Electrochemical Properties and Synthesis of $LiCoO_2$ Using Lithium Acetate Dihydrate and Cobalt(II) Acetate Tetrahydrate

Lithium Acetate Dihydrate와 Cobalt(II) Acetate Tetrahydrate로 합성한 $LiCoO_2$의 전기화학적 특성

$LiCoO_2$ powder was synthesized by Sol-Gel method using inorganic materials. The starting materials, $CH_3COOLi^*2H_2O\;and\;Co(CH_3COO)_2{^*}4H_2O$, were mixed in the atomic ratio Li/Co of 1 and dissolved in i-propanol with acetic acid. The solution was dried for gelation, and finally obtained the pre-powder. The pre-powder were studied by thermal analysis. Based on the TGA result, heat treatment was performed at various temperature(500 to $800^{\circ}C$) for 2h in air atmosphere. The crystal structure, morphology, electrochemical property were carried out using XRD, SEM, cyclic voltammetry(CV).
