American scientists develop new batteries with extremely powerful performance, which may be used in space in the future

Batteries have become an indispensable energy tool in people’s daily life. We need batteries for mobile phones, laptops, electric cars and motorcycles. Batteries help us realize the storage and utilization of electric energy. In the pursuit of sustainable development, batteries are considered as an important breakthrough to promote the development of new energy industry. Therefore, if the existing problems of battery development can be solved, it will bring great opportunities for human development. < / P > < p > some time ago, a paper on the development of new batteries appeared in a famous American Journal. The paper indicates that lamarcrisna bertila team from Clemson University has developed a new type of cell based on silicon in cooperation with NASA. According to reports, the battery is lighter in weight and has more energy storage, and it may be used in satellite operation in the future. At present, the artificial satellites hanging over the earth have their own “missions”. Some satellites are responsible for building communication networks, while others are responsible for detecting the earth’s environment. However, all satellites have one thing in common, that is, they carry many professional electronic equipment. If we want to make the satellite work normally, we must make all the electronic equipment in the satellite work, especially the power supply. At present, solar power generation, nuclear power generation and chemical power supply are combined to provide power for satellites, but these batteries have their own limitations. Solar panels can indeed get more solar energy in space, but when the satellite moves to the side of the earth that cannot be illuminated by sunlight, the solar panels will not be able to power normally. The storage capacity of chemical batteries is very limited, so scientists have been working to improve the storage capacity of chemical power sources. In all battery materials, silicon has been favored by scientists because silicon with the same unit mass can store more charge, and the element with the same charge has lighter weight. Therefore, more and more chemical batteries use silicon as raw material. Even so, silicon is not a perfect element. Experiments show that it will decompose when discharging, which makes the discharge efficiency of silicon not high. In order to solve the problem, tibera adopted a new approach. < / P > < p > first of all, the researchers used nanoparticles smaller than the traditional silicon raw material, which made it difficult for silicon particles to decompose into smaller particles when generating electricity. Second, they used carbon nanotubes to make a honey box like structure, and then placed silicon particles in the middle of every two carbon nanotubes. In this case, even if the silicon particles decompose, they will not escape to other spaces, but will be bound to one level. < / P > < p > it has been proved by experiments that the battery developed by bertila team can repeatedly carry out 500 charge discharge cycles, and after 500 experiments, the battery still maintains good stability, which is better than most chemical power sources. If the battery can continue to improve in the later stage, it will have a great application prospect in the aerospace field. In the future, more satellites will be launched by human beings than at present. Therefore, it is crucial to solve the problem of energy supply, and the development of new energy batteries is very important.
