Abstract

Misfit-layered calcium cobaltites (Ca₃Co₄O₉, Ca₃Co_3.9Fe_0.1O₉, and Ca₃Co_3.9Mn_0.1O₉), as anode materials for lithium-ion batteries, were synthesized by a simple hydro-decomposition method. All synthesized samples do not show any impurity phase. They exhibited plate-like particle with the particle size of 1–2 μm. The specific capacities of doped samples showed higher electrochemical performance compared to the undoped sample. After charge/discharge of 50 cycles, the specific capacities of Ca₃Co₄O₉, Ca₃Co_3.9Fe_0.1O₉, and Ca₃Co_3.9Mn_0.1O₉ were 343, 562, and 581 mAh g⁻¹, respectively. The doped samples showed an increase of over 60% compared to the undoped sample. The cyclic voltammetry profile of the doped samples showed the enhanced reactivity corresponding to their improved electrochemical performance. The capacity improvement of doped samples resulted from the metal oxide/Li conversion reactions, volume change, and high reactivity.
