According to foreign media reports, Faurecia participated in the Hannover Messe in Germany for the first time this year. The company will display fuel cell solutions at the exhibition to support the transformation of the automotive industry to zero-emission mobility solutions. Faurecia aims to optimize high-pressure fuel tanks to advance fuel cell technology and stacks for industrialization in the automotive industry. Faurecia devotes considerable technical experience to its system integration, integrating hydro

As an extremely important non-metallic mineral, its processed products are not only widely used in traditional industries such as iron and steel industry, but also in emerging industries such as new energy and new materials, and are considered to be an important strategic resource to support the future development of high-tech . The Chinese government attaches great importance to the protection, development and utilization of graphite resources. In November 2016, the National Mineral Resources Plan (2016-2020) appr

The decline of subsidies has forced the battery industry to concentrate, and the power battery will usher in a knockout game in the second half. Technological upgrades have intensified global competition, and improving energy density has become the way to advance. On January 16, a seminar on the development direction of power batteries under the new situation in 2018 was held in Nanjing. Liu Yanlong, secretary-general of China Chemical and Physical Power Industry Association, attended the meeting and pointed out

Improving the energy density of batteries (limited to capacity batteries) is the first priority in designing batteries. If the capacity is not enough, no matter how low the unit price is, how good the cycle is, and how high the safety is, the battery that is made may not be interested. So how can we improve the energy density of the battery? It can be considered from several aspects:(Lithium - Ion Battery Equipment) 1. Increase the performance of materials that contribute to battery capacity; 2. Reduce the

In recent years, benefiting from the rapid growth of China's demand for new energy (electric) vehicles and energy storage, my country's lithium battery industry, especially the power lithium battery industry, has ushered in an explosive period of development, and the industry's long-term prospects are optimistic by all parties. Therefore, many listed companies have deployed lithium batteries in an attempt to grab a share. For a time, lithium battery concept stocks have emerged one after another, and it

According to foreign media reports, scientists are currently studying the conversion of mechanical, thermal, and chemical energy in the human body into electrical energy through piezoelectric effects, thermal energy conversion, electrostatic effects, and chemical reactions, so as to provide wearable or implantable devices. powered by. In ISing the Body Electric, poet Walt Whitman speaks fondly of the "action and power" of "beautiful, strange, breathing, laughing muscles." More than 150 years

The occurrence of binder floating is mainly due to drying conditions. The drying conditions mainly include drying method (electric heating, infrared heating or steam heating), drying temperature (temperature selection), oven setting (several sections of oven), temperature gradient, etc. Liu Ping of China Electronics Technology Group Co., Ltd. studied the drying method of a certain cathode slurry. The effect of drying temperature and oven setting on the peel strength of the pole piece is shown in the figure:(Lith

On April 21, the "2018 my country New Energy Power Lithium Battery and Energy Storage Industry Conference" was held in Taizhou, Jiangsu. In the sub-forum with the theme of "opportunity, innovation and breakthrough", many power lithium battery experts, scholars and representatives of power lithium battery companies talked about the opportunities and challenges currently faced by the power lithium battery industry at the meeting. Ye Shengji, Deputy Secretary-General of the my country Associatio

Unlike traditional batteries that supply electrical energy in the form of energy storage, hydrogen fuel power cells convert chemical energy into electrical energy through the electrochemical reaction between hydrogen and oxygen. As long as there are sufficient hydrogen and oxygen sources (air sources), this conversion The process can go on forever and achieve zero pollution discharge. It is a new type of power generation technology that is efficient, safe, clean and flexible. At present, hydrogen fuel power cells a
