Supercapacitors are mainly composed of electrodes, current collectors, electrolytes and separators, among which electrode materials are the most critical factor affecting the performance and production cost of supercapacitors. Research and development of high-performance, low-cost electrode materials is an important part of the research and development of supercapacitors. At present, the most researched supercapacitor electrode materials are mainly carbon materials, metal oxides (or hydroxides), conductive polymers

South Korea's lithium-ion battery has a good market prospect in my country. It is only a matter of time before entering the "catalog" and getting "subsidy". Now with the arrival of "Sade", Korean lithium-ion batteries have been marginalized in the Chinese market. "Some Koreans once said that the Dragon Boat Festival originated in South Korea, and the Koreans wanted to apply the Dragon Boat Festival to the World Heritage List. Later, the Koreans said that Confucius was Korea

On September 1, the listing application of Qingdao Zhongke Hualian New Materials Co., Ltd. (stock abbreviation: Zhongke Hualian Securities Code: 838867) was approved and successfully listed. Zhi Lipeng, chairman of Zhongke Hualian, said: "After landing on the New Third Board, the company will be more standardized in management and systems, more transparent in operation, and more influential in the market." Zhongke Hualian was established in 2011 and is currently the only company in China that can su

When designing an automatic production line for a customer, it is necessary to provide clear information to the supplier. With these standards, the design can be more convenient, the compatibility is maximized, and it is also convenient for future acceptance. With the continuous popularity of the new energy industry and the gradual clarification of various standards, the demand for power lithium battery modules and pACK automatic assembly lines is also increasing. Especially since the second half of 2015, many d

With the rapid development of electric vehicles, how to solve the safety problems brought by electric vehicles has become a new topic and difficulty in the automotive industry. As the power source (or one of the power sources) of electric vehicles, the power lithium battery system has become the focus of public attention for its safety and reliability. Studying the failure mode of the power lithium battery system is of great significance to improve the battery life, the safety and reliability of electric vehi

The direct consequence of the surge in investment is the "Great Leap Forward" in the production of power lithium batteries in 2016. The balance between the supply and demand of lithium-ion power lithium batteries will be broken, and the industry is facing a key turning point. In 2016, the production and sales of new energy vehicles in my country continued to increase rapidly. Electric vehicles from January to March [: Unless otherwise specified, the electric vehicles mentioned in this article include p

The performance of traditional anode materials has reached the limit, and the demand for anode materials in the traditional energy storage field has also been saturated, and the layout of the power lithium battery market has become a "must fight" for anode material companies. The four important components of lithium-ion batteries include positive electrode, negative electrode, electrolyte and separator. Among these four materials, the price of negative electrode material is relatively stable, and the t

On September 6, at the "Power Storage Battery Frontier Technology and Application" forum hosted by the Battery Industry Alliance, the reporter learned from Chen Chunmei, Director of the Automobile Division of the Equipment Industry Department of the Ministry of Industry and Information Technology that the Ministry of Industry and Information Technology is currently accelerating the drafting and compilation of "Promoting Automotive Power". The Guiding Opinions on the Development of the Lithium Ba

This paper introduces the characteristics of lithium-ion batteries, summarizes the development history of electric vehicle battery management systems, briefly introduces the requirements, functions, and technical characteristics of battery management systems, and makes an outlook for the development of electric vehicle battery management systems. The emergence of electric vehicles is driven by global warming, environmental pollution and energy crisis. In 2015, the global production and shipment of electric vehic
