Problems solved by technology

However, the above existing technologies all prepare MWB batteries with a single humidity response capability, which is limited by a single stimulus response capability. In addition, overly active lithium metal is dangerous in daily use and requires additional inert gas protection, which increases the risk and cost of the device

Abstract

The invention discloses a humidity and pressure dual-response metal-water battery and a preparation method thereof. A humidity and pressure dual-response foam positive electrode for a metal-water battery is firstly provided, and a semiconductor polymer with a nitrogen-containing functional group is loaded onto foam through a chemical oxidative polymerization reaction. The foam positive electrode has good porosity, and multiple functions such as integration of a moisture carrier, a hydrogen evolution catalyst and a pressure and humidity dual-response unit on a single electrode are realized; thefoam positive electrode and the active metal negative electrode are directly assembled into a metal-water battery under the condition of not additionally adding an electrolyte and a diaphragm, the metal-water battery can spontaneously control the magnitude of output current under external humidity change and pressure stimulation, and dual response is generated to humidity and pressure; therefore,the metal-water battery prepared by the method has a good application prospect in the field of intelligent electronics.

Description

technical field [0001] The invention belongs to the technical field of energy storage batteries. More specifically, it relates to a metal-water battery with dual response to humidity and pressure and a preparation method thereof. Background technique [0002] With the rapid development of smart electronics and sensor technology, electrochemical energy storage devices with special functions have become increasingly important in human production and life. Among them, smart stimuli-responsive devices, especially those with the ability to sense a variety of environmental changes, are extremely attractive and have potential applications in multiple fields such as sensors, robots, and bionic devices. Some important advances have been made in the research field of introducing functions such as compressibility, photothermal and photoelectric effects, or electrochromism into supercapacitors or batteries. However, most of these devices are limited by a single stimulus response capab...
