At present, the same concentration of lithium battery copper foil industry and battery industry is slowly increasing, and large and strong lithium battery companies have obvious development advantages. Recently, when accepting the investigation of investment institutions, Nord Co., Ltd. stated that it is difficult for small lithium battery copper foil companies to develop at present, and the development of new copper foil companies is also uncertain. There are two important reasons: First, the technology cannot

1. All-solid-state lithium battery The current commercial lithium battery electrolyte is liquid, so it is also called liquid lithium battery. In simple terms, an all-solid-state lithium battery means that all components in the battery structure exist in a solid state, replacing the liquid electrolyte and separator of traditional lithium batteries with solid-state electrolytes. Compared with liquid lithium batteries, all-solid-state electrolytes have the following advantages: high safety/excellent thermal stab

In recent years, with the rapid development of the electric vehicle industry at home and abroad, power lithium battery companies not only have to expand production scale to ensure production supply, but also face the "tough battle" to continuously improve key indicators such as product energy density. Recently, Ouyang Minggao, executive vice chairman of my country Electric Vehicle 100 Association and academician of the Chinese Academy of Sciences, responded to the above-mentioned key topics of concern

"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
