Lithium-sulfur batteries are presented as a promising alternative for the operation of those devices, including electric vehicles, that require higher specific capacity than current lithium-ion technology. Unfortunately, lithium-sulfur batteries suffer from several limitations that still produce a relatively fast capacity fading and poor utilization of active materials. In order to alleviate the disadvantages that arise at the cathode, several researchers have searched for new electrode materials. Because of the long standing tradition in the use of carbons in energy storage systems, carbonaceous cathodes have been the most popular choice. Recently, however, there has been a trend for the study of non-carbonaceous materials as cathodes in lithium-sulfur systems. Materials such as polymers, metal oxides, metal carbides, amongst many others were reported, showing excellent properties which make them compete side by side with state of the art carbonaceous cathodes. These materials have generally improved the conductivity of the conventional sulfur electrode, and have provided a 3D soft adsorbent porous structure, which efficiently traps polysulfides. These characteristics are reflected in an improved electrochemical performance, reaching, in some cases, capacity retention values close to 1000 mA h g(-1) after 100 cycles at high discharge rate. Here, we propose a review of these non-carbonaceous cathodes. (C) The Author(s) 2018. Published by ECS.
