Integrated design of Si/SiO2@hierarchical porous carbon spheres is made and used as efficient polysulfide reservoir for enhancing lithium–sulfur battery (LSB) in terms of capacity, rate ability, and cycling stability via combined chemical and physical effects.
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...
