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.
A major function of surface coatings in conventional lithium-ion batteries (discussed in section 3) is to provide a physical barrier between cathode and liquid electrolyte and thus suppressing the un-wanted side reactions, which may result in the formation of unstable SEI layer.
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.
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.
The copper coating acts as an upper current collector for a lithium metal, which reduces the local current density by increasing the surface area of lithium deposition, provides more electron transfer for dead lithium, and reduces the loss of battery capacity to a certain extent.
Dry coating technology, as an emerging fabrication process for lithium-ion batteries, with the merits of reducing energy consumption, reducing manufacturing cost, increasing production speed and capability of producing clean, high-capacity electrodes, is gradually attracting more and more attention.
