On rechargeability and reaction kinetics of sodiumair batteries

Rechargeable metalair batteries are widely considered as the next generation high energy density electrochemical storage devices. The performance and rechargeability of these metalair cells are highly dependent on the positive electrode material, where oxygen reduction and evolution reactions take p... Full description

description: Rechargeable metalair batteries are widely considered as the next generation high energy density electrochemical storage devices. The performance and rechargeability of these metalair cells are highly dependent on the positive electrode material, where oxygen reduction and evolution reactions take place. Here, for the first time, we provide a detailed account of the kinetics and rechargeability of sodiumair batteries through a series of carefully designed tests on a treated commercial carbon material. Surface area and porous structure of the positive electrode material were controlled in order to gain detailed information about the reaction kinetics of sodiumair batteries. The results indicate that discharge capacity is linearly correlated with surface area while morphology of the solid discharge product is strongly dependent on specific surface area and pore size. Furthermore, it was found that the chemical composition of discharge products as well as charging overpotential is affected by discharge reaction rate.
