It is well known that the four important parts of lithium batteries are positive electrode material, negative electrode material, separator and electrolyte. However, in addition to the four important parts, the current collector used to store the positive and negative materials is also an important part of the lithium battery. Today we will talk about the positive and negative current collector materials of lithium batteries. 1. Basic information of collectors For lithium batteries, the commonly used positive

"The performance of the lithium battery developed by South Korea is excellent," said Major General Jung Il-sik, director of the "Next Generation Engineering" project of the Korea Acquisition Program Administration, in an interview with the "Defense News" website. According to the data released by the project, the new lithium battery is dedicated, and the time underwater can be doubled after replacing the lead-acid battery. According to information from the Hanwei Industry Agency, th

Global lithium battery production is expected to rise from 170GWh to 590GWh between August 2018 and 2021. As battery makers work to increase battery production and meet rapidly rising demand, automakers and investors are exploring next-generation battery technologies to enhance battery product performance or even replace existing ones. In this research report, we compare and analyze three important technical development directions of lithium batteries, discuss the advantages of the technology, application barriers

Lithium batteries have the advantages of high energy density, long cycle life and less environmental pollution, and have become the focus of research around the world, and have been widely used in computers, mobile phones and other portable electronic devices. However, with the rapid development of electric vehicles and advanced electronic devices, higher requirements have been placed on the energy density of lithium batteries. How to improve the energy density of lithium batteries, the key lies in the improvement

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

The Qinghai Salt Lake Institute of the Chinese Academy of Sciences disclosed on the 7th that the research team of the institute has made new progress in the research on the performance of salt lake nitric acid molten salt energy storage materials, which provides more possibilities for the application of salt lake nitric acid molten salt energy storage materials in solar thermal power generation. As an emerging energy technology, solar thermal power generation technology is an important technical field in my coun

According to foreign media "Arstechnica", physicist Gabriel Veith was inspired by a substance called oobleck to develop a new chemical formula to prevent lithium batteries from catching fire. Generally speaking, the two electrodes of a lithium battery are separated by a thin piece of plastic. When the thin plastic is squeezed and ruptured, the two electrodes come into contact, causing the battery to short-circuit and eventually cause an explosion. Although a non-flammable solid electrolyte could solve

A few days ago, Narada Power and Zhejiang University signed a strategic cooperation agreement in Hangzhou. The two parties will integrate the superior resources of lithium battery research and manufacturing, and work together to actively explore the field of all-solid-state lithium battery technology. According to the cooperation agreement, in the next four years, Narada Power and Zhejiang University will conduct research and development and application of key technologies for solid-state lithium battery product
