One of the main application targets of the alumina coated membranes is incorporating them within lithium-ion batteries (LIBs) as a separator. LIBs are widely considered the most promising energy storage technology due to their high energy density, long cycle life, and superior rate performance.
It has been proved that the surface coating technique could successfully alleviate the side reaction, which led the electrolyte decomposition in the lithium-ion batteries and stabilized the structure of the cathode material and improved its electrical conductivity.
These coatings, applied uniformly to critical battery components such as the anode, cathode, and separator, can potentially address many challenges and limitations associated with lithium-ion batteries.
Developing sustainable coating materials and eco-friendly fabrication processes also aligns with the broader goal of minimizing the carbon footprint associated with battery production and disposal. As the demand for lithium-ion batteries continues to rise, a delicate balance must be struck between efficiency and sustainability.
By mitigating the root causes of capacity fade and safety hazards, conformal coatings contribute to longer cycle life, higher energy density, and improved thermal management in lithium-ion batteries. The selection of materials for conformal coatings is the most vital step in affecting a LIB's performance and safety.
Separator membranes, a critical component of lithium-ion batteries, are responsible for storing the electrolyte, facilitating the transport of lithium ions between the positive and negative electrodes, and preventing internal short circuits, thus playing a vital role in the safety of these batteries [9, 10, 11, 12, 13].
