Affected by the use of nickel-metal hydride batteries, many people still like to completely recharge the mobile phone battery before recharging. For lithium batteries, this does not prevent the memory effect, and the lithium element has insufficient activity when the power is used up and then recharged, which will affect the battery capacity for a long time.

The memory effect is an effect that the battery contents crystallize due to the use of the battery. Generally, it only occurs in nickel-cadmium batteries, and nickel-hydrogen batteries are less. The reason for this is that the batteries are repeatedly charged and discharged incompletely. The temporary capacity of the battery is reduced, resulting in shortened talk time, so the nickel-cadmium battery needs to be fully charged to slow down the decline, while the lithium battery does not need to be used, recharge, no memory.

According to different electrolyte materials used in lithium ion batteries, lithium ion batteries are classified into liquid lithium ion batteries (Liquified Lithium-Ion Battery, referred to as LIB) and polymer lithium ion batteries (Polymer Lithium-Ion Battery, referred to as PLB).

The answer is that the battery needs to be activated, but this is not what the user has to do. I have visited the production plant of lithium-ion batteries. Before leaving the factory, the lithium-ion batteries go through the following process: the lithium-ion battery shell is filled with electrolyte-sealing-formation, which is constant voltage charging, and then discharging. This is done for several cycles to make The electrode is fully immersed in the electrolyte and fully activated until the capacity meets the requirements. This is the activation process-capacity division, which is to test the capacity of the battery. Select batteries of different performance (capacity) to classify, classify the battery, and perform capacity matching. The lithium-ion battery thus produced has already been activated to the user.
