Today's lithium batteries have many evidences to prove their shortcomings, which prompted people to consider using too many new materials in such devices. When it comes to anode, the goal is to integrate materials and better charge rate and energy density than commonly used graphite, and find a safe way to use lithium without risking dendrite. Lithium titanate has proved its prospects and has certain commercial value, but the anode made of this material often has lower energy density than graphite and challe

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

With the launch of Fitbit in 2009, wearable devices have also become products for mass consumers. At that time, some people questioned whether consumers really have the need to track their walking steps and heat consumption? However, with the continuous development of wearable technology and wearable devices becoming more and more fashionable and intuitive, this industry has developed rapidly. The global wearable device market is expected to ship more than 126 million units in 2019 (19.6 million units in 2014),

The Kirin battery of CATL (300750. SZ) was finally unveiled. On June 23, CATL officially announced the third-generation CTP (CellToPack) technology, and announced that this new product called "Kirin battery" will be mass produced and launched next year. Li Xiang, CEO of Ideal Motor (02015. HK), forwarded the news released by Kirin Battery on Weibo platform, and commented that "see you next year". The official Wechat of CATL then forwarded Li Xiang's microblog and commented that "K
