C/Li2MnSiO4 Nanocomposite Cathode Material for Li-Ion Batteries

Amorphous Sb2S3 embedded in graphite: a high-rate, long-life anode material for sodium-ion batteries.

Amorphous Sb2S3 embedded in a conductive graphite matrix is designed for sodium-ion batteries. Owing to the amorphous structure of the active phase and the conductive graphite matrix, the Sb2S3-graphite electrode exhibits a high initial Coulomblic efficiency, a high rate capacity, and stable cycle performance in sodium-ion batteries.

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.

Na2CoSiO4 as a cathode material for sodium-ion batteries: structure, electrochemistry and diffusion pathways.

The importance of developing new low-cost and safe cathodes for large-scale sodium batteries has led to recent interest in silicate compounds. A novel cobalt orthosilicate, Na2CoSiO4, shows promise as a high voltage (3.3 V vs. Na/Na+) cathode material for sodium-ion batteries. Here, the synthesis and room temperature electrochemical performance of Na2CoSiO4 have been investigated with the compo...
