At the "Nissan: Towards the Future" global press conference held at the end of November last year, Nissan announced its 2030 vision, planning to invest 2 trillion yen (total 100.88 billion yuan) in the next five years to accelerate the electrification and technology of its automotive product line Speed ​​of innovation, Nissan will launch 23 new electric vehicle models by fiscal 2030, aiming to achieve more than 50% electrification mix of Nissan and Infiniti brands globally. In addition to plans to brin

As an industry observer of the lithium battery industry for more than ten years, I have witnessed several ups and downs of the lithium battery industry, and also formed an industry analysis framework based on technology, output, supply chain, capital and competition pattern. Looking back on the first quarter of this year, the lithium battery industry was bustling with excitement, but it was basically in line with expectations. Since the end of last year, this official account has continued to emphasize the de

Scientists have been actively looking for new ways to shorten the charging time of electric vehicles. Recently, the team of Academician Yu Shuhong from the University of Science and Technology of my country, in cooperation with the team of Professors Yao Hongbin and Ni Yong, is committed to solving the contradiction between high energy density and fast charging performance of lithium batteries, and has proposed and prepared a new type of double gradient graphite anode material. The lithium battery charges to 60% in

For a long time, in the field of cylindrical 18650 batteries, the industry-recognized capacity limit is 3500mAh. Japanese and Korean companies firmly occupy the high-end market. Only a small number of domestic manufacturers can produce small batches, and there are few breakthroughs. The R&D team of Fujian Dynavolt New Energy Technology Co., Ltd. (hereinafter referred to as "Fujian Dynavolt New Energy"), a wholly-owned subsidiary of Dynavolt Technology, has overcome difficulties and has been determined

Researchers at Argonne Labs and collaborating institutions point to 'Aggregates' for future battery performance. Keeping track of the latest scientific literature is an important part of a scientist's job, from which scientists can generate insights that may translate into major advances in the future. This figure shows the aggregates of the battery electrolyte. (Image courtesy of Argonne National Laboratory) In 2018, Lei Cheng, a battery chemist at the U.S. Department of Energy's (DOE) Arg

On September 24th, Great Wall Motor revealed the concepts and innovative technologies of Dayu battery technology in detail for the first time. Cao Yongqiang, Technical Director of Dayu Battery of Great Wall Motors, said that Dayu battery technology is based on the concept of "Dayu water control, better to sparse water", "change blocking to dredging", and adopts the core technical principle of "control + conduction = communication" to build 4 layers The 5-dimensional safety matrix en

Only fight for the day and night, reveal the list and take the lead. Changsha's 22 emerging and advantageous industrial chains dance strongly, becoming the main battlefield for the implementation of the "three highs and four new" strategy. Red Net Changsha Station plans the "Commanding Heights - Changsha Industrial Chain Contributions "Three Highs and Four New" Series Reports", focusing on the leading industries in the country and the world's first-class among the 22 industrial

In order to accelerate the development of new energy vehicles and promote the adjustment of energy structure, the Shanghai Municipal People's Government and CATL signed a strategic cooperation framework agreement in Shanghai on August 18. Comprehensively deepen cooperation in the field of new energy According to the "Shanghai Announcement", on the 18th, Li Qiang, Secretary of the Shanghai Municipal Party Committee, met with Zeng Yuqun, Chairman of CATL, and his party. Deputy Secretary of Shangha

After electric vehicles, the concept of electric aircraft has also entered people's field of vision. So what kind of batteries should the plane carry? According to Japanese media news on November 16, Japanese battery company GSYUASA and Kansai University have jointly developed a light-weight high-energy-density lithium-sulfur battery with a mass and energy density that can reach nearly that of existing lithium batteries. double. Relevant data show that a high energy density lithium-sulfur battery is a bat
