Description

MULTI-FUNCTIONAL ZINC ION MICRO-BATTERY AND PREPARATION METHOD AND APPLICATION THEREOF
TECHNICAL FIELD The present disclosure belongs to the field of a micro- battery, and particularly relates to a multi-functional zinc ion micro-battery and a preparation method and application thereof.
BACKGROUND ART In a modern society, there are increasing needs in smart wearable equipment and a flexible electronic product. Such prod- uct, generally, needs to meet requirements of diversified shapes and an excellent flexibility. A variety of products, such as a flexible display, a flexible electronic skin, a smart electronic clothing, and smart wearable equipment, emerge in endlessly. With a development of these emerging industries, a requirement on a flexible electronic device is higher and higher. Although tradi- tional energy storage devices, such as a lithium ion battery, an alkaline zinc-manganese battery, and a lead acid battery, are high in an energy density, such traditional energy storage elements fail to supply an energy to the flexible electronic device direct- ly due to a large volume, a large weight, a fixed shape, and other defects which are difficult to overcome. Therefore, there is a need for an element that can provide the energy for these newly- developing products effectively in the society. Therefore, it is inevitable for an emergence of a flexible micro-battery. As a lithium ion battery technology has been developed ma- turely, a researcher is developing a lithium ion micro-battery taking an organic electrolyte as a substrate with great efforts. Although a certain progress has been made, there still be a lot of defects that should be noticeable in the lithium ion micro- battery. For example, as an organic solvent is used as the elec- trolyte, the lithium ion battery is flammable, volatile, and tox- ic, and have other safety problems; and due to a low natural con- tent of a lithium metal, costs for a mass production of the lithi- um ion batteries are high. In view of the above, developing the micro-battery with a high energy density, a high flexibility, a high safety, a small volume, high temperature resistance, and a low cost has been extremely urgent. For example, a paper “Scalable fabrication of printed %Zn//MnQ, planar micro-batteries with high volumetric energy density and exceptional safety (Xiao Wang, Shuanghao Zheng, Feng Zhou et al .NATIONAL SCIENCE REVIEW, 2020,7,64-72)" discloses a planar printed zinc ion micro-battery. A volume specific capacity of the zinc ion micro-battery can be up to 19.3 mAh cm™, and a maximum energy density can be up to 17.3 mWh cm™. There are still several defects in a technology disclosed in the literature: (1) a prepa- ration process of a Zn//MnC, planar micro-battery is complex, and high in a cost; (2) the prepared 2Zn//Mn0: planar micro-battery is low in a specific capacity, and can’t provide an energy for the electronic device continuously due to the insufficient energy den- sity; and (3) the prepared Zn//Mn0; planar micro-battery can’t be applied in more application scenes due to lack of characteristics of temperature resistance and damage prevention.

In a test, the micro-battery in the present disclosure can operate normally under multiple complex conditions by excellent characteristics, that is, flexibility, temperature resistance, and self-sealing. Scenes of several applications were as follow: (1) Flexible wearable equipment has been popularized in the market. As such new electronic equipment can’t be powered easily by the traditional battery, a flexible battery is developed. For the micro-battery in the present disclosure, parameters were not changed significantly under the bending angle ranging from 0° to 150°, making it withstand an external extrusion force in most cas- es. With the excellent flexibility and an excellent bendability, not only the micro-battery can be used for a wearable electronic product, but can also achieve a powerful promoting effect on a quietly emerging smart clothing industry.
(2) For a natural reason, most of products can’t operate in a constant-temperature environment all the time in life, and thus, there is a requirement that the products should operate normally within a certain temperature range. Obviously, the micro-battery in the present disclosure meets this requirement. As shown in the Fig. 9, the micro-battery can operate normally at the ambient tem- perature ranging from 25°C to 100°C.
(3) There is a possibility of damage and tearing for a flexi- ble product during use, and the micro-battery in the present dis- closure can solve such problem. After being torn, the battery in the present disclosure can continue to operate by bonding in some emergencies, thereby making time for replacing the battery.
It is worthwhile to note that in the technical solution of the present disclosure, although any better using amount is pro- vided, such as the using amount of the TiS; and the MXene, the pre- sent disclosure is not limited to masses of the TiS; and the MXene in the embodiments, since the mass ratio of the MXene to the TiS, ranges from 3: 1 to 3: 5; and the specific using amount depends on actual needs. The technical solution of the present disclosure is not intended to limit the scope of protection of the present dis- closure, but is merely the explanation and illustration for a skilled in the art to learn the technical essence of the present disclosure.
The essential scope of protection of the present dis- closure should be based on the claims.
A skilled in the art should understand that any amendment, equivalent replacement, improve- ment, etc. that are made based on the essence and spirit of the present disclosure should fall within the essential scope of pro- tection of the present disclosure.
