On October 26, 2018, at the 2018 my country Distributed Energy Storage Summit at Beijing West International Trade Hotel, in the morning "Keynote Report" section, Professor Liao Qiangqiang from Shanghai Electric Power University brought us "Echelon Utilization of Batteries in Distribution Research and applications in energy storage systems" report. The following is the transcript of the speech: Ladies and gentlemen, good morning! My name is Liao Qiangqiang and I am from Shanghai Electric Po

At the 256th National Conference and Exposition (ACS) organized by the American Chemical Society (ACS) on August 22, researchers at Oak Ridge National Laboratory and the University of Rochester exhibited a new type of fire-resistant lithium battery, Its electrolyte can spontaneously change from liquid to solid when struck, preventing lithium batteries from catching fire when they rupture. Lithium batteries are generally composed of positive and negative electrodes and an electrolyte. Once a lithium battery place

"Recently, some soft-pack power lithium battery companies have begun to look for our company to develop a method of cooperating with the winding process." A senior executive of a winding equipment company revealed to Gaogong Lithium. Gaogong Lithium has learned that in the field of power lithium batteries, the manufacture of soft-pack lithium batteries is mainly based on the lamination process. However, due to the shortcomings of the lamination process in terms of efficiency and integrated automation,

According to media reports, TSLA (Tesla) has recently applied for a new patent to improve battery safety by isolating defective battery cells from negatively affecting functioning cells. The background of TSLA developing this patent is that since the battery cells will generate heat during the charging process and when releasing energy, TSLA found that the defective battery cells will generate heat, which will affect the function of the surrounding battery cells, and usually lead to the continuous battery life.

In recent years, with the country's strong support for new energy vehicles, the sales of clean and non-polluting electric vehicles have achieved a blowout rise. However, the current commercial lithium battery anode material graphite can only reach a capacity of 300~340mAh/g in practical applications, and it is difficult to improve, which is far from meeting the urgent needs of new market users for high-performance lithium batteries. Therefore, more and more people are devoted to developing battery materials

Since their introduction into the market in 1991, lithium-ion batteries have attracted much attention due to their high energy density and long lifespan. It has become an integral part of the energy economy in the 21st century. However, the application of lithium-ion batteries in large-scale battery fields such as automobiles and energy storage still has some safety issues that need to be solved urgently. The organic electrolytes of lithium-ion batteries are volatile, flammable and explosive. [1] The all-solid-stat

The working principle of the lithium-ion battery protection circuit is introduced With the development of the economy, electronic products have entered the homes of ordinary people. People's application demand for electronic products is also increasing. With the increasing application demand of electronic products, people's demand for lithium-ion batteries is also increasing. Lithium-ion batteries are batteries with relatively large power reserves and are widely used in various electronic products. Howev

Lithium Ion Battery The positive data of lithium-ion batteries are usually composed of the active compound of lithium, while the negative electrode is carbon with a special molecular structure. A common important component of the positive data is LiCoO2. During charging, the potential on the electrode causes the compound of the positive electrode to release lithium ions, and the molecules of the negative electrode intercalate into the carbon in a sheet-like structure. When the lithium ions are discharged, the li

A new study from the MIT Energy Initiative warns that the energy storage industry runs the risk of prematurely establishing a dominant technology that could abandon or miss out on a more suitable application of utility-scale energy storage. energy storage technology. "There's going to be some risk of technology lock-in," said William Bonvillian, one of the authors of the survey study and former director of MIT's Washington office, at a recent event sponsored by the Information Technology and In
