Applications and Advantages of Atomic Layer Deposition for Lithium-Ion Batteries Cathodes: Review

Nowadays, lithium-ion batteries (LIBs) are one of the most convenient, reliable, and promising power sources for portable electronics, tools, hybrid electric vehicles. The characteristics positive electrode (cathode active material, CAM) significantly contribute to battery’s functional properties. Applying various coatings is productive ways improve work batteries. there many methods depositing thin films on a material’s surface; among them, atomic layer deposition (ALD). ALD allows formation uniform surfaces with complex geometric forms, including porous structures. This review devoted applying method in obtaining cathode materials includes an overview more than 100 publications. thoroughly investigated surface modifications lithium cobalt oxide (LCO), manganese spinel (LMO), nickel-cobalt-manganese oxides (NCM), lithium-nickel-manganese (LNMO), lithium-manganese rich (LMR) materials. studied processes aluminum (Al2O3), titanium dioxide (TiO2) zirconium (ZrO2) films. primary purposes such studies find synthesis parameters films, optimal coating thickness (e.g., ~1–2 nm Al2O3, ~1 ZrO2, <1 TiO2, etc.), reveal effect electrochemical summarizes conditions, investigation results deposited CAMs electrodes some effects observed due obtained by cathodes.
