The energy density technology of lithium iron phosphate battery has been broken through. The poor energy density of lithium iron phosphate battery is a disadvantage known to the public. At present, the capacity density of lithium iron phosphate battery is generally about 150Wh/kg. Even if it is better, it is about 160Wh/kg. This is a big difference compared with the 200Wh/kg energy density of ternary battery. Breakthrough in energy density technology of lithium iron phosphate battery Now, some enterprises in

According to foreign media, researchers from the Department of Physics and Chemistry at Imperial College London have developed a new battery prototype using specially designed plastic film and simple salt water. The design principle of this new battery prototype (it can change the color when the battery is charged) can also be applied to the existing battery technology to create new devices for energy storage, biosensors and intelligent color changing materials.(Lithium - Ion Battery Equipment) At present, the m

With the promotion of policies and demands such as energy conservation and emission reduction, government subsidies, etc., China's automobile market is ushering in a "golden age" of new energy vehicle development. In recent years, traditional car manufacturers have begun to deploy electrification, and there are more and more Internet electric vehicle enterprises. The development trend of new energy vehicles is unstoppable. It is estimated that the production and sales of new energy vehicles in China w

In the future, the main part of passenger car charging will be slow charging. Only about 20% of the cases require fast charging, which is only for emergency use. Aiming at the problem of fast charging or slow charging of electric vehicles, Ouyang Minggao, an academician of the CAS Member, a professor of Tsinghua University, and director of the National Key Laboratory of Automotive Safety and Energy Conservation, pointed out the development direction of future electric vehicle charging mode at the Xumishan Confer

Component encapsulation may become an important source of technological innovation in the future. At present, the investment cost of 1GW component capacity is only 70 million yuan, which cannot be compared with the investment of hundreds of millions or even billions in silicon material, silicon chip and battery industries. Therefore, the module sector has always been considered as the lowest threshold among the four PV industry sectors. However, since the silicon chip and battery chip links have undergone maj

The emergence and development of battery management IC is closely related to various problems encountered in the use of lithium ion batteries. At the earliest time, a charge discharge protection chip for a single battery was designed to solve the overcharge and overcharge of lithium ion batteries. Later, a chip for multiple strings was developed in the series use of multiple lithium-ion batteries. At this time, it became a battery management chip. It is critical to collect the voltage data of each battery in the ba

Fuel power cell is a power generation device that directly changes the chemical energy of fuel into electrical energy. The principle of fuel power cell is an electrochemical device, and its composition is the same as that of ordinary batteries. The single cell is composed of positive and negative electrodes (the negative electrode is the fuel electrode and the positive electrode is the oxidant electrode) and electrolyte. The difference is that the active materials of ordinary batteries are stored in the battery, so

Recently, scientists from the Brookhaven National Laboratory of the Department of Energy (DOE) and the University of Arkansas developed an efficient catalyst for extracting electricity from ethanol, which is a liquid fuel easy to store and can be generated from renewable resources.(Lithium - Ion Battery Equipment) The catalyst described in the Journal of the American Chemical Society controls the electro oxidation of ethanol in an ideal chemical path, thereby releasing the full potential of stored energy of liqu

On October 28, the Ministry of Industry and Information Technology issued an announcement to publicly solicit opinions on the Specifications and Conditions for the Automotive Power Battery Industry, aiming to strengthen the supervision of automotive power battery products, prevent low-level repeated construction, and promote the technological progress and large-scale development of power battery manufacturers. According to the opinion draft issued by the Ministry of Industry and Information Technology, the tract
