According to foreign media reports, researchers from the Karlsruhe Institute of Technology (KIT) in Germany and cooperative institutions have studied the structural changes during the synthesis of cathode materials for the development of future high-energy lithium batteries, and obtained information on the degradation mechanism of cathode materials. The important discovery of this may help to develop larger capacity batteries to increase the cruising range of electric vehicles. So far, electric vehicles have not

With the rapid development of the electric vehicle industry, lithium batteries are widely used in the field of power lithium batteries due to their high energy density, no memory effect and high safety. Due to the particularity of electric vehicles, higher requirements are also placed on the safety of power lithium batteries. For example, in the event of a safety accident such as a collision with an electric vehicle, the power lithium battery must not catch fire or explode to ensure the safety of drivers and passen

BYD's blade battery is the long cell method (importantly refers to the square aluminum shell), which is a method to further improve the battery pack by increasing the length of the cell (the maximum length is equal to the width of the battery pack) and making the cell flat and elongated. Technology for integrated efficiency. It is not a cell of a specific size, but a series of cells of different sizes that can be formed based on different needs. The specific shapes are as follows: The positive and negative e

What is the future development prospect of lithium titanate battery technology? What is the future prospect of lithium titanate battery technology? Lithium titanate battery technology is very advanced in the field of energy storage. It has the advantages of fast charging, long life, low temperature resistance, etc. It is especially suitable for fixed-line or fixed-line buses, Terminal trailers, etc. At present, lithium titanate batteries are not the mainstream battery technology. At present, domestic automakers

Design of Li-ion Battery Online Charge and Discharge Management Circuit 1Characteristics of lithium-ion batteries In recent years, the rapid development of portable electronics has led to an upgrade in battery technology. During this period, lithium-ion batteries continued to emerge and became the mainstream of the market due to their high energy density, high internal resistance, high battery voltage, high cycle times, and low self-discharge rate. According to statistics, in the field of notebook computers a

Recently, domestic power lithium battery companies have successively announced their 2021 annual financial reports. Although the fundamentals of the overall financial reports are gratifying, many companies have expressed that their concerns about future development remain unabated. Analyzing the financial reports, the situation of leading companies such as CATL, Yiwei Lithium Energy, Guoxuan Hi-Tech, and Funeng Technology is mixed. In 2021, the price of upstream raw materials will continue to soar, which will put s

At the "Nissan: Towards the Future" global press conference held at the end of November last year, Nissan announced its 2030 vision, planning to invest 2 trillion yen (total 100.88 billion yuan) in the next five years to accelerate the electrification and technology of its automotive product line Speed ​​of innovation, Nissan will launch 23 new electric vehicle models by fiscal 2030, aiming to achieve more than 50% electrification mix of Nissan and Infiniti brands globally. In addition to plans to brin

As an industry observer of the lithium battery industry for more than ten years, I have witnessed several ups and downs of the lithium battery industry, and also formed an industry analysis framework based on technology, output, supply chain, capital and competition pattern. Looking back on the first quarter of this year, the lithium battery industry was bustling with excitement, but it was basically in line with expectations. Since the end of last year, this official account has continued to emphasize the de

Scientists have been actively looking for new ways to shorten the charging time of electric vehicles. Recently, the team of Academician Yu Shuhong from the University of Science and Technology of my country, in cooperation with the team of Professors Yao Hongbin and Ni Yong, is committed to solving the contradiction between high energy density and fast charging performance of lithium batteries, and has proposed and prepared a new type of double gradient graphite anode material. The lithium battery charges to 60% in
