For example, the stretching conditions that are used to produce the separators can be modified to yield higher porosity products. 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

A separator is an essential part of the battery and plays a vital role both in its safety and performance. Over the last five years, cellulose-based separators for lithium batteries have drawn a lot of interest due to their high thermal stability, superior electrolyte wettability, and natural richness, which can give lithium batteries desired safety and performance improvement.
Cellulose-based separators have received increasing attention in rechargeable batteries because of advantages including high-temperature resistance, high electrolyte affinity, renewability, and the ability to suppress the shuttle effect.

It should have good permeability and good wetting ability for the electrolyte to ensure lower resistance and higher ion conductivity of the separator, improving the electrochemical performance of the battery. Nowadays, most of the commercially used separators are polyolefin, such as polypropylene (PP) and polyethylene (PE).
The main role of a battery separator is to allow the safe movement of ions. This is what makes the battery charge up your electronic device. The movement of electrons from the anode to the cathode happens when the battery is charging. And when the electrons move in the reverse, from cathode to anode, the battery is discharging.
The dry process is commonly employed for manufacturing ceramic-based battery separators. Powder Mixing: The first step in the dry process is to mix the ceramic powders with binders and additives. The composition of the mixture is carefully controlled to achieve the desired properties in the final separator.

The battery separator must be porous to allow transportation of the lithium ions. The performance and efficiency of Lithium-ion batteries rely on separator properties and structure. What Is the Function of a Battery Separator? A battery separator’s function is to guarantee safety by avoiding short circuits. But that’s not all.
These modern separators prevent short circuits, enhance ion conduction, and provide thermal stability. They are now essential in various applications, from lithium-ion and lead-acid batteries to electric vehicles and portable electronics. The performance, safety, and longevity of a battery largely depend on the quality of its separator.
