Description

technical field [0001] The invention belongs to the field of micro batteries, and in particular relates to a multifunctional zinc ion micro battery and its preparation method and application. Background technique [0002] The demand for smart wearable devices and flexible electronic products in modern society is increasing. Such products usually need to meet the requirements of shape diversity and good flexibility. Various products such as flexible displays, flexible electronic skins, smart electronic clothing, and smart wearable devices are emerging in an endless stream. The development of these emerging industries has higher and higher requirements for flexible electronic devices. Although traditional energy storage devices such as lithium-ion batteries, alkaline zinc-manganese batteries, and lead-acid batteries have high energy density, their defects such as large volume, heavy weight, and fixed shape are difficult to solve for a while. As a result, these traditional ene...
