摘要:
Co3O4 nanocubes as can be homogeneously assembled on a few-layer graphene sheet, such a composite as can be used in conjunction with an anode and incorporated into a high energy lithium-ion battery.
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 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.
