Abstract: Disclosed is a method for leaching lithium via an electrochemical apparatus including a multi-functional current collector, an electrode, an electrolyte, and a lithium-bearing material, wherein the lithium-bearing material is dispersed or suspended in the electrolyte or the lithium-bearing material is coated onto the current collector. The method involves applying voltage to the current collector to leach lithium from the lithium-bearing material. The method can involve adding promoter additive into the electrolyte to boost lithium extraction within the electrochemical apparatus.

Abstract: The present disclosure provides a lidar system. The lidar system includes: an optical rotating mirror and at least two laser transceiving modules. Each laser transceiving module includes a transmitting unit and a receiving unit. The transmitting unit is configured to transmit a laser signal. The optical rotating mirror is configured to rotate around a rotating axis in a vertical direction, receive the laser signal and adjust a direction of the laser signal during rotation, and reflect the laser signal to a target object. The laser signal is diffusely reflected on the target object, which produces an echo signal. The echo signal is reflected by the optical rotating mirror and is then received by the receiving unit. The receiving unit includes a plurality of detectors arranged in an array.

Abstract: A method and a system for optically adjusting an image fusion LiDAR system are provided. The method includes: presetting initial positions of a first detector and a second detector; acquiring signal strengths of the echo signals emitted by diffuse reflection at different positions on a background wall detected by the first detector; determining a first mark position on the background wall according to the signal strengths of the echo signals; and adjusting at least one of a position or an attitude of the second detector according to an echo signal emitted by diffuse reflection at the first mark position, the first detector and the second detector being each a linear array detector.

Abstract: A method and a system for optically adjusting an image fusion LiDAR system. The method includes: presetting initial positions of a first detector and a second detector (101); acquiring signal strengths of the echo signals emitted by diffuse reflection at different positions on a background wall detected by the first detector (102); determining a first mark position on the background wall according to the signal strengths of the echo signals (103); and adjusting at least one of a position or an attitude of the second detector according to an echo signal emitted by diffuse reflection at the first mark position (104), the first detector and the second detector being each a linear array detector. The method does not depend on mechanical precision processing and ensures that a photoelectric detector and an image detector detect the same object at the same moment in an image fusion LiDAR system to ensure time synchronization precision.

Abstract: The present invention provides a fin and a heat sink. The fin includes a body having at least one first through-hole and at least one first protrusion. The first protrusion extends from the first through-hole toward one side of the body to form a first protruding end. At least one first notch is provided on the body in communication with the first through-hole. The fins are stacked up to form a fin set. A first heat pipe penetrates the fin set to constitute the heat sink. The first heat pipe penetrates the first through-hole while the first notch is expanded, so that the first protruding end tightly abuts against the first heat pipe. In this way, the structural strength of the fin is improved, the first heat pipe is protected from wearing due to the rubbing of fins against the heat pipe, and the heat-conducting efficiency is increased.
