Fast charging can cause some damage to the battery. When the battery is fast charging, due to the large current, the thermal effect of the current will be aggravated, resulting in a rise in battery temperature, which affects the safety and stability of the mobile phone, resulting in a sudden drop in capacity, causing permanent damage to the battery cell. And fast charging will also destroy the chemicals on the battery and shorten the battery life. At present, the fast charging technology on the market is mainly divided into high voltage fast charging and low voltage fast charging. Low voltage fast charge is widely used in the market. In principle, the damage of fast charging to the battery basically comes from two aspects. When the battery is charged and discharged, the positive and negative electrodes of the battery contract and expand as ions are released and absorbed. Fast charging destroys the chemicals on the battery, which shortens its life. When the battery is rapidly charging, due to the large current, the thermal effect of the current will be intensified, resulting in a rise in battery temperature, which affects the safety and stability of the mobile phone, resulting in a sudden decline in capacity, causing permanent damage to the battery cell.
