Complex metal oxides like La0.5Sr0.5CoO3-δ(LSCO) possess important applications in the field of electrochemical energy storage and transformation, for example, rechargeable metal-air battery, electrochemical water splitting, Li ion battery and so forth. However, their preparation is still a challenge, especially for precisely controlling their stoichiometry. In this proposal, we will further study the aerosol spray assissted approach for accessing mesoporous complex metal oxides electrode materials and their properties modification based on our previous findings. We propose to develop this approached as a ripe and versatile methodology to prepare, modify and produce complex metal oxides for electrochemical energy devices. Meanwhile, we will do some fundametal study on the correlation of composition-electrostructure-property of complex metal oxides by the proposed approach due to its facile and accurate control of composition stoichiometry. Lastly, we will made corresponding electrochemical devices using the obtained complex metal oxides, evaluate their performace and idetify the excellent materials. Therefore, this proposal is very important in both of the theoretical research and pratical applications.
