1, battery aging: the chemical reaction speed inside the polymer lithium battery slows down, the performance of electrode materials and electrolyte changes, resulting in a decline in battery capacity, unable to provide enough power supply to drive the air pump equipment.
2, life depletion: When the life of the lithium polymer battery is close to the end, its performance will gradually decline, the battery capacity decreases, and can not provide enough power to support the normal work of the device.
