Graphene, a new material, has attracted global attention since it won the Nobel Prize in 2010. More than 80 countries around the world have invested in the development of graphene materials. The United States, the United Kingdom, South Korea, Japan, Europe and other countries have raised the research on graphene to a strategic height, expecting it to bring huge market value. The industry expects that the annual output of graphene will reach 1000 tons in the next five to ten years. By 2020, graphene industrializatio

On August 23, Hanergy announced that Alta Devices, a wholly-owned subsidiary of the Group in the United States, and Audi AG in Germany had signed a strategic cooperation memorandum on thin-film solar cell technology, and the two sides would cooperate to carry out thin-film solar cell research and development projects. The specific cooperation contents include that the two sides plan to jointly launch the first Audi prototype vehicle with integrated film solar panoramic roof by the end of 2017, and the electricit

On September 14, Musk tweeted that Tesla Electric Truck Semi will be unveiled and tested in Hawthorne, California on October 26. Musk did not disclose the details. As far as the current news is concerned, it is reported that Semi has a range of 321-483 kilometers. Prior to this, Musk praised this electric truck endlessly: "like a sports car", "reduce freight costs", "add security". The upcoming Semi is going to subvert the freight industry. For example, in the United States, behind

After more than 10 years of efforts, the production and sales of electric vehicles in China exceeded 500000 in 2016, and the sales of electric vehicles in 2017 will exceed 700000-800000, which has a huge impact on the automobile industry. Made in China 2025 announced that it clearly supports the development of hydrogen powered vehicles. In October 2016, the Chinese Society of Automotive Engineering announced the technical roadmap for fuel powered lithium battery vehicles, including hydrogen powered vehicles. After

On January 6, the sixth Science and Technology Innovation Conference of Guoxuan Hi Tech Co., Ltd. was held in Hefei, Anhui Province. Li Zhen, chairman of Guoxuan Hi Tech, said in his speech at the conference that China's battery technology has made significant progress in recent years, and the energy density of lithium iron phosphate has increased from 100Wh/kg in 2007 to 145Wh/kg at present. Li Zhen shared three feelings at the meeting: First, some understanding of the policy. First, the issue of "more

According to foreign media reports, the scientific team of Central University of Florida (UCF) has developed a "super battery" that can store more energy. The performance of traditional lithium-ion batteries begins to decline to varying degrees after 1500 times of charging, while the performance of this supercapacitor will not decline after 30000 times of continuous use. "Just use this super capacitor to replace the battery in your mobile phone, and then charge your mobile phone for a few secon

The Watt Laboratory of Huawei Central Research Institute announced that it had achieved a major research breakthrough in the field of lithium ion batteries: it launched the first high-temperature long-life graphene based lithium ion battery in the industry. The experimental results show that the new high-temperature technology based on graphene can increase the upper limit service temperature of lithium ion batteries by 10 ℃, and the service life is twice that of ordinary lithium ion batteries. As early as tw

China's new energy vehicle industry has achieved rapid development under the promotion of various overlapping policies of the government. According to the data of China Automobile Association, in 2016, the sales volume of new energy vehicles in China reached 507000, with gratifying results. However, there are still many problems hidden behind the achievements: the core technology has not been broken through, the company pays more attention to scale than innovation, and relies on subsidies. On January 14, the Ch

Recently, Toyota announced that it will develop a new generation of electric vehicle batteries in the next few years, which is expected to increase the existing range and battery life by 15%. The battery life of new electric vehicles developed by Toyota has increased by 15% Hisao Yamashige, a Toyota battery technology researcher, said: "For electric vehicles, lithium-ion battery is a key technology. It is obviously necessary to improve this technology in the future to further improve its performance.&quo
