The properties of separators have direct influences on the performance of lithium-ion batteries, therefore the separators play an important role in the battery safety issue.
A high safety separator is essential to improve the safety of lithium-ion batteries. This review summarizes its performance requirements and preparation methods. All the separator requirements have a synergistic effect on the electrochemical performance, safety, and scalability of lithium-ion batteries.
The structure and performance of the battery separator significantly influence the cycle life, energy density, and safety of the lithium-ion battery. Separator is located between the positive electrode and the negative electrode to prevent electric short-circuiting.
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.
Current and emerging characterization techniques will play an important role in guiding this evolution in separator technology. Separators are an essential part of current lithium-ion batteries.
