As is well known, new market demand for lithium-ion batteries is rapidly forming. Lithium ion batteries are currently divided into three major sections. The first one is consumer electronics products. Nowadays, the vast majority of mobile devices, smartphones, and laptops already use lithium-i...

There are also some issues with the use of batteries, as external or internal short circuits can cause excessive currents of several hundred amperes. When there is an external short circuit, the battery instantly discharges with high current, consuming a large amount of energy on the internal...

The frequent explosion incidents of mobile phone batteries are partly due to the failure of protective circuits, but more importantly, there is no fundamental solution to the problem in terms of materials. Lithium cobalt ion positive electrode active material is a mature sys...

4. Sealing performance: The batteries of pure electric vehicles are generally placed at the chassis, and the sealing performance of lithium-ion batteries is better. In normal wading or potholed roads, the impact resistance and waterproof ability of batteries directly affect the safety level of...

Compared with Lead–acid battery, lithium-ion battery 1. In terms of use safety, Lead–acid battery will be safer. Lead–acid battery are resistant to overcharge, so Lead–acid battery can be used directly. Lithium ion batteries need protection plates to ensure that the main...

The so-called over discharge refers to the situation where the battery continues to discharge after discharging the internal stored electricity and the voltage drops to a certain value, resulting in over discharge. Generally, the discharge cutoff voltage is determined according to the discharg...

The so-called overcharging, as the name suggests, refers to overcharging the battery, which means continuing to charge it after it is fully charged. After being fully charged, continuing to charge to a certain level can cause the gas generated by the decomposition of the ele...

Wu Wencheng, an analyst at Dongwu Securities, announced in a research report on July 28th that this round of downstream expansion has benefited all first and second tier equipment companies. Compared to leading companies, second tier brands benefit from order overflow and ha...

The R&D projects in this fundraising investment project will also purchase corresponding R&D equipment and software systems, carry out research and development, structural design and intelligent manufacturing of key material systems of new generation power and energy storage batteries,...

According to the Science and Technology Innovation Board Daily (Shanghai, researcher Song Ziqiao), after the 12th trading day, CATL disclosed a large fixed increase method, with a total planned fundraising amount of no more than 58.2 billion yuan. After deducting issuance fees, it plans to use...
