Abstract：The devolvement of preparation methods and applications of layered manganese dioxide at home and abroad were reviewed. The preparation methods of layered manganese dioxide， such as solid reaction method， hydrothermal method， sol-gel method and liquid oxidationreduction method， et al were summarized. The applications of layered manganese dioxide in lithium battery electrode materials， cation exchange materials， adsorption materials and elimination pollutions materials were described. The progress in preparation and applications of layered manganese dioxide were prospected. The results showed that their development in the future was forecasted. The solid reaction method was used widely in the practical production and research， and the liquid phase methods had many merits such as nontoxicity， low cost, high energy density， which was worthy of strongly development and expansion. The improving technologies would provide a good prospects for layered manganese dioxide.
