A lithium-mediated electrochemical method for ammonia synthesis, relating to the field of ammonia synthesis technology, solves the technical problems of severe side reactions, limited nitrogen mass transfer, and poor interfacial stability in existing lithium-mediated ammonia synthesis systems. Tetra(4-formylphenyl)porphyrin iron and an amino-containing multifunctional organic ligand are added to a mixed solvent of n-butanol and o-dichlorobenzene. An acid catalyst is added, and after stirring until homogeneous, the mixture is degassed and sealed for reaction. The solid product is collected by centrifugation, washed, and dried to obtain COF powder. This powder is then added to an ethanol-water solution, followed by ultrasonic dispersion with Nafion solution. The powder is then drop-coated / sprayed onto the surface of a carbon paper current collector and dried. This powder is used as the working electrode, with a platinum mesh as the counter electrode, a platinum wire as the quasi-reference electrode, and a LiBF4 tetrahydrofuran solution as the electrolyte. Ethanol is used as the proton donor, and electrolysis is performed under a nitrogen atmosphere using a constant current. This invention can be applied to the field of ammonia synthesis technology.

The invention provides battery hoisting equipment for new energy whole vehicle manufacturing in the technical field of battery pack installation. The jacking assembly is installed on the base in a telescopic mode so as to push wheels to lift a vehicle to a preset height; the assembling component is mounted in the middle of the jacking component and is used for positioning the battery to an accommodating space at the bottom of the vehicle according to the parking state of the vehicle; the assembling assembly comprises a vehicle body positioning assembly which is installed on the base and locked on the front surface, the rear surface, the left surface and the right surface of a vehicle body so as to determine the parking direction of the vehicle; the locking and pushing assembly is mounted on the vehicle body positioning assembly; and the vehicle body positioning assembly locks the parking direction of the vehicle. The device has the advantages that the battery pack shell can be quickly and conveniently loaded into the loading space on the vehicle chassis, and the battery pack shell or the loading space cannot be damaged when the battery pack shell is inserted into the loading space.
