Polypyrrole hollow nanospheres: stable cathode materials for sodium-ion batteries.
Hollow polypyrrole (PPy) nanospheres with high sodium storage capacity as cathode materials for Na-ion batteries were reported. PPy hollow nanospheres demonstrated high current rate capacity and good cyclability. It was revealed by electrochemical testing and DFT calculation that the as-prepared PPy hollow nanospheres participate in reversible doping/de-doping reactions.
متن کاملSol-Gel Synthesized Antimony Anodes for Sodium-Ion Batteries: Identifying Key Parameters for Optimization
The potentially high gravimetric capacities of intermetallic anodes, coupled with the low cost and readily available materials used in sodium-ion batteries, has generated interest in antimony—an anode capable of alloying with sodium. However, presently there are few synthetic routes to antimony particles for use in sodium-ion batteries. One pot, sol-gel synthetic routes from readily available, ...
متن کاملHumic acid as promising organic anodes for lithium/sodium ion batteries.
As a representative natural polymer with abundant functionalities, humic acid was creatively explored as an anode material for lithium ion batteries and sodium ion batteries with high storage capacities, and satisfactory cycling stabilities. Most impressively, this work provides a promising and effective strategy for developing organic energy storage devices from natural sources.
متن کاملStable Cycling of SiO2 Nanotubes as High-Performance Anodes for Lithium-Ion Batteries
Herein, SiO2 nanotubes have been fabricated via a facile two step hard-template growth method and evaluated as an anode for Li-ion batteries. SiO2 nanotubes exhibit a highly stable reversible capacity of 1266 mAhg(-1) after 100 cycles with negligible capacity fading. SiO2 NT anodes experience a capacity increase throughout the first 80 cycles through Si phase growth via SiO2 reduction. The holl...
متن کاملHybrid tin oxide nanowires as stable and high capacity anodes for Li-ion batteries.
In this report, we present a simple and generic concept involving metal nanoclusters supported on metal oxide nanowires as stable and high capacity anode materials for Li-ion batteries. Specifically, SnO(2) nanowires covered with Sn nanoclusters exhibited an exceptional capacity of >800 mAhg(-1) over hundred cycles with a low capacity fading of less than 1% per cycle. Post lithiation analyses a...
