Heterogeneous-based functionalized nanocomposite materials have attracted considerable attention in both energy storage and conversion processes due to their fast electron transfer process and their long life cycles. Herein, we discuss different kinds of techniques, which are used for the fabrication of carbon-based nanocomposites like sol-gel, hydrothermal (HT), in-situ polymerization and electrochemical methods, etc. In particularly, functionalized carbon decorated nanocomposites have been focused on the designing and development of rational candidate for future energy technologies. In particular, the highlighted nanocomposites have attracted more attention in the energy technology area because of their larger electrode surface area, high mechanical strength, excellent electrochemical properties, and rapid electrochemical redox behaviour. Considerable advancements in the combinations of nanoscale-based composite devices offer potential for the development of new energy storage technology to fulfill the global energy demands. Finally, we summarize the recent advantages of carbon supported composite, which significantly enhanced their electrochemical energy storage properties like high capacitance and boosted specific capacitive values.

“…8,20 Noncovalent modications involve physical adsorption of biorecognition elements onto the CNT surface through p-p, hydrophobic, or electrostatic interactions. 21,22 The traditional noncovalent functionalization of CNTs is through the usage of 1-pyrenebutyric acid N-hydroxysuccinimide ester (PBASE) as a linker molecule. Here, the benzene rings of PBASE attach to the CNTs due to p-p stacking interactions, while the ester remains free to react with the primary amines of biorecognition elements.…”

“…For example, Li et al coated a carbon (C) layer on the surface of Si nanoparticles to resist their volume expansion, but the rigid C shell is easily damaged by the stress accumulated from the volume expansion during lithiation. To ensure conductivity while improving the flexibility of the buffer layer, research has focused on developing some flexible conductive substrates, such as graphene − and carbon nanotubes. − However, the preparation process of graphene and carbon nanotubes often requires harsh conditions or involves complex synthesis processes that add extra cost to the product. − Comparatively, MXene, as a novel transition metal carbide or nitride, combines the properties of graphene and graphene oxide with good electrical conductivity, surface chemistry, hydrophilicity, and excellent mechanical properties, which can be used as a good conductive substrate material. − Moreover, its preparation method by etching in LiF-dissolved HCl solution is simple and mild, and it is suitable for large-scale production and application. The general structural formula of MXene is M n +1 X n T x ( n = 1, 2 or 3), in which M represents the former transition metal element, X represents the carbon or/and nitrogen, and T x represents the surface functional group associated with the M layer, such as −F, −O, −OH, etc. , Among them, Ti 3 C 2 T x is the most representative of the MXenes family and has been applied as a conductive buffer substrate for silicon-based anodes.…”

Compared with nanosilicon, microsilicon with high capacity is the best candidate for high-energy-density lithium-ion batteries due to its lower cost and fewer interfacial side reactions. However, particle cracking and even pulverization caused by the huge volume expansion and low ionic conductivity of microsilicon seriously hinder its large-scale application. Here, we prepared a rigid-flexible coupled modification layer for microsilicon flakes (Si) by using polydopamine (PDA) as a bridging agent and MXene (Ti 3 C 2 T x ) as a buffer layer. The hydrogen bonds between groups on PDA and the terminal groups (−OH, etc.) on Si and MXene surfaces can induce the uniform distribution of Si particles on the surface of the MXene, which inhibits the agglomeration of Si particles and the self-accumulation of MXene nanosheets. In addition, the rigid N-doped carbon (NC) layer derived from the high-temperature cracking of PDA coated on the Si surface and the flexible MXene buffer layer synergistically form a hierarchical multiplex conductive network, which not only accelerates the kinetics of the electrode during cycling and suppresses particle cracking but also effectively protects the electrode from the destruction of the decomposition byproducts. As a result, this NC-coated Si uniformly supported on MXene (Si@NC/MXene-2) delivers highly reversible specific capacities of 1066.1 mAh g −1 after 250 cycles at 0.5 A g −1 and 810.9 mAh g −1 after 650 cycles even at a higher current density of 1 A g −1 . This work provides valuable insights for the development of advanced silicon-based anode materials for application in high-energy-density lithium-ion batteries.
