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 improvement of energy density and lightweight of lithium batteries are the keys to future demand expansion. Especially in recent years, the market for "gadgets" for ordinary consumers that can perform multitasking has expanded, which has increased the demand for lithium batteries with high energy density and small weight. Industry analysts point out that in addition to traditional main applications such as laptops and mobile phones, new applications such as electric hardware tools, other consumer e

The Power Lithium Battery Engineering Laboratory of Ningbo Institute of Materials has carried out research on aluminum-ion batteries using graphene as electrodes. The recent research work was published online in "Advanced Energy Materials" under the title Large-sized few-layer graphene enable sa ultrafast and long-life aluminum-ion battery. Electrochemical energy storage technology is the key to solving the problem of integrating electric vehicles and renewable energy into the grid for power generation

The development of the new energy vehicle industry will bring positive impetus to the power battery market. Power batteries are still an emerging industry, and the high cost of battery systems is the main reason for the high price of electric vehicles. In hybrid vehicles, pure electric vehicles, and plug-in hybrid vehicles, the electric drive system is the main part of the value of new energy vehicles, and its value is more than half of the total vehicle cost; while the cost of the power battery in the electric dri

Reporter yesterday It was learned from Shandong University of Science and Technology that Shandong University of Science and Technology attaches great importance to

In recent days, there has been a lot of discussion about the first half data of new energy vehicles. According to news released by the Ministry of Industry and Information Technology, my country's new energy vehicle production increased significantly in the first half of the year. Looking at such bright data, many people will feel more confident. But in fact, the development of new energy vehicles is still full of hidden dangers, and batteries are one of the most important factors limiting development. Recen

Recently, the South Korean industry has expressed concerns about the development of new energy vehicles and lithium batteries in China: the rapid development of Chinese latecomers threatens South Korea's major export industries such as automobiles, IT, electronics, petrochemicals and steel. In the future of emerging industries, China will be a huge threat. Among them, not only China's GCL and other solar companies are growing rapidly, but the battery industry is also developing rapidly. According to mark

For consumer batteries, because the power consumption of electrical devices is relatively small, the power output of a single battery core can basically meet the requirements, so several batteries are rarely used together. The power of a single battery cell is small. When encountering applications with high power output, such as electric vehicles and energy storage, it is necessary to connect many cells in series and parallel to obtain relatively high output voltage/output power/output current/output power, etc. .

Power lithium batteries for new energy vehicles can be divided into secondary batteries (including lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries) and fuel power batteries. We will refine it, starting from the classification of lithium-ion batteries, and analyze the mainstream technical routes of power lithium batteries currently on the market. working principle First of all, correct a concept. Lithium-ion batteries are usually divided into two cate
