Chinese Scientists Invent New Aluminium Battery Aluminum Economy

According to the bulk non-ferrous net reprint: The emergence of new aluminum batteries for the battery industry to bring a major breakthrough, while becoming an economic addition to the aluminum industry. In early April, the research team headed by Professor Dai Hongjie at Stanford University in the United States published a paper on aluminum batteries, which attracted wide public attention. It is reported that this kind of aluminum battery has the advantages of high efficiency and durability, low flammability, low cost, and quick charging, and can be a safe alternative to conventional batteries.

Over the past decade or so, researchers have tried to develop a commercial aluminum battery, but all have failed. The biggest challenge is that it is difficult to find a type that can provide sufficient voltage after repeated charge and discharge cycles. Material. In the first half of 2015, Chinese scientists in the United States finally broke through the bottleneck and developed the first commercially available high-performance aluminum battery.

The battery has three characteristics. First, it uses a flowing liquid as a positive electrode material in the world. Its current and power are large, and it can be used in thousands and ampere-class. Second, aluminum is used as a material to solve the problem of aluminum self-rotation. For the first time in the world, a high-current application of aluminum is realized. Third, no charging piles are required, and only the battery water containing solids needs to be added, which can be free from time and space limitations.

The new aluminum battery supports ultra-fast charging. Taking a smart phone as an example, it takes several hours for the current lithium battery to be fully charged, but the aluminum battery needs only 1 minute to be fully charged. With its advantages of low cost, high safety performance, fast charging, and long life cycle, aluminum batteries have a broad market for 3C consumer electronics products. They can also be used to store renewable energy in the power grid. In addition, they will be prepared in the electric vehicle industry. Favored.

Due to slowing economic growth, overcapacity, and cost reduction, aluminum prices in the international and domestic markets have been operating at low prices, and the aluminum industry has even entered an era of negative profits. It is reported that foreign aluminum consumption is difficult to have a large growth point, developed countries in the United States, Japan, Europe aluminum consumption has entered the platform period, and China's aluminum consumption is also difficult to improve. The research and application of aluminum batteries will once again expand the scope of application of aluminum. In the future, it will vigorously promote the consumption demand of aluminum and inject a chance for the long-absorbed aluminum industry.
