For practical application of lithium–sulfur batteries (LSBs), designing devices with an overall optimal structure instead modifying electrode materials is significant. Herein, we report a chip-inspired design vertically integrated as LSB cathode by implanting Mo2C nanoparticles and nanosulfur into the reduced graphene oxide (rGO) matrix. This configuration enabled synthesis isolated sulfur nanoreactors (S-NRs) in tandem array on rGO, generating chip-like LSBs. The spatial...
The practical application of lithium–sulfur batteries (LSBs) is hampered by the slow lithium polysulfide (LIPS) conversion kinetics and uncontrollable anode-metal dendrites. Herein, a three-dimensional cation dual-active-site eggshell structure compound (3DCS-FMO@C) was synthesized soft template, ion exchange, pyrolysis to modify commercial separator. Experimental theoretical analysis results showed that Mn2+ Fe2+ sites in 3DCS-FMO@C can synergistically adsorb LIPSs, effectively regulate...
