Problems solved by technology

[0002] The cost of common lithium-ion batteries is high, especially the price of lithium cobaltate; the compatibility with ordinary batteries is poor, because the single voltage of lithium-ion batteries usually reaches 3.6V, which is too high for some devices; Lithium-ion batteries often have the risk of leakage, which is harmful to the human body and the natural environment.
In addition, because lithium-ion batteries usually use organic electrolytes as solvents, they may even burn and explode when used improperly.
[0003] Because the button battery usually adopts a metal case, it has the characteristics of poor flexibility and non-bendability

Abstract

The invention relates to a water-activated battery capable of being directly contacted with human skin, which comprises a non-woven fabric base material, a current collector, a positive electrode, a negative electrode and a non-woven fabric packaging layer, wherein the current collector is arranged on the surface of one side of the non-woven fabric base material, the positive electrode and the negative electrode are arranged on the current collector, the positive electrode and the negative electrode are not contacted with each other, and the non-woven fabric packaging layer covers the upper layer. The invention also discloses a preparation method and an application method of the water-activated battery.

Description

technical field [0001] The invention relates to the technical field of photoelectric energy, in particular to a water-activated battery that can directly contact human skin. Background technique [0002] The cost of common lithium-ion batteries is high, especially the price of lithium cobalt oxide; the compatibility with ordinary batteries is poor, because the single voltage of lithium-ion batteries usually reaches 3.6V, which is too high for some devices; Lithium-ion batteries often have the risk of leakage, which is harmful to the human body and the natural environment. In addition, because lithium-ion batteries usually use organic electrolytes as solvents, they may even burn and explode when used improperly. [0003] Because the button battery usually adopts a metal casing, it has the characteristics of poor flexibility and inflexibility. With the emergence of flexible electronic devices such as flexible display screens and flexible biosensors, people began to have a fl...
