  • 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...

  • 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...

  • 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...

  • 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...

  • Testing of lithium battery separators?

    As a core material of lithium-ion batteries, the performance of the diaphragm directly determines the interface structure and internal resistance of the battery, which directly affects the electrical performance of the battery. So what are the quality testing methods for the lithium battery diaph...
