The monophasic LiCoO2 powders with a layered structure are completely formed after calcining the precursors at 800¢XC. The cationic concentration of the aqueous phase determines the crystallinity and particle size of the obtained powders. Raising the cationic concentration improves the crystallinity and also increases the particle size of LiCoO2 powders. LiCoO2 powders prepared from the high cationic concentration exhibit high discharge capacity, high coulomb efficiency as well as good cyclability.CathodeEmulsion SynthesisLithium Cobalt OxideLithium-Ion BatteryPowders[SDGs]SDG7Calcination; Cathodes; Crystals; Electric discharges; Lithium batteries; Particle size analysis; Positive ions; Powders; Secondary batteries; Synthesis (chemical); Layered structures; Lithium compoundsconference paper2-s2.0-0036027792https://www.scopus.com/inward/record.uri?eid=2-s2.0-0036027792&partnerID=40&md5=7b4fc9d44308963d0246b64884fefc98
