Embodiment Construction

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the mode of the present invention includes but not limited to the following embodiments.

[0024] This embodiment provides a compressible and rechargeable zinc-manganese battery, which is composed of a positive electrode, a negative electrode, and an electrolyte containing anions and cations and having ion conductivity. The negative electrode uses an active material mainly composed of zinc, and the positive electrode active material is manganese dioxide. see figure 1 and figure 2 .

[0025]Specifically, the main purpose of this example is to improve the mechanical properties of the polymer electrolyte itself and the battery using the electrolyte, so this example develops and uses a chemically cross-linked polyacrylamide hydrogel as a possible Electrolyte for rechargeable zinc-ion batteries. Compared with common battery separators, polyacrylamide hyd...

Abstract

The invention discloses a compressible rechargeable zinc-manganese battery and a battery-sensor integrated device based on the battery. The compressible rechargeable zinc-manganese battery comprises apositive pole, a negative pole and an electrolyte, wherein the negative pole is made from a zinc element based active material, and a positive pole active material is manganese dioxide; the electrolyte is a crosslinked polyacrylamide hydrogel electrolyte. The synthetic method for crosslinked polyacrylamide hydrogel electrolyte is as follows: 3-5 g of monomeric acrylamide, 25-35 mg of an ammoniumpersulfate initiator and 3-5 mg of N'N-dimethyl bis acrylamide are added into 15-25ml of deionized water, and stirring continues till clarification is achieved; then a clear solution is transferred to a glass watch glass and then is coated with tin foil paper, and reaction is executed at 50-70 DEG C for 50-70 minutes to obtain a hydrogel; finally, the hydrogel is fully soaked in 0.8-1.2 mol / L ofzinc sulfate and 0.05-0.15 mol / L of manganese sulfate electrolyte to obtain the crosslinked polyacrylamide hydrogel electrolyte. The battery can adapt to large compressive stress while maintaining energy storage performance, and flexibility and elasticity of an energy storage device can be achieved.

Description

technical field [0001] The invention relates to a compressible and rechargeable zinc-manganese battery and a battery-sensor integrated device based on the battery. Background technique [0002] In order to realize the power supply for flexible wearable electronic devices, the design and development of flexible energy storage devices has become one of the research directions of new energy storage devices at this stage. However, it is difficult to design elastic energy storage devices based on the electrode / separator / electrode three-layer structure of conventional energy storage devices. Therefore, we need to find new technical paths to realize the flexibility and elasticity of energy storage devices. [0003] Currently, some progress has been made in stretchable energy storage devices based on stretchable electrodes or hydrogel electrolytes, such as stretchable supercapacitors or stretchable batteries. However, the research progress of compressible energy storage devices is...
