In article number 1702524, Haihui Wang, Shi‐Zhang Qiao, and co‐workers report a novel 3D hybrid sulfur host of nickel sulfide (NiS) and carbon hollow spheres for lithium‐sulfur batteries. The novel sulfur host, produced by a new synthetic method, possesses a unique hollow structure with nanosized NiS uniformly distributed on the carbon spheres, contributing to its high performance.
Lithium–sulfur batteries are a promising next‐generation energy storage device owing to their high theoretical capacity and the low cost and abundance of sulfur. However, the low conductivity and loss of active sulfur material during operation greatly limit the rating capabilities and cycling stability of lithium–sulfur batteries. In this work, a unique sulfur host hybrid material comprising nanosized...
