CARBON COATED ELECTROCHEMICALLY ACTIVE POWDER |
| 摘要 |
T The invention relates to an electrochemically active powder comprising particles containing a compound represented by formula AaMm(XO4)n wherein A comprises an alkaline metal; M comprises at least one transition metal and optionally at least one non- transition metal; and X is chosen among S, P and Si; wherein 0<a≤3.2; 1≤ m≤2; and 1 ≤n≤3; wherein said particles are at least partially coated with a layer comprising a carbonaceous material, said carbonaceous material comprising a highly ordered graphite, wherein said highly ordered graphite has a ratio (Ι1360/Ι1580) of a peak intensity (I1360) at 1360 cm-1 to a peak intensity (hsso) at Ι1580cm-1, obtained by Raman spectrum analysis, of at most 3.05. |
