| 제목 | Problems of lithiated anode in lithium oxygen batteries |
| 초록 | Lithium oxygen battery is attractive battery system because of high energy density. 1-2 The works about substitution of Li metal which has inherent limitation of stability and long term cycling property. Here in, we demonstrate the unsolved problem of lithium oxygen full cell system using alternative anode (lithiated Si-CNT composite) for lithium metal by XRD and SEM analysis. The returning lithium ion at the charge forms the lithium hydroxide which passivates the anode by side reaction with moisture in electrolyte and from outside. Side reactions, leading to the formation of LIOH at the anode site caused loss of the Li source, resulting in decreased potential and poor cycle of the Li-O2 full-cell system. (1) V. S. Bryantsev, V.
