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.
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.
In the conventional lithium-ion battery electrode preparation process, wet coating technology is widely used. Coating means depositing the electrode active material, such as LFP, on a conductive aluminum or copper foil.
The electrode is one of the most important components in lithium-ion batteries. It determines the capacity and overall performance of the battery. The fabrication process of electrodes mainly involves several steps, among which the coating process refers to the process of evenly spreading the active material on the current collector.
Major recommendations to enhance further battery research are discussed. Nickel-rich NMC (LiNi x Mn y Co 1−x−y O 2, x ⩾ 0.8) electrode materials are known for their great potential as lithium battery cathode active materials due to their high capacities, low cost, and environment friendliness.
These techniques can be widely used to form suitable conformal coatings on electrode materials to reduce the electrolyte-electrode side reactions, reduce self-discharge reactions, improve thermal and structural stability, increase the conductivity of electrodes, and thus further enhance the battery performance.
