  • Patent number: 11650113
    Abstract: A torque-sensor strain beam structure and a torque sensor are provided. The torque-sensor strain beam structure comprises an external ring, a connecting hub and at least two strain beams. The external ring has a first joint. The connecting hub is located in the external ring and arranged coaxially with the external ring. The connecting hub has a second joint. A first end of each of the at least two strain beams is fixedly connected to an inner wall of the external ring and a second end of each of the at least two strain beams is fixedly connected to the connecting hub. A strain grid is provided on each of the at least two strain beams. A load inputting point is located at the first joint or the second joint. Arrangement of the torque-sensor strain beam structure allows the torque sensor to have smaller volume while having higher measurement sensitivity.

  • Publication number: 20200028159
    Abstract: The present invention provides a carbon-lithium composite powder and a preparation method thereof. In the present invention, a carbon material is used as a skeleton to support metal lithium, which increases the specific surface area of the composite powder, and can effectively reduce the current density and stabilize the surface potential of an electrode, thereby effectively inhibit the growth of lithium dendrites during the process in which the metal lithium is used as an anode material. The present invention provides a method for preparing a lithium metal secondary battery electrode. In the present invention, a roller-press flaking process is adopted to prepare the electrode, such that it is easy to regulate the effective capacity of the metal lithium loaded on the current collector, thereby better matching the corresponding active cathode material to improve the effective utilization rate of the metal lithium.
