A Highly Hierarchical Hollow Sodium Sulfide Nanospheres Embedded in
Spongy Carbon Composite As Cathode for High-Rate Performance Sodium-Sulfur
Batteries
Substituting electroinactive Al3+ into vanadium ferrite aerogels boosts capacity to battery-relevant levels but in a material that expresses pseudocapacitive character and high-rate performance.
An external force field-assisted electrochemical exfoliation method was adopted to produce few-layered bismuthene nanosheets (FBNs). These FBNs exhibited a high rate performance and ultra-long cycle life for KIBs anode.
