The research team of Professor Wu Yongzhen and Professor Zhu Weihong of East China University of Science and Technology has made new progress in the preparation of large-area hole extraction layer for perovskite batteries. Relevant research results were recently published in Advanced Functional Materials. Perovskite solar cells are one of the frontier and hot topics in the field of energy research at present. The maximum photoelectric conversion efficiency of small area devices in its laboratory has reached 25.2

In order to realize the large-scale production of fuel power cell technology in China, it is necessary to solve the problem of gas diffusion layer of fuel power cell core material. At present, China mainly relies on imports to solve the problem of gas diffusion layer. Generally speaking, gas diffusion layer is also a bottleneck technology in the development of fuel power cell technology in China. Wang Haijiang pointed out that the hydrogen energy and fuel power cell research team of the South University of Sc

On March 29, at the BYD blade battery announcement meeting, Ouyang Minggao, an academician of the Chinese Academy of Sciences and a professor of Tsinghua University, commented that its safety advantages were obvious, its volume and energy density were high, and the battery cost would also decrease. The blade battery performs very well in the acupuncture experiment. The long battery has a large heat dissipation area, the short circuit circuit of acupuncture is relatively long, and the heat generation capacity is

The Russian President's Commission for Economic Modernization and Innovation and Development announced that the scientific researchers of the Institute of Chemical Physics of the Russian Academy of Sciences have developed an efficient and stable thin film solar cell based on organic semiconductor materials. The organic semiconductor material is composed of conjugated polymers and fullerene derivatives. The research project was completed with the support of the Russian Science Foundation. The results were publis

Lithium-sulfur battery is a secondary battery with sulfur as the positive material and lithium metal as the negative electrode. Its theoretical specific capacity and theoretical specific energy of the battery are 1672 mAh - 1 and 2600 Wh-kg - 1, respectively. It is considered as one of the high-energy lithium secondary battery systems with the most research value and application prospects. However, there are still many problems to be solved for lithium-sulfur batteries at present, such as low cycle life, low utiliz

With the sharp increase in the sales of electric vehicles in China, there is a forecast report that the lithium ion power battery market is entering a golden period. By 2017, the scale of the power lithium battery industry will increase to the current 400%. With such leapfrog scale rise, battery quality has become an unavoidable technical point. Recently, Beijing issued a document to adjust the quality assurance of vehicles and power lithium batteries, in which the quality assurance of key parts such as power lithi

Everyone is paying attention to the development of cell technology, the development level of cell life and safety, but it seems that little attention has been paid to the development level of battery pack (PACK) technology and the application of new technologies. I think this has a great relationship with the current owners and executors of PACK technology. Why should the vehicle manufacturer dominate the battery pack? At present, battery PACK technology is generally implemented by three types of entities: ce

The sales volume of domestic electric vehicles has increased significantly. According to the forecast report, the lithium ion power battery market is entering the golden period, and the scale of power lithium battery industry will increase sharply. With such leapfrog scale rise, battery quality has become a focus of attention. Some insiders believe that how to break through the technical bottleneck and extend the service life of the battery is a common issue faced by the current battery production companies. Bei

For researchers, battery technology is always a difficult problem to overcome completely. On the one hand, they should try to reduce the cost of manufacturing batteries and provide satisfactory battery life. On the other hand, they should ensure the safety of batteries. They are located in the electronic devices that consumers often use on weekdays, which means that accidents such as battery explosion should never happen, Because it may cause serious harm to human body.(Lithium - Ion Battery Equipment) Although
