preparation example

[0116] Preparation Example: Preparation of Solid Electrolyte - Polyvinyl Alcohol-Potassium Chloride Composition

[0117] Dissolve 10 g of polyvinyl alcohol in 10 mL of aqueous solution, heat at 85° C., and stir for 2 h to obtain an aqueous solution of polyvinyl alcohol.

[0118] Dissolve 8.5g of potassium chloride in 8.5mL of aqueous solution, heat at 80°C, and stir for 2h to obtain an aqueous solution of potassium chloride.

[0119] The potassium chloride aqueous solution is added to the polyvinyl alcohol aqueous solution to form a mixed solution of polyvinyl alcohol-potassium chloride composition.

[0120] The mixed solution of the polyvinyl alcohol-potassium chloride composition was dried under vacuum at 50° C. for 2 hours to obtain a polyvinyl alcohol-potassium chloride composition, that is, a solid electrolyte.

Embodiment 1

[0122] This embodiment provides a battery that can indicate battery power and energy storage status according to color change, and its preparation method is as follows:

[0123] S1. As shown in Figure 1 (a), provide FTO film (fluorine-doped tin oxide) as the first substrate 1, adopt solvothermal method to grow W on the first substrate 1 18 o 49 As the first active material layer 2 , it is annealed by Ar atmosphere; a second substrate 3 of FTO film is provided, and a metal aluminum foil is set on the second substrate 3 as the second active material layer 4 . It can be understood that, in this embodiment, the metal aluminum foil only partially covers the second substrate, but when other electrochromic materials and conductive composite materials are used as the second active material layer, as shown in Figure 1(b), it can also be The second active material layer 4 is completely covered on the second substrate 3 .

[0124] S2. If figure 2 As shown, the electrolyte 5 is applied...

Embodiment 2

[0130] The difference between this embodiment and embodiment 1 is that in the battery manufacturing method, step S3 only partially seals the edge of the battery.

[0131] The battery in this embodiment can also realize self-charging. Specifically, since only the edge of the battery is partially sealed in this embodiment, the battery can be charged by the contact between air and the battery. Use air to charge the battery three times, the capacity of the battery is about: 100mAh / g, specifically as Figure 4 shown.

Abstract

The invention relates to a battery and a fabrication method, charging method and application thereof. The battery comprises a first substrate and a first active material layer, an electrolyte, a second active material layer and a second substrate which are sequentially arranged on the first substrate, at least one of the first substrate and the second substrate employs a transparent conductive material, at least one of the first active material layer and the second active material layer employs a combination of one or more of an electrochromic material, a photochromic material and a thermochromic material, and potential difference is generated between the first active material layer and the second active material layer. By the battery, the electric quantity of the battery can be indicated according to color change of the battery so that the battery is endowed with more intelligence; and moreover, the battery also has the characteristics of rapid self-charging and high capacity and has the advantage that a traditional battery does not have.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to a battery, a preparation method and a charging method thereof, and an application of the battery. Background technique [0002] As a convenient energy storage tool, batteries play an important role in daily production and life. In the past few decades, people's research on batteries has focused on high power, high energy, miniaturization, and long life cycle to solve the optimization problem of energy storage systems. [0003] Taking lithium-ion polymer battery as an example, as one of the most commonly used batteries, research on lithium-ion polymer batteries is mainly to increase battery capacity to prolong power supply time, for example, Chinese patent 201210507690.0 discloses a composite graphite for high-capacity lithium-ion batteries The negative electrode material and the preparation method thereof improve the energy density per unit volume of lithium-ion ba...
