| Abstract: | Good crystal properties and high purity of β-Co(OH)_2 and CoOOH were prepared in home-made continuous reactor.Well-ordered high-temperature LiCoO_2 is synthesized by high temperature solid state reaction through β-Co(OH)_2 and CoOOH as precursors,respectively reacted with LiOH·H_2O.The structure of β-Co(OH)_2,CoOOH and LiCoO_2 was studied and characterized by XRD,SEM and IR.And the electrochemical properties of LiCoO_2 was studied and compared. |
