Na3V2 (PO4)3 (NVP) is considered to be a promising cathode material for sodium-ion batteries (SIBs). Ion doping can effectively improve its structural deformation, poor conductivity, and electrochemical performance. However, the research on effect of ion thermal stability NVP still limited. In this paper, Mg/Ti co-doped Mn/Ti modified with carbon nanotubes (CNTs) (MgTi@ CNTs MnTi@CNTs) were prepared, respectively, X-ray diffraction (XRD) results proved that MgTi@CNTs MnTi@CNTs have good crystallinity. The performance indicates dual strategy p-n-type co-doping CNT coating provides superior sodium storage performance, enhancing both electronic conductivity diffusion. Secondly, based safety point view, ion-doped mixed system electrolyte in charged state was studied by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), accelerated calorimeter (ARC). show optimized electrodes exhibit excellent absence electrolytes, indicating their high intrinsic safety. it worth noting electrode/electrolyte system, higher reactivity electrolyte, comprehensive lower than NVP. Therefore, practical applications, necessary comprehensively consider electrolyte. This paper data basis application SIBs.
