Separator, a vital component in LIBs, impacts the electrochemical properties and safety of the battery without association with electrochemical reactions. The development of innovative separators to overcome these countered bottlenecks of LIBs is necessitated to rationally design more sustainable and reliable energy storage systems.
Despite the advances that have been made in the development of separator materials, there are still several challenges that currently exist. These challenges are primarily due to new and emerging applications of Li-ion batteries. Among the existing challenges of the separator, the main ones are: 1. Wettability of the 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.
In these developments, the separator is a critical component of the batteries. This is because; it provides a physical barrier between the positive and negative electrodes. Doing so, it prevents electrical short circuits. In addition, the separator must be porous to allow for the effective transport of the lithium ions in the battery.
Currently, most commercial separators for lithium-ion batteries are typically porous polyolefin films, both polyethylene and polypropylene. These polymer separators are generally not compatible with some conventional electrolytes that include solvents of high dielectric constants, such as: This is due to the low surface energies of the polyolefins.
This means that the overall porosity of the separator and the average pore size will be higher and this can lead to an improvement in the wettability features of the separator. The drawback to this approach is that highly porous separators are quite weak and they can be very difficult to handle during battery fabrication processes.
