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.

The construction of multicomponent coupled interfaces is crucial to designing highly effective and robust bifunctional electrocatalysts for water splitting. Transition metal sulfides are widely applied as efficient catalysts, but building strong coupling enhance electrocatalytic properties remains a tremendous challenge. Here, we reported distinctive heterostructure electrocatalyst consisting conductive polypyrrole (PPy)-decorated cobalt–molybdenum sulfide (CoS2/MoS2) nanosheets supported on nickel foam (CoS2/MoS2@PPy/NF) using simple two-step hydrothermal subsequent electrodeposition approach. Experimental results reveal that the interfacial synergistic effect between PPy CoS2/MoS2 with tunable electronic configuration favorable charge transport structure optimization interface, where this integrated can improve conductivity offer guarantee durability CoS2/MoS2@PPy/NF. Density functional theory (DFT) calculations verify interaction redistribution in heterogeneous flexibly adjust lower d-band center. Thanks advantages mentioned above, obtained CoS2/MoS2@PPy/NF exhibits outstanding catalytic overpotentials 46 mV hydrogen evolution reaction (HER) 231 oxygen (OER) at 10 mA cm–2. Remarkably, assembled || only acquires 1.52 V cm–2 1.0 M KOH 50 h. This study affords significant reference bimetallic sulfide/polymer catalysts toward high-efficiency overall
