Abstract Since 2020, some new breakthroughs in the field of MXene synthesis scheme such as water‐free etching, HCl‐based hydrothermal halogen and other novel methods have been proposed. Not only that, application zinc‐ion storage devices has also made great progress past 2 years. The understanding mechanism undergone profound changes, its applications become diversified, demonstrating potential for high performance devices. In this review, we summarized preparation materials systematically...
Electrochemical conversion reactions of metal oxides provide a new avenue to build high capacity anodes for sodium-ion batteries. However, the poor rate performance and cyclability these remain significant challenge Na-ion battery applications because most suffer from sluggish kinetics irreversible structural change during cycles. In this paper, we report an Fe2O3 single crystallites/reduced graphene oxide composite (Fe2O3/rGO), where crystallites with particle size ∼300 nm were uniformly...
Rechargeable Zn–air battery is a promising alternative to the widely used lithium–ion battery. Its practical use, however, hindered by low power density, unsatisfactory energy efficiency, poor durability, and unstable voltage output. Here, we demonstrate bifunctional catalyst for oxygen evolution reduction reactions based on 3D MXene coupled with nitrogen-doped cobalt selenide nanocrystals (N-CoSe2/3D Ti3C2Tx). Combining experimental characterizations density functional theory (DFT),...

High-entropy phosphides are first synthesized, achieving much faster charge transfer and greater anti-pulverization capability than the parent phases owing to high configurational entropy.
Although LiNi0.8Co0.1Mn0.1O2 is attracting increasing attention on account of its high specific capacity, the moderate cycle lifetime still hinders large-scale commercialization applications.

Typical layered transition-metal chalcogenide materials, especially MoS2, are gradually attracting widespread attention as aqueous Zn-ion battery (AZIB) cathode materials by virtue of their two-dimensional structure, tunable band gap, and abundant edges. The metastable phase 1T-MoS2 exhibits better electrical conductivity, electrochemical activity, zinc storage capacity compared to the thermodynamically stable 2H-MoS2. However, is still limited stability structure destruction for AZIB...
