  Requirements for fast-charging lithium-ion batteries

  ●According to the structural characteristics of fast-charge lithium-ion batteries, the maximum charge termination voltage should be 4.2V, and overcharge is not allowed, otherwise the battery will be scrapped due to the removal of too much lithium ions from the positive electrode.

  ●Lithium-ion batteries have high requirements for charging and discharging, and special constant-current and constant-voltage chargers can be used for charging. Usually after the constant current charging reaches 4.2V/knot, it will switch to constant voltage charging. When the constant voltage charging current drops below 100mA, the charging should be stopped.

  ● Charging current (mA) = 0.1 to 1.5 times the battery capacity (for example, for a 2000mAh battery, the charging current can be controlled between 200 and 4000mA). The conventional charging current can be selected at about 0.5 times the battery capacity, and the charging time is about 2 to 3 hours.
