Porous Carbon Spheres: Rational Design of Si/SiO2 @Hierarchical Porous Carbon Spheres as Efficient Polysulfide Reservoirs for High-Performance Li-S Battery (Adv. Mater. 16/2016).
S. Guo, Y. Hou, and S. Rehman develop a new class of silicon crosslinked with hierarchical porous carbon spheres usable as an efficient polysulfide reservoir for enhancing the performance of lithium-sulfur batteries. As described on page 3167, the developed hybrid material adsorbs negatively charged polysulfides via both chemical and physical adsorption. Remarkably, the hybrid spheres show a high specific capacity, an excellent rate capability and long cyclability.
