Abstract Scope |
Aprotic lithium-air batteries (LABs) is an attracting alternative energy storage system in the future because of their high theoretical energy density. In aprotic LABs, electrochemical reactions involve the formation of lithium peroxide during the discharge and the recovery of it into oxygen and lithium ion during the subsequent charge. The capacity of LABs largely depends on the ability of the cathode to store the lithium peroxide without hindering the oxygen and lithium ion diffusion. Besides, the redox reactions should be reversible for high efficiency and long lifetime of LABs.
Herein, we propose a carbon nanocomposites derived from metal-organic frameworks (MOFs) grown on carbon-nanotubes (CNTs) as a cathode for LABs. The MOF-derived materials provide large pore volume to accommodate the products as well as catalysts for facilitating the electrochemical reactions during the charge and discharge. Meanwhile, CNTs adds more pore and enhance the electrical conductivity of the materials. |
