The Energy research center of the Netherlands (ECN) has developed a new energy storage technology for lithium-ion batteries, which is said to increase the storage capacity of rechargeable batteries by 50%. In order to commercialize this new invention, ECN has also established a start-up company, Leyden JarTechnologies. This technology uses pure silicon anode to replace the graphite anode traditionally used in lithium-ion batteries, thus increasing the storage capacity of lithium-ion battery components by 10 t

Batteries are the hope of almost all new energy industries. All kinds of electronic equipment and electric vehicles need batteries. The technology and cost of batteries are the key to the marketization and popularization of these new energy products. Lithium ion batteries are the mainstream of battery technology now. However, many new companies are betting on the so-called next-generation new battery technology. However, whether it has commercial conditions or not has aroused experts' doubts about its prospects

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

According to different power sources, electric vehicles can generally be divided into hybrid vehicles, pure electric vehicles and fuel powered lithium battery vehicles. So who will become the future of electric vehicles? In a new study, researchers from the United States and Germany compared pure electric vehicles and hydrogen fuel powered lithium battery vehicles and found that, in terms of reducing carbon dioxide emissions, pure electric vehicles have more advantages than hydrogen fuel powered lithium battery

At the recently held Forum on Advanced Technology and Application of Power and Energy Storage Batteries, Chen Chunmei, Director of the Automotive Division of the Equipment Industry Department of the Ministry of Industry and Information Technology, revealed that the Ministry of Industry and Information Technology is currently accelerating the drafting and preparation of the Guiding Opinions on Promoting the Development of the Automotive Power Lithium Ion Battery Industry. The Opinions will make it clear that by 2025

At present, the structure of lithium ion battery is divided into positive stage, electrolyte and negative pole. There will be a layer of diaphragm between the electrolyte and the positive and negative electrodes. The root cause of Samsung's problem battery is this diaphragm. The unqualified diaphragm may cause direct contact between the positive and negative electrodes, which is equivalent to a short circuit, and then it may self ignite, and the serious point is explosion! In fact, the lithium-ion battery te

In the face of obstacles restricting the promotion of new energy vehicles, such as "cheat compensation" of car enterprises, unclear performance of power lithium-ion batteries and potential safety hazards, the subsidy orientation will give way to market innovation, which has become a consensus in the industry. The latest news shows that the Ministry of Science and Technology, the Ministry of Industry and Information Technology, the Ministry of Finance and the Ministry of Transport will work together to sol
