What is a battery separator?
The battery separator is one of the most essential components that highly affect the electrochemical stability and performance in lithium-ion batteries. In order to keep up with a nationwide trend and needs in the battery society, the role of battery separators starts to change from passive to active.
Are battery separators active or passive?
In order to keep up with a nationwide trend and needs in the battery society, the role of battery separators starts to change from passive to active. Many efforts have been devoted to developing new types of battery separators by tailoring the separator chemistry.
What is a rechargeable battery separator?
Separator is critical to the performance and safety of the rechargeable batteries. The design principles and basic requirements for separators are overviewed. The modification strategies in tailoring the separators' properties are discussed. Separators with high-temperature resistivity and better safety are desirable.
Why are battery separators important?
Another important part of a battery that we take for granted is the battery separator. These separators play an important role in deciding the functionality of the battery, for examples the self-discharge rate and chemical stability of the battery are highly dependent on the type of separator used in the battery.
Do battery separators affect battery performance?
Battery separators indeed affect the performance of your battery. For example, the Li-ion battery's separator directly affects how the battery performs. The separator is one of the most critical inner layer components in the structure of lithium batteries.
What is a nonwoven battery separator?
A nonwoven battery separator is a type of separator used in batteries that is lightweight, flexible, and exhibits good resistance to acid and electrolyte degradation. These separators are commonly employed in batteries such as nickel-metal hydride (NiMH) batteries and alkaline batteries.
