Abstract

The invention discloses a rechargeable aluminum ion battery and a preparation method thereof, and belongs to the technical field of batteries. The rechargeable aluminum ion battery can be widely used in the electronics industry and communications industry, and can also be used as a power battery for an electric vehicle. The invention provides a novel aluminum ion battery device, especially a soft bagged battery. The aluminum ion battery device adopts a membrane to separate the positive and negative electrodes of the aluminum ion battery, and uses an insulating soft bag to wrap the positive and negative electrodes of the aluminum ion battery; the enclosed battery is assembled in a shielding gas atmosphere, and only the positive and negative electrode leads which are conductive are exposed for being connected with an external circuit; according to different electrode making technologies, the battery can be assembled into square or round or other shapes. The soft bagged aluminum ion storage battery provided by the invention has the benefits that the capacity is high, the charge and discharge efficiency is high, the cycling stability is good, and the charge and discharge features are excellent; in addition, the electrode materials are extensive in source, and the battery is easy to prepare, low in cost, green and environment-friendly, and low in price.

Description

Technical field [0001] The invention relates to a rechargeable aluminum ion battery and a preparation method thereof, in particular to a soft-packed aluminum ion battery, which can be used as a new type of green energy battery in the fields of electronics industry, communication industry and electric vehicle power battery. Background technique [0002] Currently, non-renewable fossil fuels such as coal, oil, and natural gas are increasingly depleted, and environmental pollution and the greenhouse effect are increasing. Energy crisis and environmental protection have become two major problems facing the world. Therefore, the development of new green energy and energy storage equipment has attracted more and more attention. Since the Japanese SONY company successfully launched lithium-ion batteries, lithium-ion batteries have quickly been widely used in electronic products, power energy, and military fields, and are currently developing into the power battery industry of electric v...
