If the current electronic equipment, especially smartphones, notebooks and Other products are the most unsatisfactory, the battery life will be one of the most vomiting places. In order to take care of the performance of the mobile phone, the heat dissipation design must be compromised. The root cause of the battery life is still battery technology. Lithium batteries have been developing for so many years, and energy density and fast charging still have bottlenecks. To completely solve them, new battery materials are needed. Researchers at IMEC Belgium Microelectronics Center have announced that they have developed a new type of 3D nano mesh material, which has achieved an unprecedented surface area ratio. The surface area of ​​a can of beverage-sized material can be as large as that of a football field. This material can be realized for lithium batteries. The higher capacity and charging speed, which can be used as a current collector and catalyst for fuel cells at the same time, and thinner, the key is easier to manufacture. 3D nanomaterials have been a hot topic in materials science research in recent years, because this material has a larger specific surface area and is widely used. IMEC Belgium Microelectronics Center is not only an important base for semiconductor process research, but also has a deep academic foundation in materials science. This time, they jointly developed this new type of nano-net material with KU Leuven and EnergyVille of the University of Leuven, which is equivalent to a can. In objects that are soda-sized and 75% empty, the surface area spread is equivalent to that of a football field, and the internal and external dimensions can be adjusted at will, which can satisfy almost any possible application field. Since many industrial applications rely on chemical reactions occurring on the surface, the larger the available surface area, the more reactions that can occur simultaneously, so this material is widely used. IMEC pointed out that this material is used in lithium batteries, which can achieve higher capacity and faster charging speed, and it also has a large area and porosity. It is also very suitable for energy storage materials and can be used as a collector in fuel cells. Electrical appliances, catalysts. For example, when electrolyzed water is used to produce hydrogen, this material only needs 1 mm thickness to perform better than the foam ninja material that is 300 times thicker. More importantly, the new nanomesh material jointly developed by IMEC is easier to prepare. This problem is the key faced by almost all nanomesh materials, because the material properties of experimental research and development are very good. Once there is no possibility of industrial production, it is often It is purely academic. According to IMEC data, their nanomesh material can be manufactured by inexpensive anodizing and electroplating processes, and compared with its closest competitors (metal foam, aerogel), this material also has a certain flexibility, The other two materials are either too hard or brittle.
