Abstract: Disclosed is a system for managing a vehicle battery that is chargeable/dischargeable and stores energy for driving a vehicle driving motor. The system for managing the vehicle battery as disclosed includes a controller that measures a polarization voltage of each of a plurality of battery cells in a vehicle battery after charging of the vehicle battery is terminated, and determines whether each of the plurality of battery cells is abnormal based on the measured polarization voltage.

Abstract: Disclosed are a composite fiber (MXene composite fiber) and a manufacturing method thereof. The composite fibers are manufactured by braiding a MXene-PAN fiber heat-treated with a polymer fiber. The method includes preparing a first dispersion including an MXene compound and a first solvent, preparing a second dispersion including polyacrylonitrile (PAN) and a second solvent, obtaining an admixture including the first dispersion and the second dispersion, obtaining a spun fiber by performing wet-spinning of the admixture, obtaining an MXene-PAN fiber by performing heat treatment of the spun fiber, and obtaining the MXene composite fiber by braiding the MXene-PAN fibers with a polymer fiber. An electrical conductivity of the MXene-PAN fiber is about 0.1 Scm?1 to 1,000 Scm?1.

Abstract: The present disclosure relates to a finger-gripper assembly and a finger-gripper assembly system including the same. The finger-gripper assembly includes a finger and a gripper to which the finger is coupled so as to be removable. The gripper includes an arm, an extender coupled to a lower end of the arm so as to be rotatable about a first axis, wherein the extender extends, from the arm along a second axis that extends in an extension direction and intersects with the first axis, and a connector coupled to a lower side of the extender so as to be movable along the second axis, wherein the connector is connectable to the finger.

Abstract: According to various embodiments, an operation method for determining an abnormality in a battery, the method comprising: acquiring battery information including a representative SOC value of the battery at a specific time point and a parameter value for an equivalent model circuit of the battery; acquiring an OCV deviation tolerance for the battery at the specific time point, predicting a polarization voltage deviation, and measuring a measured voltage deviation based on the battery information; and determining whether the battery is abnormal based on a sum of the OCV deviation tolerance and the polarization voltage deviation, and the measured voltage deviation, and a device thereof may be provided.

Abstract: The present disclosure provides a method for surface modification of a titanium implant material and a titanium implant obtained by the method for surface treatments. A titanium implant according to one embodiment of the present disclosure has high bond strength between implant and bone and its corrosion resistance.

Abstract: A gripper includes a base unit and finger units coupled to a protruding direction-side of the base unit. Each of the finger units includes a first link structure coupled to the base unit, a second link structure rotatably coupled to the first link structure, and a third link structure rotatably coupled to both the first link structure and the second link structure, and the second link structure includes a finger tip. When the finger unit is pressed in the protrusion direction, the finger tip is brought closer to the base unit in the protrusion direction by the first link structure. When the finger unit is further pressed in the protrusion direction, the finger tip is rotated to be oriented in a direction opposite to the protruding direction in a state in which the finger tip is oriented in a gripping direction that is a direction perpendicular to the protruding direction.
