Abstract: A method, an apparatus, an electronic device, and a storage medium for detecting water content in a battery are provided. The method comprises: obtaining a capacitance detection value of a battery to be tested by measurement; and determining a first water content value of the battery to be tested according to the capacitance detection value and a capacitance-water content relationship model. The capacitance-water content relationship model is obtained according to the relationship between sample batteries with different water content values and their sample capacitance values. By pre-constructing the relationship between the water content of the sample battery and the sample capacitance value and determining the water content of the battery to be tested according to the relationship and the capacitance value of the battery to be tested, the step of manually cutting the electrode sheet is reduced, and the efficiency of detecting the water content in the battery is improved.

Abstract: A method for preparing voriconazole L-camphorsulphonate and voriconazole. The method for preparing voriconazole L-camphorsulphonate comprises: method 1: dissolving (2R,3S)/(2S,3R) isomer mixture and L-camphor sulphonic acid in water and acetone, and performing crystallisation filtration to obtain voriconazole L-camphorsulphonate; method 2: (a) dissolving a mixture of isomer mixture and L-camphor sulphonic acid in a first solvent and then performing crystallisation filtration; or (a?) dissolving L-camphorsulphonate of the isomer mixture in a first solvent and then performing crystallisation filtration; (b) concentrating the filtrate obtained in step (a) or (a?) into a solid; and (c) dissolving the solid obtained in step (b) in a second solvent and performing crystallisation filtration to obtain voriconazole L-camphorsulphonate. Adjusting the resolution solvent effectively reduces production costs and facilitates recycling of the resolution solvent.

Abstract: Iodonium salt initiator and processing-free thermally sensitive plate precursor containing thereof, and processing-free thermally sensitive plate and use thereof, At least one of two para positions of two benzene rings of the iodonium salt initiator is an alkene group containing a carbon or nitrogen or oxygen atom and a double bond at an end. The alkene group can increase a steric hindrance of the iodonium salt, improves compatibility of the iodonium salt, the thermosensitive resin and the crosslinkable prepolymer, reduces the surface migration of the iodonium salt in the imaging layer and improves the initiation efficiency. During the laser imaging, a double bond contained in a residual end of the iodonium salt can perform a crosslinking reaction with the thermosensitive resin and the crosslinkable prepolymer, and thus reduces damage to the imaging layer caused by small molecules.
