Improved sodium storage properties NaFePO4/C as cathode material for sodium-ion batteries
Because of the plentiful supply of sodium, sodium ion batteries (SIBs) as one of the most promising technologies for affordable rechargeable batteries. Here, we outline an easy method for creating a NaFePO4@C hybrid composite cathode for SIBs. GCD, CV, and EIS tests have been conducted to study the samples’ electrochemical and kinematic properties. It is confirmed that modest carbon doping can enhance the electrocatalytic activity of NaFePO4 (NFP). The resulting NFP@C nanocomposite as cathode material for SIBs displays good rate capability and lofty capacity (158.5 mAhg−1) retention after 50 cycles at 0.1C. The NaFePO4 and the carbon covering, which make it easier for the Na + ion and electron to access the material quickly during the process of charging and discharging, respectively, are responsible for the good electrochemical performances. This work highlights the value of investigating novel structures and offers a technique for the creation of NaFePO4@C-based cathodes.
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
