“…[10][11][12][13] There are also reports on P and B/S co-doped carbon anodes. [14,15] On the contrary, F doping in carbon introduces a heteroatom which has higher electronegativity relative to C. It increases the interlayer spacing in carbon apart from generating defect sites which improves Li + /Na + mobility and storage capacity in the anode.

Carbon from inexpensive biomass-based precursors have shown promise as anode materials for application in sodium/lithium ion battery technology. However, their practical implementation is marred by unreliable cycling stability and unimpressive initial coulombic efficiency. The electrochemical properties of such biomass derived carbon can be improved considerably by material engineering via suitable heteroatom doping. In this work, the effect of phosphorous and fluorine doping on naseberry seed derived carbon has been explored. The doping led to an increase in the specific capacity and rate performance of the modified bio-based carbon in comparison to non-doped counterparts.The P/F incorporated carbon delivers reversible capacity of 812 mAh g À 1 and 409 mAh g À 1 at 0.1 A g À 1 when tested as anode in lithium/sodium ion coin cell. The long term cycling of the material at a higher current rate of 1.0 A g À 1 is also impressive. The reason for this enhanced electrochemical performance has been analysed through electrochemical impedance spectroscopy and post mortem electron microscopic studies. The increase in interlayer spacing, cell volume and ionic conductivity in the P/F incorporated carbon which leads to an improvement in the electrochemical properties has also been corroborated via DFT analysis.

Sodium‐ion batteries (SIBs) have attracted a significant amount of interest in the past decade as a credible alternative to the lithium‐ion batteries (LIBs) widely used today. The abundance of sodium, along with the potential utilization of electrode materials without critical elements in their composition, led to the intensification of research on SIBs. Hard carbon (HC), is identified as the most suitable negative electrode for SIBs. It can be obtained by pyrolysis of eco‐friendly and renewable precursors, such as biomasses, biopolymers or synthetic polymers. Distinct HC properties can be obtained by tuning the precursors and the synthesis conditions, with a direct impact on the performance of SIBs. In this work, an in‐depth overview of how the synthesis parameters of HC affect their properties (porosity, structure, morphology, surface chemistry, and defects) is provided. Several synthesis‐property relationships are established based on a database created using extensive literature data. Moreover, HC properties are correlated with the electrochemical performance (initial Coulombic efficiency (iCE) and reversible capacity) vs. Na, in half‐cells. The Na‐ion storage mechanisms and solid electrolyte interphase (SEI) formation are discussed along with the HC performance in full‐cell devices, as well as the SIB prototypes and a short history of SIBs enterprises.
