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.
Unfortunately, most studies in the field of lithium-based batteries have only focused on separators between 20-25 μm so as to achieve a balance between battery safety and performance.
As a result, the CA@2500 separator could achieve uniform deposition and protect the lithium cathode theoretically. Conversely, the original 2500 separator became susceptible to nonuniform lithium deposition, and it subsequently gave rise to uncontrolled lithium dendrites.
In the 2500 separator, the conduction of Li + was disturbed by its solvation group. As a result, lithium ions showed slow diffusion and migration characteristics in the 2500 separator battery.
The porosity is definitely the basic requirement for separators of lithium-based batteries to transport Li ions. A sufficient amount of liquid electrolyte should be trapped within micro pores and interconnected channels in separator to sustain a high ion conductivity.
Over time, the battery with 2500 separators showed obvious polarization. This phenomenon was caused by the continuous loss of electrolyte and the formation of lithium dendrites . Hence, the CA@2500 separator enabled stable lithium plating and stripping by regulating ion transport in proximity to the lithium metal.
