Synthesis and electrochemical characteristics of NASICON-structured LiSn2 (PO4) 3 anode material for lithium-ion batteries
Li3PO4, with a Li ion conductivity of 8.62× 10− 8 S cm− 1, is considered as a matrix material
in this study to improve the cyclability of tin anodes. Toward this goal, a well-crystallized
NASICON-structured LiSn2 (PO4) 3 using nano-SnO2 as a precursor has been prepared at
900° C using a solid-state reaction. Compared to SnO2, this material exhibits better cycling
performance, with a capacity of 320 mAh g− 1 after 50 cycles. Additionally, the
insertion/extraction mechanism of LiSn2 (PO4) 3 is investigated through ex-situ X-ray …

Li3PO4, with a Li ion conductivity of 8.62 × 10−8 S cm−1, is considered as a matrix material in this study to improve the cyclability of tin anodes.

Compared to SnO2, this material exhibits better cycling performance, with a capacity of 320 mAh g−1 after 50 cycles. Additionally, the insertion/extraction mechanism of LiSn2(PO4)3 is investigated through ex-situ X-ray diffraction (XRD) and electrochemical impedance spectroscopy (EIS) measurements. The apparent diffusion coefficient (DLi) is studied using cyclic voltammetry (CV) experiments employing a powder microelectrode. In addition, differential scanning calorimetry (DSC) measurements are employed to investigate the thermal stability of LiSn2(PO4)3.
