Description

Green energy storage thin film battery and preparation method thereof
Technical Field
The present invention has for the first time discovered thin film batteries based on aluminum and iodine. Because the materials are green materials, the preparation method of the thin film battery is simple, and the thin film battery can replace other current batteries.
Background
With the miniaturization of electronic devices, in particular as power sources in pacemakers, smart cards, medical-implantable devices, micromechanical systems (MEMS), various thin-film batteries are required to match the miniaturization of these devices. Typically, a thin film battery includes a cathodic current collector, a cathode, an electrolyte, an anode, an anodic current collector, and even a protection. They are constructed on a substrate. Therefore, it is very complicated to manufacture a thin film battery, which increases the cost of their application. Much effort has been focused on designing new thin film batteries, particularly in the new century, with a dramatic increase in energy requirements, and designing and developing new environmentally friendly power sources would be a very important technical challenge.
Iodine-based cathode materials have attracted attention in the field of energy storage. Li/Al batteries were first prepared in 1972 and applied to implantable medical devices. The formation of a thin film layer of LiI in real time is used as an electrolyte. Another reported silver/iodine cell is a special silver ion cell, AgI or its mixture as silver ion solid electrolyte.
The thin film batteries have the disadvantages of complex preparation process and high cost.
Disclosure of Invention
The invention aims to provide a green energy storage thin film battery with simple preparation method, low cost and excellent electrochemical performance and a preparation method thereof.
The invention provides a green energy storage thin film battery, which is an aluminum iodine battery, and takes aluminum as an anode, iodine as a cathode and hydrate or solution of aluminum iodide as electrolyte. Because of the strong water absorption of aluminum iodide, aluminum iodide is very easy to hydrate in the air, and an electrode layer is formed.
The invention provides a novel energy storage system, namely a discharge unit is formed by iodine and cheap aluminum.
The aluminum-iodine thin film battery provided by the invention can be prepared by a very simple gas-solid reaction method. It avoids the complex processing process of the traditional battery preparation. The preparation cost is reduced. The preparation method comprises the following specific steps:
iodine is placed in a glass container and an aluminum sheet or film is contacted with iodine vapor. For example, in an iodine-filled glass bottle neck, the surface of the aluminum is facing the iodine. Sublimating iodine at room temperature (10-40 ℃) or under a heating condition, wherein iodine vapor contacts the surface of aluminum, and a simple gas-solid reaction occurs: and reactingfor 3-15 hours, taking out the sample, and placing in the air for 2-6 hours to obtain the needed aluminum iodide thin-film battery.
The surface of the battery film prepared by the invention can be observed by a scanning electron microscope and characterized by electron loss spectroscopy (EDX). As a result, the surface of the thin film battery was found to be very smooth. The EDX result shows that the surface of the film has Al, I, H and O element composition.
Determined by X-ray diffractometer (Rigata/Max-C). The X-ray diffraction pattern shows that the diffraction peaks of the iodine and the aluminum are obtained.
The properties of the thin film battery were measured by the electrochemical workstation Chi660 a. The non-iodinated aluminum metal is connected with iodine on the surface, or other conductive films are attached on the iodine films. The open circuit potential is between 400mV and 1000 mV. The polarization test result shows that the thin film battery can provide low current density at mu A/cm2An order of magnitude. The discharge test result shows that the discharge capacity is 100～102μAh/cm2An order of magnitude range.
These results indicate that the aluminum-iodine thin film battery is a cheap green energy storage battery. The preparation method of the aluminum-iodine thin film battery is simple and easy for large-scale production. The aluminum and the iodine are very cheap, and the method is environment-friendly. It is especially suitable for use as the power source of pacemaker, intelligent card, implantable medical device and micro mechanical system. And various single thin film batteries can be connected in parallel or in series to form a power supply to form a large discharge current or high-power supply, thereby providing large current and high energy.

Leaving a portion of the aluminum free from iodine vapor. At room temperature (10-40 ℃), iodine vapor contacts the aluminum surface and a simple gas-solid reaction occurs: . After 3-12 hours, the sample was removed and left in the air for 2-4 hours.
