The primary function of separators is to prevent physical contact between the anode and the cathode while permitting ion transport. Therefore, the enhancement of the properties of separators, such as electrolyte uptake, thermal stability, and ionic conductivity, directly influences the battery efficiency.
The literature on lithium metal battery separators reveals a significant evolution in design and materials over time . Initially, separators were basic polymer films designed for lithium-ion batteries, focusing primarily on preventing short-circuits and allowing ionic conductivity [, , ].
Therefore, the two safety guarantee properties of the composite separator greatly enhance the safety and service life of the battery, which allows the application of lithium batteries to be further improved in the application scenario and application scale.
Integrating numerical and experimental analysis is an essential and effective way to develop reliable and remarkable lithium metal batteries. In summary, with the advancements in materials science and design methods, the role of separators in lithium metal battery technology has been greatly emphasized.
The separator plays a key role in battery construction because it functions as the physical barrier to prevent electronic contact between the two electrodes and at the same time serves as an electrolyte reservoir, facilitating the ionic conduction.
For instance, the electrolyte uptake enhancement significantly affects the electrochemical stability of battery cells. To achieve the high performance of LIBs, incorporating inorganic materials into the conventional PP separators is beneficial, as these particles can improve the electrolyte uptake by enhancing the surface area of separators.
