Cause analysis and solutions for common problems of lithium batteries
1. The voltage is inconsistent, some of the voltage is low 1. Large self-discharge will cause low voltage The self-discharge of the battery is large, so its voltage drops faster than other batteries. The low voltage can be eliminated by checking the stored voltage. 2. Uneven charging will cause l...Read more -
The characteristics and advantages of polymer lithium batteries
The three elements of an ordinary battery: positive electrode, negative electrode and electrolyte. The so-called polymer lithium battery refers to a battery system in which at least one or more of the three elements uses polymer materials. In lithium polymer battery systems, most polymer material...Read more -
Advantages, disadvantages and characteristics of lithium batteries
Advantages 1. The energy is relatively high. The energy storage density is high, reaching 460-600Wh/kg, which is about 6-7 times that of traditional lead-acid ion batteries; 2. With lithium iron phosphate as the positive electrode, the battery is charged and discharged at 1C (100% DOD). There are...Read more -
Technical requirements of aluminum-plastic film for polymer lithium battery packaging
As the main part of the cell’s internal isolation from the external environment, the aluminum film used in the packaging of lithium batteries not only has a certain mechanical strength to the external environment, but also has excellent chemical corrosion resistance to the internal chemicals. The...Read more -
Factors affecting the discharge performance of high-rate lithium batteries
1. In high-rate lithium batteries, the capacity of the thin positive electrode is lower than that of the thick positive electrode. When discharging at the same rate, the current density flowing through the positive electrode is different. Under the same rate, the current density flowing through t...Read more -
