    摘要: A positive electrode material is provided including an electroactive material having one or more phases comprising lithium (Li), an electroactive metal (M), and phosphate (PO4), wherein in the fully lithiated state, the overall composition has a ratio of Li:M ranging from greater than about 1.0 to about 1.3, a ratio of (PO4):M ranging from about 1.0 to about 1.132, M is one or more metals selected from the group consisting of Cr, Mn, Fe, Co, and Ni, and at least one phase includes an olivine lithium electroactive metal phosphate. In some instances, a composite cathode material including an electroactive olivine transition metal phosphate and a lithium and phosphate rich secondary phase is disclosed for use in a lithium ion battery.

    摘要: The synthesis of thiophene based conducting polymer molecular actuators, exhibiting electrically triggered molecular conformational transitions is reported. Actuation is believed to be the result of conformational rearrangement of the polymer backbone at the molecular level, not simply ion intercalation in the bulk polymer chain upon electrochemical activation. Molecular actuation results from π-π stacking of thiophene oligomers upon oxidation, producing a reversible molecular displacement that leads to surprising material properties, such as electrically controllable porosity and large strains. The existence of active molecular conformational changes is supported by in situ electrochemical data. Single molecule techniques have been used to characterize the molecular actuators.
