  • Patent number: 12145887
    Abstract: The present invention discloses a multiphase ceramic material with a giant dielectric constant, wherein the multiphase ceramic material has a general formula of AxBnxTi1?(n+1)xO2; wherein A is at least one selected from the group consisting of Nb, Ta, V, Mo, and Sb, B is at least one selected from the group consisting of In, Ga, Al, Co, Cr, Sc, Fe (III), and a trivalent rare-earth cation; n is a molar ratio of B to A, 1<n?5, 0<x?0.1. The multiphase ceramic material possesses outstanding properties including a giant dielectric constant, a low dielectric loss, and excellent frequency- and temperature-stability. In particular, it exhibits a high insulation resistivity of higher than 1011?·cm and a high breakdown voltage, which implies it can be applied in high-energy storage devices and supercapacitors. This invention also provides a method to synthesize the multiphase ceramic material.

  • Patent number: 12095130
    Abstract: Systems and methods are provided for mechanical pretreatment of bipolar plates, for example, for plating electrodes in redox flow batteries. In one example, a method for disrupting surfaces of a bipolar plate may include pressing the bipolar plate between imprint plates, and removing the pressed bipolar plate from the imprint plates prior to use in a redox flow battery. In some examples, the pressed bipolar plate may include negative indentations from at least one of the imprint plates. In some examples, the imprint plates may be patterned meshes, such that the negative indentations may include patterns of asymmetric protrusions. In this way, the bipolar plate may be pretreated via pressing so as to reduce wear to manufacturing equipment (relative to other mechanical pretreatment processes, for example) while maintaining electrochemical performance of the redox flow battery.

    Abstract: Provided are a mixed cathode active material having improved power characteristics and safety, and a lithium secondary battery including the same. More particularly, the present invention relates to a mixed cathode active material which may assist power in a low SOC range to widen an available state of charge (SOC) range and may simultaneously provide improved safety by blending substituted LFP, in which operating voltage is adjusted by substituting a portion of iron (Fe) with other elements such as titanium (Ti), in order to prevent a rapid increase in resistance of manganese (Mn)-rich having high capacity but low operating voltage in a low SOC range (e.g., a SOC range of 10% to 40%), and a lithium secondary battery including the mixed cathode active material.

  • Publication number: 20140192592
    Abstract: The present invention relates to an Sb—Te—Ti phase-change thin-film material applicable to a phase-change memory and preparation thereof. The Sb—Te—Ti phase-change memory material of the present invention is formed by doping an Sb—Te phase-change material with Ti, Ti forms bonds with both Sb and Te, and the Sb—Te—Ti phase-change memory material has a chemical formula SbxTeyTi100-x-y, where 0<x<80 and 0<y<100-x. When the Sb—Te—Ti phase-change memory material is a Ti—Sb2Te3 phase-change memory material, Ti atoms replace Sb atoms, and phase separation does not occur. In a crystallization process of an Sb—Te phase-change material in the prior art, gain growth dominates, so the phase change rate is high, but the retention cannot meet industrial requirements.
