Abstract: The present disclosure relates to a solid-state electrochemical cell having a uniformly distributed solid-state electrolyte and methods of fabrication relating thereto. The method may include forming a plurality of apertures within the one or more solid-state electrodes; impregnating the one or more solid-state electrodes with a solid-state electrolyte precursor solution so as to fill the plurality of apertures and any other void or pores within the one or more electrodes with the solid-state electrolyte precursor solution; and heating the one or more electrodes so as to solidify the solid-state electrolyte precursor solution and to form the distributed solid-state electrolyte.

Abstract: A background offset drift calibration circuit and method for comparator are proposed. The background calibration circuit and method are designed based on the approximate linear characteristic of the offset drift of a comparator caused by the variation of temperature and power supply. The calibration circuit for the comparators obtains the offset drift characteristic of each comparator by performing twice foreground calibration and selects the comparator with the largest drift as the reference comparator and other comparators as working comparators. The reference comparator is configured to track the offset drift and trigger the background calibration circuit of other working comparators. The working comparators compensate for the offset drift caused by the temperature or the power supply in the background by linear interpolation based on the offset drift characteristic of each comparator.

Abstract: The present invention discloses a carbon fiber composite material boom, a production method thereof, and a truck-mounted concrete pump comprising the carbon fiber composite material boom. The production method of the carbon fiber composite material boom comprises: a flexible airbag is inflated to form an airbag in a first state and a carbon fiber prepreg is laid on the outer surface of the airbag in the first state to obtain a first transitional component; the first transitional component is put into a box-shaped mold and the airbag in the first state is inflated; the carbon fiber prepreg is compressed and shaped to obtain a second transitional component; the second transitional component is heated up and solidified, and cooled and de-molded after being solidified to obtain the carbon fiber boom.

Abstract: The disclosure provides a concrete pumping equipment and a bending connecting rod device thereof, and a manufacturing method for the device. The bending connecting rod device comprises a shaft sleeve, at least two composite support plates and cover plates, wherein the at least two composite support plates are provided with holes, the shaft sleeve is embedded in the holes, and the at least two composite support plates are arranged on the shaft sleeve at intervals; and the cover plates are fixedly arranged at the ends of the shaft sleeve. Through the disclosure, the bending connecting rod is formed by thermally pressing and solidifying the composite support plates and the shaft sleeve embedded in the composite support plates, so as to have the characteristics of light weight, and high strength, corrosion resistance and designability.
