At low temperatures, the viscosity of the electrolyte of the polymer lithium battery will increase. It‘s like when a liquid gets thicker at low temperatures. The ionic conduction rate of the electrolyte slows down, making it difficult for ions to move arou...

Ex d IIC T3 Gb is a complete explosion-proof mark, Ex: indicates that the equipment is explosion-proof electrical equipment, is the abbreviation of English "explosion-proof", which is a sign that all explosion-proof equipment must carry....

Polymer lithium batteries are best not stored with metal items: Here‘s why: 1. Short circuit risk 2. Security risks

High nickel ternary lithium battery cathode material is usually composed of nickel, cobalt, manganese (or aluminum) three elements, of which the content of nickel is relatively high, generally refers to nickel content of 60% and above ternary cathode material...

Lithium battery dormancy is mainly due to a long time not used or excessive self-discharge of the battery, resulting in the battery voltage is too low and enter the hibernation state. This article teaches you several ways to activate....

In principle, lithium batteries in parallel is feasible. Parallel connection can increase the total capacity while keeping the voltage constant. When lithium batteries of different capacities are connected in parallel, their terminal voltages should ideally...

In order to calculate the voltage and capacity of lithium batteries, we must first understand the voltage of different cathode materials to calculate the rated voltage....

Due to the limitations of electrode materials, electrolytes, and battery structure and packaging, it is difficult for batteries to meet the requirements of high and low temperatures at the same time. In order to solve this problem, scientists are constantly ...

Battery ratio refers to the current value required when the battery releases its rated capacity within a specified period of time, which is an important indicator to measure the charge and discharge capacity of the battery....

Battery loss refers to the phenomenon that the actual capacity of the battery is reduced compared to the nominal capacity after a period of use....

In our daily life, whether in the industrial production environment or in the home environment, safety is an important factor that we must consider. Explosion-proof technology and intrinsic safety technology are two commonly used safety measures to protect e...

At present, there are often a large number of deceptive batteries on the market, sometimes involving well-known first-line brands. This kind of oil is cheap, dozens or even more than 100 yuan cheaper than the normal battery price per group, but this kind of ...

Hey, guys, you know what? In this era of electronic products, explosion-proof batteries are simply the "invisible guardians" of our safe use of various devices! Imagine, without them, mobile phones become hand grenades, drones become aerial bombs, that pict...

Battery explosion-proof certification ensures the safety of battery products, explosion and fire prevention, which is related to consumer safety and enterprise competitiveness. It is tested by third party, complies with IEC, UL and other standards, and ...

Fast charging lithium batteries generate more heat during the fast charging process, which requires higher requirements for thermal management systems. If the thermal management is not good, it can easily lead to local overheating and increase safety risks. ...
