Dependence of the Structures of Manganese Dioxides on Their Chemical Properties

Chemical properties of four manganese dioxides from different sources were investigated by means of a solvothermal method. The reactions of manganese dioxides with lithium chloride were carried out in 1-hexanol at 170°C. All manganese dioxides used in this work consist of two kinds of building blocks, i.e., the 2 x 1 tunnel and the 1 x 1 tunnel. The tunnel structure strongly affects chemical behaviors: manganese dioxide with the 1 x I tunnel results in the formation of the spinel lithium manganese oxide; a novel structural Li x MnO 2 can be made from manganese dioxide with the 2 x 1 tunnel. The concentration of each product is sensitive to the content of the corresponding building block in a precursor. On the other hand, the microtwinning and the surface reaction may also affect the formation of the products. Both products were formed by different paths. Insertion of lithium ions into the 2 x 1 tunnels was observed; however, insertion into the 1 x 1 tunnels was not detected. The difference between them may be explained by the space and the energy of the building blocks.
