Abstract: Provided are a water-based adhesive and a preparation method thereof, and its use in an anode of a lithium battery. The method for preparing a water-based adhesive includes mixing a surfactant, acrylic acid, acrylonitrile, acrylamide and water to obtain a mixture system; heating the mixture system to a polymerization temperature to obtain a heated mixture system; adding an initiator into the heated mixture system and subjecting a resulting system to polymerization to obtain a linear polymer; adding a cross-linking agent into the linear polymer and subjecting a resulting mixture to cross-linking reaction to obtain a cross-linking system; cooling the cross-linking system after the cross-linking reaction is completed to obtain a cooled cross-linking system; and adjusting a pH of the cooled cross-linking system to 6-7 to obtain the water-based adhesive.

Abstract: A production method includes providing field-effect transistors; irradiating the field-effect transistors; applying a current to drains of the field-effect transistors for a duration; and applying a same voltage to gates and sources of the field-effect transistors. The voltage is a grounding voltage or a reverse voltage. The field-effect transistors can be in a reverse biased state in a case of cut-off, and electron-hole pairs can be generated at an insulating oxide layer and at an interface between the insulating oxide layer and a semiconductor substrate.
