After switching from the 18650 type to the 21700 type, the capacity of a single lithium-ion battery with 1 battery increased by 35%. Take the 21700 battery produced by Tesla as an example. The capacity of a single battery can reach 34.8Ah, significantly increasing by 35%. Th...

Square lithium-ion batteries usually refer to aluminum or steel shell square batteries. The popularity of square batteries is high in China, because the structure of square batteries is relatively simple, unlike cylindrical batteries that use high-strength stainless steel as shells and accessories w...

1. Customization of battery volume, flexible size, and great flexibility, can achieve maximum or minimum requirements within the specified battery specifications by customers. 2. Customization of battery capacity, the capacity of lithium-ion batteries is related to the batte...

At present, the requirements for electric vehicles and energy storage applications include safety, high energy density, long lifespan, low cost, and the industrialization of products with mature technology to match the rapid development of these two industries. From now on, lithium-ion batteri...

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...
