  • The correct maintenance method of lithium ion battery

    1. The newly purchased lithium-ion battery has very little power, so when the user gets the battery, it can be used directly and recharged after the remaining power is used up. After 2 to 3 times of normal use, lithium ions can be fully activated. 2. Prevent frequent overcharging. Qualified charg...

  • 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...

  • 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...
