Enhanced Electrochemical Performance

A facile approach is developed to fabricate polypyrrole-encapsulated lamellar iron (II) selenide (FeSe/PPy) by directly exposing FeSe to pyrrole atmosphere at room temperature. A high FeSe loading of 97 wt.% is achieved for the FeSe/PPy composite, which is designed as an anode for lithium-ion battery (LIB) with much enhanced electrochemical performance than that of the FeSe sample. The FeSe/PPy electrodes demonstrate a reversible discharge capacity of 274 mAh g[Formula: see text] after 50 cycles at a high current density of 0.5 A g[Formula: see text], whereas the lower discharge capacity of 124 mAh g[Formula: see text] for the FeSe electrodes. The FeSe/PPy electrodes also deliver greater rate capability compared to the FeSe electrodes. The improved electrochemical performance should be assigned to the contributions of fast charge transfer and structural defense from the encapsulated PPy. Hence, the FeSe/PPy composite could serve the purpose for constructing reliable anode for LIB, and the simple method of PPy coating can also be used to build high-performance electrodes for other battery systems.

Abstract Bare PbS QDs and PbS-GQDs nanocomposite were prepared by chemical methods for supercapattery application and characterized by suitable analytical techniques confirming the formation of PbS-GQDs nanocomposite. The electrochemical performance of the fabricated electrodes showed that the PbS-GQDs nanocomposite exhibited high specific capacity, energy and power densities of 577.94 C g-1 , 166.45 Wh kg-1 and 576.01 W kg-1 respectively at 2 A g-1 compared to that of bare PbS QDs. The enhanced electrochemical performance of PbS-GQDs can be associated with the conductive platform provided by synergistic effect of GQDs. The nonlinearity in charge and discharge curves confirms the supercapattery behaviour of the nanocomposite. Also, PbS-G QDs nanocomposite electrode showed highly cyclic stability compared to bare PbS QDs after 5000 cycles. The results emphasize the potential of PbS-G QDs nanocomposite as a stable active electrode material for energy storage application.

Shuttle-like CuO has been synthesized by treating commercial Cu(OH)2 powder at room temperature for an appropriate time. As anode material of lithium-ion batteries, shuttle-like CuO exhibits high specific capacity, high stability, and good rate performance, superior to commercial CuO powder. The shuttle-like CuO exhibited a high specific capacitance of 456.8 mAh g-1 at a current density of 100 mAg-1 and maintained a good stability in 50 cycles, suggesting that it can be a promising candidate for lithium-ion batteries. The high specific capacitance and remarkable rate capability are promising for applications in lithium-ion batteries with both high energy and power densities.
