Establishing a durable interfacial layer between an electrode and electrolyte to enable micron-sized silicon-based lithium-ion battery (LIB) anodes achieve superior electrochemical performance is highly desired. Recent studies have shown that heterogeneous encapsulation with enhanced ion/electron transport effective strategy. However, the structural design of existing hetero-coated interface lacks reasonable channel, resulting in high impedance. Herein, we designed heterogenous MXene-mesoporous polypyrrole (mPPy) onto SiO particles. The MXene coating functions as bridging can build strong chemical link internal via covalent bonding, thus reinforcing charge transfer rate. Meanwhile, it forms dynamic connection outer mPPy through hydrogen which contributes Li+ concentration coupling Accordingly, as-prepared SiO@MXene@mPPy anode delivers boosted specific capacity 673.9 mA h g-1 at 2 A after 1000 cycles high-rate capability 777.4 5 g-1. Further, kinetic analysis indicates MXene@mPPy shows pseudocapacitance controlled Li storage mechanism, thereby displaying improved capability. This porous hybrid strategy offers new possibilities for excellent performance.

Two-dimensional layered transition metal dichalcogenides (2D TMDs) have emerged as promising candidates for supercapacitor (SCs) owing to their tunable electronic properties, structures, and effective ion intercalation capabilities. Despite these advantages, challenges such low electrical conductivity, the interlayer restacking, oxidation structural collapse hinder practical implementation. This review provides a comprehensive overview of recent advances in development 2D TMDs SCs. We begin by outlining charge storage mechanisms design principles SCs, followed an in-depth discussion synthesis methods associated fabricating TMD architectures. The subsequent sections explore crystal structures reaction mechanisms, illustrating electrochemical potential Furthermore, we highlight material modification strategies, including nanostructuring, defect engineering, phase control, surface/interface modulation, which been proposed overcome existing challenges. Finally, address critical issues emerging opportunities inspire SC technologies.

In this study, we have investigated the electrochemical performances of a flexible symmetric supercapacitor (FSS) device based on WSe2 nanoflakes thin film electrodes. The electrodes were fabricated using environmentally friendly and cost-effective DC magnetron sputtering. as-prepared FSS was tested in four different aqueous electrolytes containing group 1 alkali metal cations (HCl, LiCl, NaCl, KCl), several techniques, including cyclic voltammetry, galvanostatic charge/discharge, impedance spectroscopy. obtained results revealed that devices with nanoflake-type morphology various exhibit distinctive double-layer characteristics. HCl electrolyte demonstrated highest performance, an impressive areal capacitance 88 mF cm–2 corresponding energy power density 27.5 μWh 3000 μW cm–2, respectively, at constant current 4 mA along solution resistance 0.5 Ω, within operating voltage range 1.5 V. cationic mobility (Li+ < Na+ K+ H+) affects ionic conductivity, efficient ion/charge transition, as well relaxation time is found to be directly correlated value. On other hand, order long-term cycle stability (LiCl NaCl KCl) caused by intricate interactions between ion size, charge density, mechanical stresses, chemical electrode material during charging discharging cycles. Furthermore, use M yields superior performance (88 cm–2) high cycling (75.36% retention after 5000 cycles) cm–2. As result, exert significant impact FSS.
