Abstract: Provided is a method for extracting and recovering high-purity lithium carbonate and iron phosphate from a spent lithium battery material. The method includes the following steps. In a first extraction stage, the iron phosphate feature data is input into an iron phosphate quality analysis model to obtain a first quality index at time T1+a. Whether the extraction device is in an abnormal extraction state at time T1+a is determined. If the abnormal extraction state occurs, an extraction adjustment instruction is generated, and the extraction device is adjusted. If not, a second extraction instruction is generated, and whether the extraction device is in an abnormal state at time T2+b in a second extraction stage is determined. If the extraction device is in the abnormal extraction state, a second extraction adjustment instruction is generated, and the extraction device is adjusted. If not, extraction continues until extraction of lithium carbonate is completed.

Abstract: A battery module, a battery, and a power-consuming apparatus are disclosed. The battery module includes a battery group, an end plate arranged on a side of the battery group in a first direction, and an insulation member positioned between the battery group and the end plate. An avoidance region is formed at a corner of the end plate, and a corresponding corner region of the insulation member is fixedly connected to the battery group. This configuration reduces warping or separation of the insulation member at the corner, enhances structural stability between the insulation member, end plate, and battery group, and minimizes interference with the end plate assembly region. As a result, the assembly difficulty of the battery module is lowered and the assembly quality is improved.

Abstract: A joint k-space and image-space reconstruction imaging method and a device, relating to the field of magnetic resonance imaging. The method comprises: first, using the k-space parallel imaging method to reconstruct under-sampled image frames having auto-calibration signals of a subject obtained from multi-frame imaging required for the measurement of magnetic resonance parameters; and then performing reconstruction in image space for other under-sampled image frame data without auto-calibration signals. In the method, an accurate sensitivity map required for the SENSE method is generated from under-sampled data, without the need of additional acquisition. By means of the present method, images that are almost identical to those obtained by the traditional GRAPPA method and without obvious artifacts can be obtained at a speed which is four times faster than that by the traditional GRAPPA method.

Abstract: The present disclosure provides a respiratory syncytial virus-based adenovirus vector vaccine, a method for preparing same, and use thereof. Specifically, an adenovirus vector suitable for a transmucosal formulation against RSV is selected from a variety of adenovirus vectors. The vaccine is administered by inhalation, which can simulate the virus infection process, stimulate the immune response, and avoid local adverse effects such as injection site pain and the like due to intramuscular injection. By means of inhalation, the atomized vaccine can finally reach the lung through the respiratory tract, thus inducing the respiratory tract mucosal immunity while stimulating the humoral immunity and cellular immunity. The stimulation of the pulmonary mucosal immunity is the most effective method for preventing RSV infection and spread. The vaccine stimulates the lung mucosal immunity and exhibits a well induced humoral immunity level.
