摘要： Methods of manufacturing cathode active materials, including preparing a solution of a hygroscopic species and a reactive oxygen species, heating the solution at a temperature that is less than about 400° C. for a time sufficient for a precipitate of the cathode active material to form, and collecting the cathode active material. The cathode active materials can be used to prepare cathodes that evolve little or no oxygen during operation. The cathodes can be economically incorporated into batteries that can provide high energy density.

The component (A) is a polymer compound containing a repeating unit-a having a structure selected from an ammonium salt, a sodium salt, a potassium salt, and a silver salt of any of fluorosulfonic acid, fluorosulfonimide, and N-carbonyl-fluorosulfonamide. Thus, the present invention provides a bio-electrode composition capable of forming a living body contact layer for a bio-electrode that is excellent in electric conductivity and biocompatibility, is light-weight, can be manufactured at low cost, and can control significant reduction in the electric conductivity even when the bio-electrode is wetted with water or dried; a bio-electrode including a living body contact layer formed of the bio-electrode composition; and a method for manufacturing the bio-electrode.

摘要： Provided is a Li+battery comprising an anode comprising an anode active material comprising a plurality of transition metal (TM1)-substituted binary transition metal (TM2) oxide nanocrystals, a cathode in electrical communication with the anode, a separator between the anode and the cathode, and an electrolyte in contact with the anode and the cathode. The anode active material, in a lithiated state, is characterized by a three-dimensional network of the TM1 and nanoparticles of Li2O and nanoparticles of the TM2, both types of nanoparticles distributed throughout the network. In a delithiated state, the anode active material is characterized by the network of the TM1 and nanoparticles of an oxide of the TM1 and nanoparticles of an oxide of the TM2, both types of nanoparticles distributed throughout the network. The TM1-substituted binary TM2 oxide may be characterized by a ratio of TM2/TM1 of at least about 5.
