▎ 摘 要
NOVELTY - Preparing material for positive electrode involves obtaining the solid phase of the first mixture, the first mixture comprises a sodium source and Me source, where the Me is manganese, iron, copper, nickel, zinc, cobalt, magnesium, aluminum, chromium, titanium, lithium, zirconium, lanthanum, tellurium, strontium, calcium, boron, vanadium, yttrium, tin, molybdenum, silicon, ruthenium, niobium, antimony, tungsten, cerium; mixing the first mixture with a solvent to obtain a second mixture; carrying out solid phase; sintering to the second mixture to obtain the material positive electrode. USE - Method for preparing material for positive electrode used in sodium-ion battery. ADVANTAGE - The method is capable of preparing the positive electrode material with high tap density, high vibration density, compact surface, small surface, and low cost, and synthesizing suitable for sodium ion battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a sodium ion battery where positive electrode material.
