Ultrasmall MoC nanoparticles embedded in 3D frameworks of nitrogen-doped porous carbon as anode materials for efficient lithium storage with pseudocapacitance

Abstract

Ultrasmall MoC nanoparticles anchored in 3D networks of N-doped porous carbon are produced and deliver outstanding lithium storage performance.

How to measure and report the capacity of electrochemical double layers, supercapacitors, and their electrode materials

“…For nanoparticle TiO 2 depending on particle size, more than 50% of the charge storage was deemed to be capacitive, and because it was assigned to surface-near electrode reactions, it was called pseudocapacitive. This pseudocapacitive fraction grew to 84% in case of nano-particular MoC embedded in a 3D network of nitrogen-doped carbon [65]. Unfortunately the displayed results of the impedance measurements are highly selective and incomplete; details on, e.g., the value of C diff might have helped in understanding the reasons of the remarkable power retention.…”

High‐Lithium‐Affinity Chemically Exfoliated 2D Covalent Organic Frameworks

“…Therefore, it is very urgent to develop efficient energy storage materials with excellent electrochemical performance, low price, environmental friendliness, and sustainability . In recent decades, carbon materials, silicon‐based materials, transition metal compounds (oxides, sulfides, selenides, phosphides, and carbides) and organic conjugated polymers have exhibited good performances as electrode materials for Li‐ion batteries (LIBs). In particular, organic materials with low toxicity, resource sustainability, and structural diversity are good candidates for the next‐generation high‐performance batteries .…”

Tuning Interface Bridging Between MoSe2 and Three-Dimensional Carbon Framework by Incorporation of MoC Intermediate to Boost Lithium Storage Capability

“…Introducing intermediate material to bridge the active material and the substrate presents to be a wise choice. Comparing to MoSe 2 , MoC owns intrinsic higher electrical conductivity and chemical stability [30][31][32]. The structural stability and charge transportation will be greatly improved by the incorporation of MoC into the composite, which bridges MoSe 2 and carbon substrates by MoSe 2 -MoC-carbon connection.…”
