Integrate nanotechnology into the lithium battery electrode material system to develop high-energy-density lithium battery materials for electric vehicles; the abrasion-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

In recent days, there has been a lot of discussion about the first half data of new energy vehicles. According to news released by the Ministry of Industry and Information Technology, my country's new energy vehicle production increased significantly in the first half of the year. Looking at such bright data, many people will feel more confident. But in fact, the development of new energy vehicles is still full of hidden dangers, and batteries are one of the most important factors limiting development. Recen

Recently, the South Korean industry has expressed concerns about the development of new energy vehicles and lithium batteries in China: the rapid development of Chinese latecomers threatens South Korea's major export industries such as automobiles, IT, electronics, petrochemicals and steel. In the future of emerging industries, China will be a huge threat. Among them, not only China's GCL and other solar companies are growing rapidly, but the battery industry is also developing rapidly. According to mark

Recently, Category 4 Hurricane Harvey swept across the southern Texas coast of the United States, causing power outages to 300,000 households. However, the magnesium battery developed by Yao Yanxin, a professor at the Department of Electrical Engineering at the University of Houston and the Texas Superconducting Center, brings hope to people in dealing with disaster power outages. The team's new magnesium battery makes cheap and safe energy storage technology possible. In an interview with Science and Techno

The development of energy storage technology is the key to ensuring the large-scale development of clean energy and the safe and economic operation of the power grid. Energy storage technology can add electric energy storage links to the power system, making the "rigid" power system with real-time power balance more "flexible". In particular, it can suppress the volatility caused by the connection of large-scale clean energy power generation to the power grid and improve the operation of the pow

What is the process of soft pack batteries? 1. Soft-packed batteries To put it bluntly, soft-packed batteries are batteries that use aluminum-plastic film as packaging material. The main packaging used is rheumatic heat packaging. The reason why laser welding is not used is that the packaging material of aluminum plastic film is easier to package and form than the outer packaging of steel shell or aluminum shell. 2. Aluminum plastic packaging film Aluminum-plastic packaging film is actually aluminum-plastic

Lithium-ion battery process defects 1. Poor packaging The proportion of bloated battery cells caused by poor packaging has been greatly reduced. We have already introduced the causes of poor packaging on the three sides of Topsealing, Sidesealing and Degassing. Poor packaging on any side will lead to battery cells. Most of them are Topsealing and Degassing. Topsealing is mainly due to poor sealing of the Tab position. Degassing is mainly due to delamination (including electrolysis). The influence of liquid an

When a lithium-ion battery is charged, the lithium atoms in the positive electrode lose electrons and are oxidized into lithium ions. Lithium ions swim to the negative electrode through the electrolyte, enter the storage compartment of the negative electrode, obtain an electron, and are reduced to lithium atoms. When discharging, the entire process is reversed. In order to prevent the positive and negative electrodes of the battery from directly touching each other and causing a short circuit, a separator paper wit

Lithium-ion battery separator pore size and lithium-ion battery separator process. The separator is an important part of the lithium-ion battery. Its important purpose is to separate the positive and negative electrodes of the battery to prevent the two electrodes from contacting and causing a short circuit. In addition, it also has the function of allowing electrolyte ions to pass through. The lithium-ion battery separator itself has a microporous structure, and the uniformity of pore size and distribution directl
