This invention discloses a modified polymethylhydrosiloxane electrolyte additive, its preparation method, electrolyte, and applications, belonging to the field of lithium metal batteries. The additive of this invention has a siloxane main chain, with at least one of carbonate and fluoroalkane substituents and an ether substituent introduced into the side chain. This allows the modified polymethylhydrosiloxane, when used as an electrolyte additive, to effectively reduce side reactions between lithium metal and the electrolyte, inhibit lithium dendrite growth, and maintain the crystal structure of the high-nickel cathode, reducing its disintegration and nickel ion deposition. When compounded with carbonate organic solvents as an electrolyte and applied to lithium metal batteries, it effectively improves the cycle stability and coulombic efficiency of lithium metal batteries.

The application discloses an ultrasonic probe, an ultrasonic imaging system and a preparation method. The ultrasonic probe comprises a transducer assembly, and the transducer assembly comprises a matching layer, a piezoelectric layer having opposite first and second surfaces, the second surface of the piezoelectric layer being connected to the matching layer, the piezoelectric layer comprising a plurality of array elements arranged in an array, a flexible circuit board comprising an insulating substrate and a plurality of conductive parts, the insulating substrate being connected to the first surface of the piezoelectric layer, the plurality of conductive parts being arranged on the side of the insulating substrate facing the piezoelectric layer, a backing connected to the side of the insulating substrate away from the piezoelectric layer, a conductive adhesive used for bonding the insulating substrate and the piezoelectric layer, the conductive adhesive comprising a plurality of conductive particles, the conductive particles being used for conducting the array elements and the conductive parts, and a containing structure used for containing the conductive particles and limiting the movement of the conductive particles, the first surface of each array element being provided with the containing structure, so that the first surface of each array element is conducted with one conductive part, and the conduction rate of the array elements is improved.
