Research on Safety problems and Solutions of Lithium Battery
Apr , 24 2023
I. the danger of lithium-ion batteries. Lithium-ion battery is a potentially dangerous chemical power source because of its own chemical characteristics and system composition. (1) high chemical activity. Lithium is the main group element of the second cycle of the periodic table, which has extremely active chemical properties. (2) High energy density. The specific energy of lithium-ion battery is...

Damage of lithium battery caused by overcharge and discharge
Apr , 24 2023
The cathode materials of lithium-ion batteries are usually composed of active compounds of lithium, while the negative electrodes are carbon with special molecular structure. The main components of the common cathode materials are licoo2/LiFePO4, etc. When charging, the potential added to the battery poles forces the positive compounds to release lithium ions and embed the anode molecules into the...

How Lithium-ion Batteries Work
Mar , 23 2023
Lithium-ion batteries are popular because they have a number of important advantages over competing technologies: They're generally much lighter than other types of rechargeable batteries of the same size. The electrodes of a lithium-ion battery are made of lightweight lithium and carbon. Lithium is also a highly reactive element, meaning that a lot of energy can be stored in its at...

Cause of low-temperature attenuation of lithium iron phosphate battery
Mar , 10 2023
Lithium iron phosphate battery is a common type of lithium-ion battery, which has the advantages of high energy density, long cycle life, and no pollution, so it is widely used in electric vehicles, power tools and other fields. However, in a low-temperature environment, the performance of lithium iron phosphate battery will be degraded to a certain extent. The attenuation of lithium iron phosphat...

What are the possible reasons for the zero voltage or low voltage of the single cell and battery pack?
Oct , 24 2022
What are the possible reasons for the zero voltage or low voltage of the single cell? 01) External short circuit or overcharge or reverse charge of the battery (forced overdischarge); 02) The battery is continuously overcharged by high rate and high current, resulting in the expansion of the battery pole core, the direct contact of the positive and negative poles, and the short circuit; 03) Intern...

What kind of conditions are better for batteries to be stored in?
Oct , 24 2022
Can the battery be stored in the appliance after it is used up or if it is not used for a long time? If the electrical appliance will not be used for a long time, it is better to take the battery out and put it in a low temperature and dry place. If not, even if the electrical appliance is turned off, the system will still make the battery have a low current output, which will shorten the battery ...

What is the 24-hour self-discharge test and What precautions should be taken when using the battery?
Oct , 24 2022
What is the 24-hour self-discharge test? The self-discharge test of lithium battery is: generally use 24-hour self-discharge to quickly test its charge retention capacity, discharge the battery to 3.0V at 0.2C, charge it to 4.2V at constant current and constant voltage 1C, cut-off current: 10mA, set aside for 15 After one minute, discharge the battery at 1C to 3.0V to measure its discharge capacit...

What are the main factors that affect the battery life?
Oct , 24 2022
What is the rate discharge of the battery? What is the hourly rate discharge of the battery? Rate discharge refers to the rate relationship between discharge current (A) and rated capacity (A•h) during discharge. Hourly rate discharge refers to the number of hours required to discharge the rated capacity according to a certain output current. Can batteries of different capacities be combined? If d...
