Lithium batteries mainly consist of four parts: positive electrode, negative electrode, non-aqueous electrolyte and separator. Currently, the most commonly used lithium batteries on the market are lithium iron phosphate batteries and ternary lithium batteries. The cathode raw materials of the two are quite different, and the production process is relatively similar, but the process parameters need to change greatly. If lithium iron phosphate is completely replaced with ternary materials, the rectification effect of

Will quaternary lithium-ion battery technology be the future development direction of power lithium batteries? Driven by the current new energy industry, the power lithium battery industry is developing rapidly. Facing the huge market gap, upstream manufacturers are also rising. In the stack era, cobalt-free material and quaternary material batteries are the "vanguard" in the development of power lithium batteries, and it has officially launched the cobalt-free material and quaternary material batteries d

Lithium-ion battery management systems and cells are very critical technologies for OEMs. At this stage, both vehicle manufacturers, battery factories, and related vehicle electrical components factories are investing in the research and development of lithium-ion battery management systems in order to master the key technologies of the lithium-ion battery industry for electric vehicles; and whether it is lightweight vehicle bodies, fast charging , or high and low temperature testing, etc., it all ultimately comes

The lithium iron phosphate battery BMS management system is highly consistent with the development of 5G base stations. The demand for energy storage in 5G base stations has increased significantly, and the counterattack of lithium iron phosphate batteries seems to be gradually beginning. A BMS lithium-ion battery management system will transform a group of "dumb" cells into a smart lithium-ion battery pack. Phosphate The application demand of iron lithium-ion batteries in base stations has "skyrocke

Recently, researchers from Hyundai Motor Company found that sulfone-based electrolytes can effectively improve the capacity and reversible capacity retention rate of lithium-sulfur batteries. At the 2014 Society of Automotive Engineers World Congress, Hyundai Motor Company reported in detail the above new findings. Compared with ordinary electrolytes, the capacity of lithium-sulfur batteries can be effectively increased by using sulfone-based electrolytes, with the capacity increased by 52.1% to 715 mAh. hour/g; th

Lithium batteries are currently one of the most widely used batteries. Their high energy density, long life, and portability make them the main power source for electronic products such as mobile phones, tablets, and electric vehicles. However, lithium batteries also have some safety hazards during use, one of which is waterproofing. This article will discuss the necessity of waterproofing lithium batteries, waterproofing measures, and precautions after waterproofing.   1. The necessity of waterproofing lith

Protection level, what we often call IP level, dustproof and waterproof performance, is to avoid dust and water from affecting the insulation performance of the cells, electrical components, control system circuit boards, etc. inside the battery pack, and from corroding metal devices; If the protection level of the lithium battery shell does not meet the dustproof and waterproof requirements, the environmental conditions of the battery cells and electrical components will be uncontrollable. In a general working

Britain wants to secure a place at the forefront of the electric vehicle revolution and, to that end, recently approved the construction of a battery research center. The UK Battery Industrialization Center (UKBIC), which will lead cutting-edge research into battery manufacturing technology, has received planning permission in Coventry. Last year, British Business Secretary Greg Clark announced that the government would allocate 80 million pounds to support the construction of the center, which is located in the

Experts said that the formulation of safety standards should be actively promoted and vigorously implemented. Products that cannot pass safety standards must be strictly prohibited from being launched. This is one of the ways to solve the safety problems of lithium-ion batteries and reduce the occurrence of accidents. With the rapid improvement of lithium-ion battery technology, its application fields are becoming wider and wider. While consumers enjoy the convenience that lithium-ion batteries bring to life, th
