Lithium battery life The reason for the slow charging speed

Dec , 13 2024

1. Electrical problems: Insufficient power of the charger is one of the common reasons for slow charging speed. If the output current of the charger used is small and cannot meet the maximum charging current requirements of the battery, the charging speed will be limited. For example, a lithium battery mobile phone that supports fast charging, the original charger output current is 3A, and the cha...

Causes and methods of lithium battery life decline

Dec , 13 2024

1. Battery aging: After multiple charge and discharge cycles, the chemical substances inside the lithium battery will gradually undergo irreversible changes. For example, the structure of the electrode material may be damaged when lithium ions are embedded and deembedded between the positive and negative electrodes. Taking the common lithium cobalt oxide cathode material as an example, with the in...
