Rechargeable Li–CO2 batteries with carbon nanotubes as air cathodes

Abstract

Rechargeable Li–CO₂ batteries offer great promise by combining carbon capture and energy technology. However, the discharge product Li₂CO₃ is difficult to decompose upon recharging. In this work, carbon nanotubes (CNTs) with high electrical conductivity and porous three-dimensional networks were firstly explored as air cathodes for rechargeable Li–CO₂ batteries.
