With the continuous progress of science and technology, lithium batteries are widely used in mobile phones, laptops, electric vehicles and other electronic devices because of their high energy density, long life and portability. However, there are certain sa...

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

First, capacity test method 1. Constant current charge and discharge test: This is the most basic test method. Under the specified temperature environment (such as normal temperature 25℃), the lithium-ion battery is charged with a constant current until t...

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...

The following are the performance characteristics of high temperature lithium batteries and low temperature lithium batteries: First, high temperature lithium battery performance characteristics Second, low temperature lithium battery performance character...

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....

I. Definition Battery capacity: refers to the total amount of charge that a battery can hold, usually in ampere-hours (Ah) or milliampere-hours (mAh). It represents the capacity of the battery to store electrical energy inside and is an essential propert...

Lithium iron phosphate batteries have a long cycle life, which can generally reach more than 2000 times. This means that under normal conditions of use, after multiple charge and discharge cycles, the battery can still maintain a high capacity and performanc...

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....
