Nitrogen- and oxygen-containing micro–mesoporous carbon microspheres derived from m-aminophenol formaldehyde resin were prepared by the hydrothermal synthesis/carbonization/activation route for high-rate performance supercapacitor application.
A Ni–Co–Se/CNT composite exhibits outstanding Li-ion storage performance with respect to high reversible Li-storage capacity, high cyclability and high rate performance.
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.
