Effect of Cell Separator on Battery Performance
The Role of Cell Separator
The cell separator is an important part of the battery. It is located between the positive electrode and the negative electrode to isolate the electrodes and prevent short circuits.
The cell separator has a great influence on the performance of the battery, mainly including the following aspects:
(1) Battery safety
The cell separator can effectively prevent the short circuit and overcharge and discharge of the battery, thereby improving the safety of the battery.
(2) Battery capacity
The thickness and pore size of the cell separator will affect the electrolyte diffusion rate and electron transport rate of the battery, thereby affecting the capacity of the battery.
(3) Battery cycle life
The quality and stability of the cell separator will affect the cycle life of the battery, and a better cell separator can prolong the service life of the battery.
(4) Battery internal resistance
The thickness and pore size of the cell separator will also affect the internal resistance of the battery. Lower internal resistance can improve the output power and charge and discharge efficiency of the battery.
Therefore, the cell separator is one of the key factors of battery performance, which has an important impact on the safety, capacity, cycle life and internal resistance of the battery.
