How to judge the quality of lithium ion battery cells 18650
How to judge the quality of UPS lithium battery?
As for the quality of lithium ion battery cells 18650, our general approach is to use professional testing instruments to judge, but this kind of specialized instrumentation is not available to users.
1. Simple identification from the surface. It is just like the four diagnosis methods in traditional Chinese medicine. When observing, first of all, you need to look at the consistency of the surface. For example, if there is any deformation or protrusion in the appearance of the lithium battery UPS, if this happens, it means that the internal structure of the lithium battery has been damaged, which is the first priority. Picked teams must be cleared.
2. In addition to observing deformation, also check for leaks, cracks, bursts, burning, or internal liquid exposed at screw connections. Generally, this type of battery has major quality issues. Not only the lithium battery UPS of this batch with defective appearance cannot be selected, but also the batteries from the same manufacturer are not recommended to be selected to avoid production safety accidents and various kinds of rechargeable batteries during use. Various common faults.
3. The internal load must be accurately measured. When it is clear that there is no abnormality in the appearance, the next step is usually to make the lithium battery UPS bear a certain load when it is in working mode. If the charging and discharging time of the lithium battery UPS cannot meet all requirements, If the normal charging and discharging time or the battery still cannot respond to the normal reserve time after sufficient charging time, it means that the battery has aged and can no longer meet our daily use needs of lithium batteries.
High-rate batteries generally refer to lithium batteries. Lithium-ion batteries are rechargeable high-rate batteries that mainly rely on lithium ions to move between the positive and negative electrodes to work. During the charge and discharge process, Li+ is intercalated and deintercalated back and forth between the two electrodes: when charging the battery, Li+ is deintercalated from the positive electrode and embedded in the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; when discharging, the opposite is true. Batteries generally use materials containing lithium as electrodes. It is a representative of modern high-performance batteries. So what does the lithium battery battery hour rate and rate mean?
The hour rate is the discharge rate expressed in terms of discharge time, that is, the time it takes to discharge the rated capacity with a certain current. For example, the Dongfeng brand EQl090E automobile lithium battery has a rated capacity of 105Ah for 20 hours, that is, C=105Ah. The lithium battery should be discharged at a current of 105÷20=, and the battery that reaches 20 hours continuously is qualified.
The magnification ratio refers to the multiple of the discharge current value of a certain battery to the rated capacity value. For the above EQl090E automotive lithium battery 6-Q-105, if the discharge current is expressed as, it is discharged with a current of =; if the discharge current is expressed as 3CA, it is discharged with a current of 3X105=315A.
Termination voltage refers to the lowest operating voltage when the voltage of the battery drops to the point where it is no longer suitable to continue discharging. Generally, the discharge termination voltage under high rate and low temperature conditions is set lower. Things to note when using high-rate batteries: 1. Storage requirements: In an environment with a temperature of 25±5°C and a humidity of no more than 50%, the erosion of the aluminum foil by air and water vapor must be avoided during transportation; 2. The carbon layer The heat dissipation is worse than that of aluminum foil, so the belt speed and baking temperature need to be fine-tuned appropriately when coating.
