    Abstract: The present disclosure is applicable to the technical field of motors, and provides a motor rotor, a motor, a power assembly, and an electric apparatus, where the electric apparatus includes a power assembly, the power assembly includes a motor, and the motor includes a motor rotor, a stator, and a rotation shaft. The motor rotor includes a mounting frame and a magnet steel mounted to the mounting frame. The mounting frame is provided with a limiting wall for resisting a centrifugal movement of the magnet steel in a radial direction. By providing the limiting wall on the mounting frame, the limiting wall may share the stress of the mounting frame due to the centrifugal movement of the magnet steel in the radial direction, so that the mounting frame may bear a greater stress, thus alleviating the problem that the magnet steel is thrown out when the motor rotor rotates.

    IPC: H01M50/42

    CPC classification number: H01M50/42

    Abstract: The present application relates to the technical field of secondary batteries, and in particular to a binder for secondary batteries and a preparation method thereof, as well as a separator, battery cell, battery and electrical apparatus comprising the binder. The binder for secondary batteries includes a first polymer and a second polymer, the first polymer includes an acrylate copolymer, and the second polymer includes a water-soluble polymer. When the separator is coated, the binder is stirred evenly in water, coated on the separator, and oven dried to form a bonding layer on the separator. The bonding layer includes a side facing the separator and a side away from the separator. The bonding layer is bonded on the separator, and the side away from the separator has no adhesiveness, which facilitates the winding and unwinding of the separator.

    Abstract: An end cover assembly includes an end cover and a current collecting member, and the end cover is provided with a pressure relief structure. The current collecting member is located on one side of the end cover facing the interior of the battery cell and including a current collecting portion and an assembling portion. The assembling portion is located between the end cover and the current collecting portion and is configured to be connected to the end cover and the current collecting portion. The current collecting portion is provided with a pressure relief hole for allowing fluid to pass. First supporting members and a second supporting member are separately arranged on two side surfaces, facing each other, of the end cover and the current collecting portion. Projections of the first supporting members and a projection of the second supporting member are intersected in a thickness direction of the end cover.
