摘要：
We report the influence of dilution effect on the synthesis and electrochemical profiles of integrated spinel layered 0.5Li(Mn1.5Ni0.5)O-4. 0.5(Li2MnO3 Li(Mn0.5Ni0.5)O-2) cathodes prepared by scalable continuous stirred tank reactor (CSTR). Apparently, the dilution of chelating agent or precursor solutions leads to the formation of unavoidable impurity phases. However, the presence of such impurity traces certainly improves the electrochemical stability of such spinel layered integrated electrodes. In addition, influence of operating potential is also investigated and it was found that 2./1 /1.8 V vs. Li is the optimal condition to yield high capacity and high performance cathode material.
