Industry Knowledge

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

Integrating nanotechnology into the lithium battery electrode material system to develop high energy density lithium battery materials for electric vehicles; the wear-resistant coating technology won the second prize of the National Science and Technology Progress Award; the development of environmentally friendly permanent polymer flame retardants... Reporter yesterday It was learned from Shandong University of Science and Technology that Shandong University of Science and Technology attaches great importance to t

A few days ago, Huizhou Yiwei Lithium Energy Co., Ltd. (referred to as Yiwei Lithium Energy) has a square aluminum shell ternary battery project with an annual output of 1.5GWh officially put into production in Jingmen, Hubei. Battery Co., Ltd. has an annual output of 150 million cylindrical lithium-manganese battery project production lines. According to the battery my country Network, the multi-faceted technical route layout strategy adopted by Yiwei Lithium Energy has formed a product pattern of power lithium ba

The current research hotspots of lithium batteries mainly focus on lithium-air batteries and lithium-sulfur batteries, both of which are considered to be the most promising new-generation lithium batteries. They are very different from previous lithium battery cathode materials in structure and reaction mechanism. 1. Lithium-air battery Lithium-air battery is a kind of metal-air battery, and its theoretical specific energy is very high due to the use of lithium metal with the lowest molecular weight as the ac

Today, I would like to briefly share with you what the specific requirements for the performance of the power lithium battery are and what kind of development and testing process should be followed. 1. Depot's demand for battery performance In fact, the basic requirements for batteries include: energy density (cruising range), safety, fast charging, cost, life, and size compatibility. 1. Energy density According to my country's automotive power lithium battery technology roadmap plan, by 2020, t

At the centralized charging station in Shenzhen, more and more electric vehicle drivers are using charging stack devices compatible with multiple power levels to charge their vehicles. In addition, with the continuous breakthrough of power lithium battery technology, the energy density and power density of lithium batteries have been improved in parallel, which on the one hand improves the driving range of electric vehicles, and on the other hand makes the replenishment time comparable to that of fuel vehicles. &qu

Although lithium batteries have become the mainstream of today's energy storage, the molecular and atomic basic science of their charge and discharge is still a mystery. According to the "NatureCatalysis" study by the U.S. Department of Energy's Argonne National Laboratory, the research team has made a breakthrough in obtaining the chemical composition of the solid-electrolyteinterphase (SEI) between the electrode and the liquid electrolyte. This will help improve the team's ability to pred
