In April last year, Lisa Smith, the author of this article, took a look at the latest lithium battery research results published in the "Advanced" magazine family. More than a year later, it looks like current research into battery technology will continue to expand, with many potential alternatives to lithium systems being actively sought. Now seems like a good time to share an update on our work on these new systems. But first, we need to take a quick look at the motivations behind this massive internat

Industry insiders say, "Finding an electrolyte with a suitable ratio is a bit like taking traditional Chinese medicine. It's like taking different prescriptions for different physiques and illnesses. The formula of the electrolyte needs to be determined based on the type of positive and negative electrode materials, battery shape, and battery performance of the lithium battery." [Performance] The volume and price of electrolyte solvent products rose sharply. Shi Dashenghua’s net profit in the

The Beijing Graphene Industry Innovation Center’s technological achievements conference was held grandly during the 20th Beijing Science and Technology Expo. At the meeting, Beijing Graphene Technology Research Institute released the results on behalf of the Beijing Graphene Industry Innovation Center, and also released the Beijing Graphene Industry Innovation Center’s “four-axis linkage” industrial development roadmap. Beijing attaches great importance to the work of the Graphene Industr

At present, the market demand for new energy vehicles in my country is driven by government subsidy policies, rather than real rigid demand. Wang Zidong said that the large companies that are growing now were cultivated under such severe bubble conditions, and in fact they may not be truly strong. Judging from the financial reports of major listed companies, most of the financial data are not optimistic. From the perspective of the global market, my country's new energy passenger vehicles' world share reach

South Korea's new energy vehicles and power lithium-ion battery industries started early and are concentrated in scale. The government attaches great importance to the development of core component systems and has promoted the development of electric vehicles (EV, PHEV), hybrid electric vehicles (HEV) and hydrogen energy since 2014. A green and environmentally friendly vehicle plan with FCV as the core. As of 2018, a total of nearly 290,000 environmentally friendly vehicles have been produced. The government ha

Batteries play an important role in modern life, powering laptops, phones, robot vacuum cleaners, hearing aids, pacemakers, and even electric cars. But at the same time, it also presents safety risks and impacts on the environment. Texas A&M University (Texas A&M University) conducted research on the composition of a special battery-metal-free water-based battery. The battery reduces the flammability of standard batteries and uses fewer metals in the battery production process. (: Journal CellReportsPhys

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
