제목 Synthesis of the layered-spinel composite for Li-ion battery by using flame spray pyrolysis
초록 The research effort of Li-ion batteries has been conducted for high-power application such as HEV. However, Li-ion batteries currently do not meet requirements. Despite the high capacity of layered-layered composite electrodes, they have drawbacks such as inferior rate capability and cycle performance.Recently, some groups proposed the layered-spinel electrodes to design high capacity and high rate capability. These electrodes compensate the low rate capacity of the layered electrode by integrating spinel phase, because it has a good rate capability, even if it has low capacity values. The electrochemical performance of Li-ion batteries is depends on the crystallinity, phase purity, particle morphology and surface area which depend on synthesis method. Flame spray pyrolysis (FSP) is a suitable process to synthesize electrode material, because the particles prepared by FSP exhibit high purity, controlled size, and clear crystallinity.
In this work, the integrated layered-spinel composite was synthesized by using flame spray pyrolysis. The characteristic of material according to the ratiooflayered to spinelanalyzed by XRD. Following the characterization, the electrochemical performance test was conducted.
