Structure, Function, and Application
The main difference between battery cells and batteries lies in their structure, function, and application. The battery cell is the core part of a battery, usually composed of one or more positive and negative electrodes, separators, and electrolyte. Its structure is simple, usually cylindrical or square. A battery, on the other hand, is composed of multiple cells and has a complex structure, usually including multiple parts such as cells, circuit boards, and casings.
The main function of a battery cell is to convert chemical energy into electrical energy and store it, while a battery is an electrical energy storage device composed of multiple cells. Its main function is to store electrical energy and release it for use when needed.
In terms of application, the battery cell is the most fundamental and core part of the battery. A battery pack is composed of multiple battery cells, which then form a battery.
For devices such as Apple phones, replacing battery cells can solve the problem of battery durability, while retaining the original battery health display and avoiding pop-up prompts. The replacement of battery cells requires attention to turning off battery optimization and charging according to a certain number of cycles to restore the capacity of the battery cells.
In summary, the main difference between battery cells and batteries lies in their structure, function, and application. The battery cell is the core part of the battery, and the battery adds safety measures such as protective casing and control circuit on the basis of the battery cell.
