Abstract

The invention discloses a multi-response intelligent zinc-air battery and a preparation method thereof. By mixing a carbon nanotube or graphene with a polymer PEDOT-b-PEO and ultrasonically dispersingthe mixture, a catalyst for preparing a multi-response foam positive electrode is prepared. Further, the multi-response foam positive electrode for the intelligent zinc-air battery is prepared by repeatedly immersing the elastic foam in the dispersion liquid of the catalyst. The multi-response foam positive electrode can achieve multiple responses to pressure, ultraviolet light and sunlight, andcan form the intelligent zinc-air battery with a metal zinc negative electrode and an alkaline polymer gel electrolyte. The method is simple in process, low in production cost and low in environmentalpollution, and is an important innovation in the field of energy devices. Therefore, the multi-response foam positive electrode has a wide application value and prospect in the preparation of intelligent zinc-air battery with multiple responses to pressure, ultraviolet light and sunlight, and other devices or intelligent energy management devices with responses to external stimuli.

Description

technical field

[0001] The invention belongs to the technical field of energy storage batteries. More specifically, it relates to a smart zinc-air battery with multiple responses to pressure, ultraviolet light and sunlight and a preparation method thereof. Background technique

[0002] With the vigorous development of portable and intelligent electronic devices, people's life has been greatly facilitated. In order to further enhance the "human-computer interaction" and meet other special needs of people, it is very important to design energy storage devices with new functions. In addition, systems that can respond to various external environmental stimuli (such as light, heat, magnetism, pH, and force, etc.) have received extensive attention. Stimulus-responsive systems can have good application prospects in sensors, bionic devices and biomedicine. Therefore, if the traditional energy storage device is combined with special response properties, it will endow the traditiona...
