Fabrication of the Ni-NiCl2 Composite Cathode Material for Fast-Response Thermal Batteries

Fabrication of a novel TiO2/S composite cathode for high performance lithium–sulfur batteries

Sulfur is an attractive cathode material with a high specific capacity of 1675 mA h g , but its rapid capacity decay due to polysulfide dissociation presents a significant technical challenge. Here, we present the fabrication of a TiO2/S composite cathode by encapsulating elemental sulfur into TiO2 nanotube hosts for high performance lithium–sulfur batteries. A high capacity of 913 mA h g 1 has...

Electrochemical characterization of a polypyrrole/Co0.2CrOx composite as a cathode material for lithium ion batteries

Polypyrrole/Co0.2CrOx, (PPy/Co0.2CrOx) composites were synthesized by polymerizing pyrrole onto the surface of cobalt chromium oxide (CrOx) in acidic media. The PPy/Co0.2CrOx composites increase the reversible capacity of the electrochemically active material up to 20%. At C/10 rate, a reversible capacity of 215 mAh/g was obtained for PPy/Co0.2CrOx composite, compared to 178 mAh/g for the virgi...

Composite Cathode Material for Li-Ion Batteries Based on LiFePO4 System

Vanadium Pentoxide-Based Composite Synthesized Using Microwave Water Plasma for Cathode Material in Rechargeable Magnesium Batteries

Multivalent cation rechargeable batteries are expected to perform well as high-capacity storage devices. Rechargeable magnesium batteries have an advantage in terms of resource utilization and safety. Here, we report on sulfur-doped vanadium pentoxide (S-V₂O₅) as a potential material for the cathodes of such a battery; S-V₂O₅ showed a specific capacity of 300 mAh·g-1. S-V₂O₅ was prepared by a m...
