Lithium-ion battery manufacturers introduce the service life and technical status of lithium titanate batteries. Lithium titanate material is used as the negative electrode material of lithium-ion batteries. Since the industrialization of lithium-ion batteries in 1991, the negative electrode materials of batteries have been dominated by graphite. In recent years, with the development of new lithium-ion batteries, domestic and foreign researchers have conducted in-depth research on the characteristics of lithium tit

A brief analysis of the urgent need for lithium-ion battery manufacturers to master the core technology of power lithium-ion batteries. The perfection of my country's power lithium-ion battery industry is second to none in the world. Even if it occupies a place in the world in terms of new energy vehicle ownership and market, if it does not master the real core technology, my country's power lithium-ion battery industry will only be small. Strong, in order to prevent the development of power lithium-ion bat

The design of the battery thermal management system is the key to improving the life of lithium-ion batteries. Thermal management of lithium-ion battery systems is an indispensable link to ensure battery safety, extend battery service life, and improve battery system performance. With the leap-forward development of new energy vehicles in recent years, the capacity and size of lithium-ion battery cells have gradually increased, and high-power operating conditions have gradually increased, which has brought severe c

The length of battery life depends on two reasons. The first is that there are quality problems in itself, resulting in reduced performance and short usage; the second is that car owners usually do not know how to take care of the battery and wear out the battery. How should batteries be used to maximize their use and extend their lifespan? Kuai Kian Momentum has compiled 12 relevant experiences: 1. Resolutely do not use inferior chargers, and resolutely do not use chargers with mismatched models. The charger te

The so-called battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary. It uses a lead-based grid filled with sponge lead (also called a grid) as the negative electrode, a lead-based grid filled with lead dioxide as the positive electrode, and dilute sulfuric acid with a density of 1.26--1.33g/mlg/ml as the electrolyte. When the battery is discharging, metallic lead is the negative electrode and undergoes an oxidation reaction to produce lead sulfate; lead dioxi

In the field of lithium-ion batteries, due to the uncertainty of the impact of various parameters on battery performance, experimental design has a certain degree of blindness. The traditional exhaustive method to determine parameters has the disadvantages of heavy tasks, low efficiency, and is difficult to solve theoretical problems. With the development of simulation technology, simulation technology has been applied to the research and development of more and more scientific research fields. As a complementar

Battery balancing technology can improve the service life of the battery pack and extend the use time of the battery pack. It is suitable for large-capacity nickel metal hydride, 2V lead-acid batteries, lithium-ion batteries, 6V lead-acid, 12V lead-acid and other battery packs, as well as supercapacitor packs. Ladder batteries and selection Ladder batteries refer to batteries that have been used and have reached their original design life, and their capacity has been fully or partially restored through other

The quality indicators for evaluating switching power supplies should be based on safety and reliability as the first principles. Under the premise that the electrical technical indicators meet the requirements for normal use, in order to make the power supply operate safely and reliably in harsh environments and sudden failures, it is necessary to design a variety of protection circuits, such as soft start to prevent surges, prevent overvoltage, and undervoltage. voltage, overheating, overcurrent, short circuit, a

According to incomplete statistics from reporters, a total of 13 listed companies have invested a total of 43.5 billion in power batteries. Among them, BYD's 15 billion yuan investment in lithium battery expansion projects and the development of pure electric special vehicles is the largest, followed by Wulong Electric Vehicles' 9.3 billion investment in power battery projects. Jian Liang, an analyst at CCID Consulting's Automotive Industry Research Center, said in an interview with reporters that si
