Long-life and dendrite-free zinc metal anode enabled by a flexible, green and self-assembled zincophilic biomass engineered MXene based interface

The Emergence of 2D MXenes Based Zn‐Ion Batteries: Recent Development and Prospects

“…MXene materials have also demonstrated their unique contributions in designing favorable structures [204] and have been effectively used in aqueous dendrite-free Zn anodes. [205] Feng's group [206] reported a mixed suspension of MXene nanosheets and chitosan-coated on Zn foil by a simple blade-casting method to fabricate MX/CS@ Zn anode (Figure 14a). Notably, the MX/CS@Zn foil still retains its surface integrity even after twisting and folding, indicating the intense contact between MX/CS layers with Zn foils (Figure 14b).…”

“…Initially, flexible Ti 3 C 2 T x -MXene paper was synthesized. After that, Zn particles were electrodeposited in the MXene framework using [206] Copyright 2020, Elsevier. f) Representation of synchronous assembling/ reducing MXene layer on Zn-foil with plating behavior of MXene-coated Zn and pure Zn, g) optical image, h) contact angles of electrolyte, i) SEM image with corresponding EDS images, j) voltage hysteresis, k) cycle performance.…”

Ultrastable and High‐Rate 2D Siloxene Anode Enabled by Covalent Organic Framework Engineering for Advanced Lithium‐Ion Batteries

“…Particularly, nanocrystallization silicon-based anode materials seem to be useful way to surmount above problems. [20,21] A lot of nanostructures have been constructed such as 0D structures (hollow and porous nanoparticles), 1D structures (nanotubes, nanowires), and 2D structures to enhance the electrochemical performance of Si-based anode for LIBs. [22][23][24][25] In regard to the various nanostructures designs, 2D nanostructure due to the special layer structure and minor volume expansion have attracted wide interest.…”

Co3O4 nanoparticle-dotted hierarchical-assembled carbon nanosheet framework catalysts with the formation/decomposition mechanisms of Li2O2 for smart lithium–oxygen batteries

“…Energy shortage and environmental problems have led to a positive search in energy consumption and conservation. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Among multitudinous types of storage and conversion technologies, rechargeable Li-O 2 batteries [21][22][23][24] (LOBs) are regarded as the potential candidates for energy storage owing to their ultra-high theoretical energy density reaching 3600 W h Kg −1 , originating from the process of oxygen being reduced to form lithium peroxide (2Li + O 2 ↔ Li 2 O 2 , 2.96 V vs. Li/Li + ), which is nearly ten times higher than commercialized lithium-ion batteries. [25][26][27] However, in comparison with an ideal reaction process, complex reaction mechanisms and possible by-products exist resulting in challenges [28][29][30] including inferior specific capacity, low round trip energy efficiency, poor cycle performance, which hinder its further development.…”
