1. The energy is relatively high. It has a high storage energy density, currently reaching 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries; 2. Long service life, with a service life of over 6 years. A battery with lithium ferrous phosphate as the positive...

When it comes to power lithium batteries, they are actually very important in terms of technology. Power lithium batteries pursue five aspects of performance, with safety being the top priority. The other two pursuits are energy density, power density, and most importantly, service life. The last on...

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

There are also some issues with the use of batteries, as external or internal short circuits can result in 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 inter...

Mobile phone batteries frequently experience explosions, partly due to the failure of protective circuits, but more importantly, the problem has not been fundamentally solved in terms of materials. Lithium cobalt oxide positive electrode active material is a mature system in...

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

Compared to lead-acid batteries, lithium-ion batteries 1. In terms of safety, lead-acid batteries are safer to use. Lead acid batteries are resistant to overcharging, so they can be used directly. Lithium ion batteries require protective plates to ensure that the battery bod...

Types of separators for lithium-ion batteries The separators of lithium-ion batteries can be classified into different types based on their structure and composition. Currently, there are three common and important types in the market, namely porous polymer membranes, non-wo...

What is the separator for lithium-ion batteries? In the structure of lithium-ion batteries, the separator is one of the key inner components. The performance of the separator determines the interface structure, internal resistance, and other characteristics of lithium-ion ba...

9. The incoming shell material has a thicker shell wall, and the deformation of the shell affects the thickness; 10. The high temperature outside is also an important cause of explosions. Protective measures taken by batteries After overch...
