MoP@C nanocomposite, combined three-dimensional (3D) honeycomb carbon matrix with molybdenum phosphide, was synthesized through a simple hard template method followed by high-temperature phosphating treatment. The MoP@C has shown excellent sodium and potassium-ion storage properties applied as anode materials for sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs). The MoP@C composite maintains a high reversible specific capacity of 250 mAh g−1 in SIBs after 100 cycles at 0.5 A g−1. Furthermore, even at a high current density of 5 A g−1, it still delivers a specific capacity of 200.5 mAh g−1. Additionally, the nanocomposite holds 147.2 mAh g−1 at a high current density of 1 A g−1 in PIBs. The excellent electrochemical performance benefits from the synergistic effect of the hierarchical MoP@C nanostructure. The exquisite porous nano-frame with higher conductivity and larger specific surface area, the active substance is fully infiltrated in the electrolyte, and su
The use of Sodium-ion battery is expected to reduce the cost of the Electric Vehicles by at least 10 per cent, increasing the viability of EVs as compared to petrol, diesel or CNG vehicles.
A sodium-ion battery has been installed in an all-electric car for the first time and Volkswagen is involved. There are many yet-to-be-proven advantages .
Increasing generation of permanent magnet waste has resulted in an urgent need to preserve finite resources. Reforming these wastes as feedstock to produce renewables is an ideal strategy for addressing waste and energy challenges. Herein, our work reports a smart and sustainable strategy to convert iron in magnet wastes into Prussian blue analogues that can serve as cathode materials for sodium-ion batteries. Moreover, a method to control feed rates is proposed to generate high-quality materials with fewer [Fe(CN)6] vacancies at a feed rate of 3 mL min-1. The recycled Na1.46Fe[Fe(CN)6]0.85·□0.15shows low vacancies and excellent cycling stability over 300 cycles (89% capacity retention at 50 mA g-1). In operando, evidence indicates that high-quality Prussian blue allows fast sodium-ion mobility and a high degree of reversibility over the course of cycling, although with a three-phase-transition mechanism. This study opens up a future direction for magnet waste created with the expec
