Building Na-ion full cells using homologous Prussian blue and its phosphide derivative

Graphene cladded cobalt phosphide nanoparticles with a sandwich structure by plasma for lithium and sodium storage

“…P-C bonds (132.5 eV) occur, suggesting that part of the P atoms are implanted into the carbon lattice. 17,27,28 The intrinsic interaction constructs a heterojunction interface between the dispersed CoP nanospheres and RGO layers.…”

Resolving Deactivation of Low-Spin Fe Sites by Redistributing Electron Density toward High-Energy Sodium Storage

“…Lithium-ion batteries (LIBs) have become the ubiquitous power supplier in energy storage fields. − However, low abundance and the geopolitical issues surrounding lithium resources present the main risks for further development. − As an emerging alternative, sodium-ion batteries (SIBs) have garnered enormous research activities as a promising beyond-lithium technology due to the wide reserve of sodium resources. , However, the foremost challenge in advancing SIBs lies in exploiting promising cathode materials with outstanding electrochemical performance. − Among the available cathode materials, Prussian blue (PB) has been deemed as one of the most fascinating cathode candidates due to its high theoretical specific capacity up to 170 mAh g –1 and the natural abundance of Fe element. − However, its development has been substantially hindered by its unsatisfactory specific capacity in practical application.…”
