Researchers from New York University, the State University of New York at Stony Brook and the University of Cambridge have developed an internal detection technology for lithium-ion batteries based on nuclear magnetic resonance imaging (MRI), which can provide diagnostic services for the internal operation of batteries and improve battery performance and safety. . Relevant research results were published in "Natural Materials Science". When the lithium-ion battery is charged, the lithium fiber will att

Silicon is mixed with various forms of carbon, including carbon fibers and graphite, which can provide a pathway for electrons to travel through the material, bridging the gaps created by silicon cracks. The battery pack costs more than $10,000, and that's the biggest reason that makes an electric car more expensive than a regular gas-powered car. Envia could solve some key problems and cut the cost of electric vehicle batteries in half. Source: MIT Tech Startups Envia, a startup with funding from General

As my country's oil price officially enters the era of 8 yuan, the voice of popularizing new energy vehicles is getting louder and louder. Faced with the people's high expectations, the government announced plans to actively carry out new energy vehicle demonstrations in the public service areas of large and medium-sized cities. energy supply. In terms of industry, many Chinese vehicle manufacturing companies have also begun to promote their electric vehicles, and new energy auto exhibitions and power lithi

The Dalian Institute of Chemical Physics of the Chinese Academy of Sciences (hereinafter referred to as "Dalian Institute of Chemical Physics") announced on the 11th that a research team led by researchers Li Xianfeng and Zhang Huamin has recently successfully developed a new generation of low-cost, high-power all-vanadium redox flow battery.  The inherent randomness, intermittency, volatility, and difficulty of direct grid connection of renewable energy such as wind energy and solar energy limit

With the development of the new energy industry, the use of power lithium-ion batteries is becoming more and more extensive, and the requirements for the casing of power lithium-ion batteries are also getting higher and higher. Today, the editor will talk to you about the processing process of the steel casing of power lithium-ion batteries? Details are as follows: What is the manufacturing process of the power lithium-ion battery steel case? When making battery steel shells, high-quality raw materials should

Structural principle of battery management system The battery management system is mainly composed of a charging module, a data acquisition module (including voltage, current, and temperature data acquisition), a balance module, a power calculation module, a data display module, and a storage communication module. It mainly manages and protects the use of the battery pack. Battery Management System Architecture The battery management system (bMS) involves microcomputer technology and detection technology,

What is the process technology of lithium battery diaphragm industry? Lithium-ion battery separators have complex processing techniques and high technical barriers. Lithium-ion battery separator is a critical inner layer component in a lithium-ion battery. Key properties such as battery capacity, cycle performance, and charge-discharge current density all have a direct relationship with the diaphragm, and the improvement of the performance of the diaphragm plays an important role in improving the overall performanc

What is a lithium-ion battery pack balance maintenance instrument? what is it used for? With the rapid expansion of the new energy vehicle market, the phenomenon of "squatting" in the use of urban electric buses has become prominent. This not only shortens the cruising range of new energy vehicles, but also affects the service life of electric vehicles due to the "premature aging" of battery life. Lithium-ion battery balance maintenance instrument is a portable product for dealing with outdated

The demand for lithium-ion battery management chips is strong, and the market is expected to continue to rise. With the acceleration of the popularization of mobile phone fast charging applications, the demand for accurate measurement of lithium-ion battery management chips has increased. A higher proportion of high-end mobile phones will use lithium-ion battery metering chips. In the past, some mobile phones used software to calculate battery capacity, which may not be able to meet the fast Comply with the specifi
