GlobalGeoscience, which explores and develops lithium ore in Riolette, Nevada, USA, strives to become the world's first company to produce lithium ore by tank leaching. The first stage of Rhyolite Ridge project is feasible Sexual research has been completed, pointing to low-cost, high-volume production methods for lithium boron. The company demonstrated different production methods, including tank leaching, heap leaching and agitated tank leaching, and finally chose to conduct tank leaching around the acid p

As a new type of electrochemical energy storage technology, flow battery is one of the preferred technologies for large-scale energy storage of clean energy. Recently, the Dalian Institute of Chemical Physics, Chinese Academy of Sciences has developed a new type of long-life, self-recoverable zinc-iodine flow battery, which effectively solves the problems of short cycle life, low power density, and discontinuous power generation such as wind and solar power. Stability, uncontrollable and other problems have realize

Throughout the current new energy vehicle market, there are many types, but the key core component is the energy storage equipment of the vehicle. The battery energy storage capacity is the biggest bottleneck in current research: on the positive electrode, the energy storage capacity of sulfur is larger; on the negative electrode, the energy storage capacity of silicon and metal lithium is larger, this problem needs to be determined by the selection of electrode materials. to solve. Therefore, it is necessary to tr

Fisker lost the first time on lack of core technology, what about the second time? At this year's CES, American luxury electric company Fisker exhibited its latest pure electric vehicle - Fisker EMotion. Does it sound a little familiar? However, this is not the Fisker acquired by Wanxiang Group. Henrik Fisker, a car designer, has experienced the bankruptcy of his own brand, the failure of the first model, the Fisker Karma, and the relationship with Tesla. Now, he has re-founded a new company in his own

But what the author wants to emphasize is that the achievements of these forward-looking technologies still have a considerable distance from industrialization. Of course, this does not mean that the research of domestic experts is out of industrialization, but that the lithium battery itself is still far from the next-generation battery technology. The current domestic consensus is that in the near future, 300wh/kg will be achieved through high nickel ternary cathode and silicon carbon anode; It is to develop l

Oil giant BP said recently that its venture capital fund has invested $20 million in Israeli company StoreDot. StoreDot has developed a battery system that can charge an electric car in the same amount of time it takes to fill a gas tank. BP Ventures said the investment is part of a push to develop electric vehicle technology and infrastructure. Tufan Erginbilgic, CEO of BP Downstream, said: "Ultra-fast charging is at the heart of the company's electrification strategy. We are committed to being the

In the new energy vehicle industry, technical problems such as difficult charging and long charging time have always been one of the obstacles to the promotion of electric vehicles. In the case that the charging facilities cannot fully meet the demand, the core problem of all this is that the charging technology of electric vehicles is not up to standard and cannot meet the requirements of fast charging. Power vehicles that can meet fast charging have become a dominant demand in the industry.（Lithium - Ion Battery

Last year, the global release of the timetable for the ban on the sale of fuel vehicles made people realize that the era of new energy vehicles is coming, and why pure electric vehicles, plug-in hybrids, fuel cell vehicles, etc. have become the future in just a few years the main theme? On the one hand, it is the support of global strategies, policies, etc., on the other hand, the continuous improvement of power battery technology, longer battery life and shorter charging time, which are directly related to the com

Inspired by the biological spine structure, GuoyuQian et al. of Columbia University developed a flexible lithium-ion battery that maintains the advantage of high volumetric energy density while ensuring good flexibility. The basic structure of a flexible battery can be divided into a backbone and branches connected to the backbone. These branches are wound around the backbone to form a structure similar to an animal's vertebrae, and the backbone is connected to the external circuit. This structure not only e
