Customer ServiceThe separator is one of the most critical inner layer components in the structure of lithium batteries. The quality of its performance directly affects the capacity, rate, life and safety of the battery. It actively contributes to the thermal stability of your lithium-ion battery.
The small amount of current that may pass through the separator is self-discharge and this is present in all batteries to varying degrees. Self-discharge eventually depletes the charge of a battery during prolonged storage. Figure 1 illustrates the building block of a lithium-ion cell with the separator and ion flow between the electrodes.
Separators in Lithium-ion (Li-ion) batteries literally separate the anode and cathode to prevent a short circuit. Modern separator technology also contributes to a cell’s thermal stability and safety. Separators impact several battery performance parameters, including cycle life, energy and power density, and safety.
Although ions pass freely between the electrodes, the separator is an isolator with no electrical conductivity. The small amount of current that may pass through the separator is self-discharge and this is present in all batteries to varying degrees. Self-discharge eventually depletes the charge of a battery during prolonged storage.
Desired Characteristics of a Battery Separator One of the critical battery components for ensuring safety is the separator. Separators (shown in Figure 1) are thin porous membranes that physically separate the cathode and anode, while allowing ion transport.
There are different types of battery separators, and each type of battery uses its type of separators. The only battery that does not need a separator is the solid-state lithium-ion battery. Battery isolators and separators are different in that a battery isolator is one-directional and prevents battery over-discharge.
