Green energy-storing thin-film battery and producing method thereof

Abstract

The new type of film cell has film energy storing system based on meal aluminum and iodine. The film cell can provide low current density of microampere / sq cm level, discharge platform of 400-1000 mV and discharge capacity of 100 microampere.hr / sq cm level. The I2 / A film cell may be prepared in large scale and simple process, and has light weight, no toxicity, low cost, environment friendship and other advantages. It may be used as the power source in artificial pacemaker, intelligent card, implantable medical device and MEMS. Furthermore, I2 / A film cells may be connected parallelly or serially to constitute power supply with great capacity and wider application.

Description

technical field [0001] The present invention discovers thin-film batteries based on aluminum and iodine for the first time. Because they are green materials, thin-film batteries can be easily prepared and can replace other current batteries. Background technique [0002] With the miniaturization of electronic devices, especially as power sources in pacemakers, smart cards, implantable medical devices, and micromechanical systems (MEMS), various thin film batteries are required to match the miniaturization of these devices. Typically, a thin-film battery includes a cathode current collector, a cathode, an electrolyte, an anode, an anode current collector, and even a protection layer. They are built on a substrate. Therefore, the preparation of a thin-film battery is very complicated, which increases the cost of their application. Many efforts are focused on designing new thin-film batteries. Especially in the new century, the demand for energy will increase sharply. Design...
