Three dimensional Ti₃C₂ MXene nanoribbon frameworks with uniform potassiophilic sites for the dendrite-free potassium metal anodes

Abstract

Potassium (K) metal batteries hold great promise as an advanced electrochemical energy storage system because of their high theoretical capacity and low cost. However, the practical application of K metal...

Electrical Conductivity Enhancement and Electronic Applications of 2D Ti3C2Tx MXene Materials

“…Although Ti 3 C 2 T x with good conductivity in some electronic devices is widely studied in research, such as supercapacitors, [ 22 ] metal ion batteries, [ 104 ] sensors, [ 25 ] and so on. Nevertheless, only a small amount of work reports the application of Ti 3 C 2 T x MXene on vacuum electronic devices or semiconductor electronic devices such as field emission devices, [ 14c,27 ] transistors, [ 107a ] triboelectric nanogenerators (TENG), [ 90,109 ] and so on, all of which still requires lots of research efforts to implement them.…”

“…Applications mentioned previously are only a small portion of all practices of Ti 3 C 2 T x MXene in electronics. It also has remarkable performance in supercapacitors, [ 22 ] metal ion batteries, [ 104 ] conductive films, [ 13,15 ] plasma equipment, [ 105 ] photoelectric detectors, [ 106 ] transparent conductors, [ 23 ] and thermoelectric materials. [ 26 ] For instance, solution processed Ti 3 C 2 T x films as transparent conductors exhibited a low sheet resistance of 437 Ω·sq −1 and a transmittance of 77% at 550 nm.…”

Homogeneous Na Deposition Enabling High‐Energy Na‐Metal Batteries

“…[ 15 ] Typically, the MXenes as an emerging 2D multifunctional material with an oxygen‐rich surface has been generally used in metal anodes. [ 108–110 ] Moreover, a recent study reported that parallelly aligned MXene layers enable the induced horizontal Li growth behaviors. [ 65 ] Based on these achievements, recently, Cao and co‐workers proposed a stable and flexible composite host (MXene‐coated carbon cloth, Ti 3 C 2 T x ‐CC) for SMA.…”

Balsa‐Wood‐Derived Binder–Free Freestanding Carbon Foam as High‐Performance Potassium Anode

“…A potassium‐ion battery (PIB) is a promising technology in energy storage systems with the advantages of abundant reserves, similar working mechanism to lithium ion batteries and competitive cost. [ 1–14 ] Carbon materials are the cornerstone of the commercialization of PIBs, which attracted lots of attention. A wide variety of carbon materials, such as hard carbon, [ 5,15–18 ] soft carbon, [ 5,19–21 ] carbon nanofibers, [ 22 ] and reduced graphene oxide, [ 23 ] have been investigated as the promising anodes for PIBs in terms of the superior thermal stability, [ 24 ] extensive resource, [ 25 ] and excellent potassium storage capacity.…”
