With the continuous development of lithium-ion battery technology, the pursuit of energy density is getting higher and higher. In the latest national guidelines for new energy vehicles, it is proposed that by 2020, the specific energy of a single power battery should reach 300Wh/ kg, it is very difficult to achieve this indicator on the existing lithium-ion battery system. At the just-held 3rd New Battery Positive and Negative Material Technology Estimation Forum, researcher Liu Jun from the Pacific Northwest Natio

When it comes to new energy vehicles, it is natural to talk about power lithium-ion batteries, and batteries are both familiar and unfamiliar to most of us. What is familiar is that batteries exist in all aspects of use around us, but what is unfamiliar is its ins and outs and temperament. The ternary lithium ion, which is widely used in new energy vehicles, is a constantly updated battery system, involving many research fields in physics and chemistry. This makes people lack in-depth and rational understanding of

Battery technology has always been the key to the next iteration of many consumer products. It directly pinches the pulse of the product in terms of battery life and portability. Any small step forward is a big step forward for consumer products. Of course, it is also extremely critical for automobiles. In the process of transforming to electrification, whether the power battery of new energy vehicles can be improved qualitatively will directly affect the pace of automobile development in the next decade. Previo

A few days ago, according to foreign media reports, "24M", a battery research and development company founded by Chinese scientist Dr. Jiang Yeming in 2010, received US$21.8 million (about 150 million yuan) in Series D financing. The company is currently committed to research and development and production of semi-solid lithium-ion batteries. A semi-solid battery refers to a battery in which either electrode does not contain a liquid electrolyte, and the other electrode contains a liquid electrolyte. O

Introduction: Scientists in the United States have used sophisticated imaging techniques to observe a previously unknown defect in the crystal structure of a solid electrolyte. These defects, the scientists reasoned, may play an important role in the electrolyte's performance, and more careful engineering of them into the material could yield impressive results. Although solid-state batteries have attracted the attention of the energy storage industry, their commercial applications to date have been very lim

In order to push the boundaries of battery design and accommodate more and more power and energy in a given space or weight, researchers are exploring a more promising technology that uses solid-state electrolyte materials between the two electrodes of lithium-ion batteries, while Not electrolyte. However, a problem with these batteries has always been that metal dendrites can form on one of the electrodes, eventually connecting the electrolyte and shorting out the battery. According to foreign media reports, re

Microsoft is considering integrating fuel-powered lithium batteries directly into racks to make data centers greener and more cost-effective. According to a new white paper from the company, the software giant wants to use biogas-based fuel-powered lithium batteries to improve energy efficiency, reduce overall operating costs, and improve reliability by dissipating risk. Microsoft has found that putting fuel-powered lithium batteries at the rack level will eliminate its reliance on basic electrical infrastructure s

Researchers at Delft University of Technology in the Netherlands and VU University Amsterdam have demonstrated that the size of metal alloy nanoparticles can change the rate at which hydrogen gas stored in metal hydrides is released. The smaller the nanoparticles, the faster hydrogen can get into the fuel-powered lithium battery. The researchers published their findings in the October issue of the scientific journal Advanced Energy Materials. On September 27, Dutch Environment Minister Melanie Schulz van Hage

Power batteries for unmanned ships are driven by environmental protection policies and economic benefits. Among nickel-hydrogen batteries, lithium polymer batteries and lithium iron phosphate batteries, it is more appropriate to use lithium iron phosphate batteries as power batteries for unmanned ships. Because lithium iron phosphate batteries are the best in terms of discharge performance and service life, of course they can also provide sufficient discharge rates and sufficient power.
