| Abstract |
A Li_(1.05)CoO₂ powder has been prepared by the solid state reaction of Li₂CO₃ and Co₃O₄ at 1000℃. Li_(1.05)CoO₂ powder was characterized a layered structure with space group of R3￣m by XRD analysis. But Li_(1.05)CoO₂ has a shorter c-axis than LiCoO₂ because, in the former case, a coulombic interaction is more dominent than elastic strain energy effect. In this experiment, electrochemical properties about porous Li_(1.05)CoO₂ were investigated by galvanostatic, CV(Cyclic Voltammetry) and GITT(Galvanostatic Intermittent Transient Technique) method. |
