Sulfur defects engineering enables high-performance manganese sulfide anode

Tailoring the electronic structure of the NaTi2(PO4)3 anode for high-performing sodium-ion batteries via defect engineering

“…However, similar to other NASICON-type materials, the practical applications of NTP are severely plagued by its low intrinsic electronic conductivity, 29 leading to low capacity and poor rate capability. To address these issues, many strategies, such as carbon coating, [30][31][32] morphology control, [33][34][35][36] and nanoscale engineering, [37][38][39][40][41] have been developed to enhance the electronic conductivity and diffusion kinetics. 42,43 Meanwhile, oxygen defect engineering has been widely utilized in oxide-or phosphate-based anode materials to improve both electronic and ionic conductivities, thereby significantly boosting their electrochemical performance.…”
