  • Patent number: 11897172
    Abstract: A polar plate is fabricated. The polar plate is flexible and made of a plastic graphite composite. No matter a supporting member is used for calendering or not, a thin polar plate with controllable thickness is fabricated. The polar plate is excellent in blocking the through-transmission of vanadium ions and the limit of blending ratio of conductive carbon is broken through. The longitudinal through-transmission volume resistivity (proportional resistance to thickness) is greatly improved by adjusting the blending ratio of conductive carbon for meeting the demand of conductivity. In the mean time, the present invention strengthens the rigidity required for the thin polar plate while providing large-area polar plate fabrication for industrial use and convenience and provides a cooling and pressing method for patterning a composite polar plate. An integrated mold is thus obtained to replace the conventional polar plate which needs to be processed and prepared with runner.

  • Publication number: 20230072808
    Abstract: A method is provided to optimize the surface of a carbon electrode for flow battery. A reaction solution is prepared as containing a requested ratio of functional group. After spraying the reaction solution on the carbon electrode, a number of related parameters of an atmospheric plasma are set for activation the carbon electrode. Thus, the functional group is covalently bonded on the surface of the carbon electrode according to requirement. Thereby, an accurate control of the type and number of the functional group bonded on the surface of the carbon electrode is achieved with the stability and performance of flow battery further enhanced.

  • Patent number: 11327117
    Abstract: An apparatus is provided for measuring the power of electrolytes at different positions of a flow battery by switching six-way valves without reconnecting channels. With the measurements at the positions, weighting is processed to obtain power corresponding to charging statuses for determining accurate power. The charging and discharging of voltage and current of the battery are controlled for constant operations with high efficiency. Consequently, the efficiency of power conversion is improved; energy consumption is reduced; and the battery is always run within a safe power-range for avoiding accidents or damages to the battery. In addition, the present invention is further applicable to a device monitoring the features of a battery unit. The six-way valves online monitor the power at center positions by switching. The values measured at different positions are aimed at the abnormality of the battery unit for processing adjustment or offline replacement to maintain best operation performance.

  • Publication number: 20220085389
    Abstract: A method is provided to fabricate electrode used in super-thin flow-battery. A semi-finished cured film is prepared though colloid-mixing, impregnating, and baking. The film is pressed with different materials for fabricating various types of polar plate according to applications. Thus, a thin electrode is fabricated to contain a supporting member with thickness controllable. The electrode obtains excellent resistance to the permeation of vanadium ions; vertical-penetration volume resistance is controlled by adjusting the blending ratio of carbonaceous matter; and the demand of conductivity is met. Besides, the film is prepared to obtain a bipolar plate, a copper-containing current-collecting end plate, or other electrode material like carbon felt, carbon paper, etc. to be combined into an integrated electrode mold.
