1. Introduction to quasi-single crystal technology 1.1 Traditional monocrystalline and polycrystalline silicon technology We understand that single crystal silicon is generally prepared by the Czochralski method (CZ method), seeding with a single crystal seed crystal of a specific crystal orientation, and then rotating and pulling to obtain a single crystal silicon rod of the target crystal orientation. The obtained product only contains A die with low defects and high conversion efficiency. At present, the con

In 1839, fuel cell technology was introduced. In the 1970s, the oil crisis caused an energy panic, and hydrogen energy, as an emerging clean energy source, began to attract the attention of governments around the world. In the 1990s, internationally renowned car companies including Ford and Mercedes-Benz launched fuel-powered cell concept models. After entering the 21st century, the development of hydrogen energy and fuel power cell technology has gradually matured. In the past two years, due to the advantages of h

The lithium iron phosphate battery energy storage system can act as a buffer between various power sources and stable power demand. The wind power generation system software has power oscillation due to the change of wind power generation power. The energy storage system can display the reliability and reactive power compensation of the wind turbine according to the characteristics of the rapid response time of the wind turbine and the same charging cycle. In addition, in the off-grid power generation system softwa

According to foreign media reports, Toyota Motor Group said it plans to develop a more advanced electric vehicle battery in the next few years to help its vehicles increase cruising range by 15% and prolong battery life. Hisao Yamashige, a researcher in battery technology at Toyota, said: "Lithium-ion batteries are the focus of vehicle electrification, and we want to go one step further: improve technology and improve performance." Improving lithium-ion battery performance is a concern for all EV ma

Scientists at the University of Bristol in the United Kingdom have recently used nuclear waste to create a new type of man-made diamond battery. This radioactive diamond battery has a service life of more than 5,000 years. The British already had 95,000 tons of graphite blocks. They collected radioactive "carbon-14" from this nuclear waste to make diamond batteries. According to the researchers, a diamond battery produced in 2016 can take 7746 years to use up half of its energy. Sina Technology News

1. Analysis of flow battery Recently, nanoFLOWCELL, an electric vehicle brand from Liechtenstein, announced the new QUANT48Volt concept sports car, using the latest low-voltage flow battery technology, the maximum power will reach 762 horsepower, the maximum speed of 300km/h, 0-100km/h acceleration 2.4s, the maximum cruising range or Over 1000km. I believe everyone is used to this kind of news, but in fact, for us ordinary consumers, this kind of "surreal concept car" is still far away from us, and th

In life, you may have come into contact with various electronic products, so you may not know some of its components, such as the energy storage battery it may contain, then let Xiaobian lead you to learn energy storage technology together . Energy storage devices composed of energy storage elements and grid access devices composed of power electronic devices have become two important parts of energy storage systems. Energy storage devices are important for enabling energy storage, release or fast power exchange. T

A Canadian battery research team led by Tesla battery expert Jeff Dahn is about to break through the energy density barrier of a new, next-generation battery. The team recently published the discovery in a new paper, Resolving Anode-Free Battery Defects with Electrolyte Solutions. After breaking this barrier, the energy density of next-generation battery cells is expected to reach revolutionary and unprecedented heights. According to the paper, "Diagnosing and Correcting Anode-Free Battery Failure Through E
