Prussian Blue Mg—Li Hybrid Batteries
The major advantage of Mg batteries relies on their promise of employing an Mg metal negative electrode, which offers much higher energy density compared to graphitic carbon. However, the strong coulombic interaction of Mg2+ ions with anions leads to their sluggish diffusion in the solid state, which along with a high desolvation energy, hinders the development of positive electrode materials. ...
متن کاملStructure optimization of Prussian blue analogue cathode materials for advanced sodium ion batteries.
A structure optimized Prussian blue analogue Na1.76Ni0.12Mn0.88[Fe(CN)6]0.98 (PBMN) is synthesized and investigated. Coexistence of inactive Ni(2+) (Fe-C≡N-Ni group) with active Mn(2+/3+) (Fe-C≡N-Mn group) balances the structural disturbances caused by the redox reactions. This cathode material exhibits particularly excellent cycle life with high capacity (118.2 mA h g(-1)).

room temperature and then maintained at 80°C for 3 h to form micro-cubic PB particles. The solid product was collected by centrifugation and washed six times with Milli-Q water. The final PB product was then dried in a vacuum oven. The GO was synthesised by a modified Hummer's method. [1] To prepare GOPCs, the GO and PB were stirred together in an aqueous solution to form slurries with differen...
متن کاملSodium Manganese Oxide Thin Films as Cathodes for Na-Ion Batteries
This paper presents the fabrication and characterization of sodium manganese oxide cathode thin films for rechargeable Na-ion batteries. Layered oxide compounds of nominal compositions Na0.6MnO2 and Na1.0MnO2 have been prepared by radio frequency magnetron sputtering and post-annealing at high temperatures under various conditions. The Na0.6MnO2 thin films possess either a hexagonal or orthorho...
متن کاملLi2MnSiO4 Nanostructured Cathodes for Rechargeable Lithium-Ion Batteries
Rechargeable lithium-ion battery technology dominates the portable electronics market following the rapid growth in demand since the introduction of the first, commercial lithium-ion battery by Sony in 1990 [1]. Motivated by concerns for global warming and environmental degradation, researchers have focused on extending the use of rechargeable lithium-ion batteries to large-scale applications. ...
