In 2018, Guoxuan Hi-Tech invested 493 million yuan in research and development. The research and development projects include: 22-platform lithium iron phosphate battery development, ternary battery development and industrialization, battery capacity design and manufacturing assurance technology, model-based battery design and There are 6 major projects including intelligent manufacturing technology development, technology to improve battery energy density, and 20 platform lithium iron phosphate battery development

Is hydrogen fuel-powered lithium battery a real black technology? Recently, BYD revealed to investors that it is developing hydrogen fuel-powered lithium batteries. In fact, in May, BYD struck a deal with an American company, Hybrid Electric Power, to collaborate on hydrogen fuel-powered lithium-ion battery buses. Not only BYD, it is understood that domestic companies Weichai Power and Great Wall Motors have successively deployed hydrogen fuel-powered lithium batteries. Japan's Toyota began research on hy

In recent years, the development of new energy vehicles has developed by leaps and bounds, and there is a tendency for latecomers to catch up. In the research and development process of new energy vehicles, whether it is the extended-range hybrid model Volt launched as early as 2010, or planned in 2023 Before the vision of launching at least 20 pure electric vehicles, GM has already placed new energy vehicles at the height of corporate strategic development. Whether it is a pure electric vehicle or a hybrid vehi

1. Electromotive force The electromotive force is the difference between the balance electrode potentials of the two electrodes. Taking lead-acid batteries as an example, E=Ф+0-Ф-0+RT/F*In(αH2SO4/αH2O). Among them: E—electromotive force Ф+0—positive standard electrode potential, its value is 1.690 Ф-0—negative standard electrode potential, its value is -0.356 R - universal gas constant, its value is 8.314 T - temperature, related to the temperature of the battery F

A subsidiary of LG Group is investing heavily in a U.S. R&D subsidiary to develop the fuel cell business, developing "solid oxide fuel cells," which LG says are third-generation fuel cells. It looks like LG Group is poised to continue pouring R&D dollars into new fuel cells, which it did last year and continue this year. Industry insiders pointed out on the 20th that LG Group subsidiaries LG Electronics, LG Chem, and LGCNS recently invested $38.4 million in LGPureCellSystems, a subsidiary of LG

The development of high-performance power batteries is one of the important measures to promote electric vehicles. Recently, the reporter learned from the second quarter regular press conference of the Chinese Academy of Sciences that the energy density of a variety of power battery cells developed by the Chinese Academy of Sciences has reached more than 300Wh/kg, ranking the world's advanced level; my country's power lithium batteries have entered the core technology. In the stage of large-scale applicatio

1. Lithium batteries are usually divided into two categories according to internal materials: Lithium metal battery: Lithium metal battery generally uses manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and uses a non-aqueous electrolyte solution. Lithium-ion batteries: Lithium-ion batteries generally use lithium alloy metal oxides as positive electrode materials, graphite as negative electrode materials, and use non-aqueous electrol

As fuel cell electric passenger vehicles enter the market, many consumers believe that fuel cells are only used in cars. In fact, fuel cell electric passenger vehicles are probably one of the toughest markets to break right now, and fuel cells can scale to meet many different energy conversion or power needs. Fuel cells are proving to be a versatile technology from primary stationary power and cogeneration applications, to powering cell phones and laptops.(Lithium - Ion Battery Equipment) There are already three

Recently, researchers at Linköping University in Sweden have successfully developed a new type of fuel cell using lignin from trees as a raw material. Unlike batteries that use small molecules such as methanol and ethanol as fuel, this process does not generate carbon dioxide, not only is the raw material green and environmentally friendly, but also the product achieves zero carbon emissions. Lignin is an important structural material for plants and algae. It is common in bark or wood and is one of the by-p
