Abstract

The invention discloses super-tensile gel electrolyte ink suitable for aerosol printing and a preparation method of the super-tensile gel electrolyte ink. The gel electrolyte ink is prepared from the following components: a solvent, an electrolyte, cellulose and a cellulose dispersing agent. The super-tensile gel electrolyte ink capable of being used for aerosol printing is prepared according to a certain proportion and a specific adding sequence. The ultrathin and super-tensile gel electrolyte can be prepared by using an aerosol printing method based on the ink prepared by the invention, and compared with the existing electrolyte, the electrolyte prepared by aerosol printing based on the electrolyte ink formula disclosed by the invention is controllable in thickness, can meet the ultrathin and super-tensile characteristics at the same time, and is suitable for flexible metal-air batteries, and the bottleneck problem of preparation of the energy electrolyte of the existing flexible wearable electronic equipment is solved.

Description

technical field [0001] The invention relates specifically to a super-stretched gel electrolyte ink suitable for aerosol printing and a preparation method thereof. Background technique [0002] With the rapid development of flexible and wearable consumer electronics products, conventional cylindrical batteries and button batteries are difficult to meet the special requirements of their mechanical characteristics, and cannot realize flexible functions such as bending and stretching of electronic products as a whole. Aluminum-air batteries are one of the important energy storage devices for flexible and wearable consumer electronics, due to their high specific energy, light weight, and small size, they have attracted extensive attention from researchers. From the perspective of safety, the existing flexible aluminum-air batteries generally use solid gel electrolytes, which can avoid electrolyte leakage and improve battery safety. At present, solid gel electrolytes are mostly p...
