In the past 30 years, the cost of rechargeable lithium-ion batteries for mobile phones, laptops and automobiles has dropped significantly and become the main driving force for the rapid growth of these technologies. However, attempts to quantify the results of cost reduction are ambiguous and contradictory, which hinders attempts to predict the future of the technology or design useful policies and research priorities. Now, researchers at MIT have carried out a detailed analysis of the research on the price decl

On December 28, Dow announced that the company planned to invest in the construction of a full life cycle green manufacturing project of lithium-ion battery materials in Longnan Economic and Technological Development Zone. The project company was temporarily named Jiangxi Jiana Energy Technology Co., Ltd., with a registered capital of 200 million yuan. The main production and business scope was the positive material precursor of power batteries, cobalt salt products, nickel salt products, and recycling of waste lit

Recently, BYD second-hand batteries have become the "sweet cake" for the first time. According to foreign media reports, BYD has established a new cooperative relationship with Itochu. The latter will purchase second-hand power batteries recycled by BYD and convert them into large batteries. It will be sold to Europe, America, Africa and other regions in 2021. Like fuel vehicles, new energy vehicles also have their own service life, of which the most concerned is the treatment of old power batteries.

Which is more cost-effective, hydrogen fuel power generation facilities or lithium ion battery energy storage systems? I believe everyone has doubts about this question. According to a research conducted by MIT, hydrogen fuel power generation facilities will compete with lithium ion battery energy storage systems in seasonal energy storage applications, and their cost competitiveness will depend on the thermal efficiency of natural gas power plants they may replace. So, what is the status quo of global fuel cell

Spent lithium ion batteries contain precious metals, which are difficult to separate from each other for recycling. Spent batteries are a sustainable source of these metals, especially cobalt and nickel. However, the current methods used to separate them have environmental and efficiency deficiencies. A new technology uses electrochemistry to effectively separate and recover metals, making waste batteries a highly sustainable secondary source of cobalt and nickel. The reserves of cobalt and nickel are currently dec

Spanish researchers have developed an n-type crystalline silicon solar cell based on vanadium oxide thin films deposited by atomic layer deposition. The open circuit voltage of the battery is 631mV, and the short circuit current is 38.36mAcm- ²， The filling factor was 75.8%. In the researcher University ä t University Polit è cnica Catalonia (UPC) has vanadium oxide (V made crystalline silicon solar cell 2 ö 5) as hole selective film in Spain. The novelty of their method is to use atomic

As the source of lithium, phosphorus, nitrogen, potassium and other precious substances, water has become increasingly prominent. Lithium is particularly important because it is used to produce batteries. An international team of scientists, including scientists from the Wetsus Institute in Leeuwarden and the Wageningen University Research Institute (WUR), has been studying a technology that makes it possible to separate various substances from water.(Lithium - Ion Battery Equipment) The research team led by Lou

In the battery pack of electric vehicle (EV), the inconsistency of single battery will reduce the use level of battery pack and affect the performance of EV. Research on advanced battery balance control technology to reduce the differences in the use of single batteries will be able to maximize the efficiency of batteries, extend the service life, and increase the safety of EVs. The equilibrium theory and control technology studied by the author in this paper can not solve the performance difference caused by th

On January 17, it was reported that researchers from Ulsan National Institute of Science and Technology, South Korea, had recently announced that they had successfully developed a new type of "deformable polymer electrolyte lithium ion battery". This kind of battery is made of nano materials, which is safer and more reliable than the liquefied electrolyte of traditional lithium ion battery. Especially in the high-temperature environment, the performance of polymer electrolyte is more stable and control
