| Abstract | Abstract: Using a hydrothermal-electrochemical synthesis route, a number of MnO2 materials with α-, β-, or γ- structures have been synthesized. The γ-MnO2 materials obtained are characterized by lower amounts of pyrolusite intergrowth and lower amounts of microtwinning defects compared to those found in γ-MnO2 samples prepared by traditional electrochemical methods. Small amounts of lithium can be incorporated or not into the structure of α-MnO2 materials during the one-step synthesis. The effect of variations in the synthesis conditions on the type of structure obtained and also on the defect rates of the γ-MnO2 structures are presented. The lithium insertion properties of these materials are discussed in relation to their composition and structure. |
