Research Progress on Structure and Doping of Lithium Manganese Oxide Ion-sieve

As a type of absorbents which can be used for selective-adsorption of lithium,Spinel Lithium manganese oxide has brought future,but the big obstacle that prevented it forms being commercialized is its high dissolution ratio.The structure of spinel lithium manganese oxide ion-sieve is introduced,dissolution of Mn and Jahn-Teller effect are found in the main causes of its dissolution.The method of restraining dissolution of Mn and Jahn-Teller effect by doping modification is mainly discussed about,thus the structure of spinel becomes steadier.
