charging Conductors By Induction
Generally, conductors like metals do not allow any excess charge to be present on them. Any excess charge added to metals easily flows away, for example, when a metal is placed on the Earth. This process is called earthing.
However, conductors can be charged by a process called induction. For example, consider charging a...
