The charge and discharge of the polymer lithium-ion battery and the liquid lithium ion battery is actually communicated. It is important for constant pressure charging and constant current charging, or it can be held in both. In constant current charging, the battery capacity is new, and the internal resistance of the battery is also increasing, and charging is slow.
At this time, we don't think that charging is completed, but also the slow charging before the end of it. The general polymer lithium-ion battery's production manufacturers are charging the recycling constant current when charging the battery, and charging is held in recycling constant voltage current. Current, voltage and mobile phone power change in turn of change, so that the battery can be quickly covered.
Today's charging method of polymer lithium-ion battery is generally recovered constant current constant pressure charging: The battery is first charged at a constant current, and when the battery voltage rises to inevitable value (4.2V), the voltage remains stably CV. The current is low in the circuit.
Small, eventually tend to be 0. The polymer lithium-ion battery cannot be charged. If it has a large function of overcharge to the battery, the negative pole will appear, thereby probably causes the battery to explode or angle, and the solvent in the electrolyte occurs, resulting in serious battery machine Crush.
