Polypyrrole hollow nanospheres: stable cathode materials for sodium-ion batteries.
نویسندگان
چکیده
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.

NiSb alloy hollow nanospheres (HNSs) obtained by galvanic replacement were firstly applied as anode materials for lithium ion batteries, giving the best electrochemical performances for NiSb alloy materials so far with a high reversible capacity of 420 mA h g(-1) after 50 cycles, close to its theoretical capacity (446 mA h g(-1)).
متن کاملSurfactant-Templated Synthesis of Polypyrrole Nanocages as Redox Mediators for Efficient Energy Storage
Preparation of conducting-polymer hollow nanoparticles with different diameters was accomplished by surfactant templating. An anionic surfactant, namely sodium dodecylbenzenesulfonate, formed vesicles to template with the pyrrole monomer. Subsequent chemical oxidative polymerization of the monomer yielded spherical polypyrrole (PPy) nanoparticles with hollow interiors. The diameter of the hollo...
