Using atomic layer deposition to hinder solvent decomposition in lithium ion batteries: first principles modeling and experimental studies
Kevin Leung,Yue Qi,Kevin R. Zavadil,Yoon Seok Jung,Yoon Seok Jung,Anne C. Dillon,Andrew S. Cavanagh,Se-Hee Lee,Steven M. George +8 more
TL;DR: Ab initio molecular dynamics simulations conducted at liquid EC electrode interfaces are consistent with the view that reactions and electron transfer occur right at the interface, and microgravimetric measurements demonstrate that the ALD coating decreases electrolyte decomposition and corroborates the theoretical predictions.

Improvement of the Cathode Electrolyte Interphase on P2-Na2/3Ni1/3Mn2/3O2 by Atomic Layer Deposition
TL;DR: For the first time, X-ray photoelectron spectroscopy is used to elucidate the cathode electrolyte interphase (CEI) on ALD-coated electrodes, which contains less carbonate species and more inorganic species, resulting in significant increase in Coulombic efficiency and decrease in cathode impedance.
Ultrathin Al2O3 Coatings for Improved Cycling Performance and Thermal Stability of LiNi0.5Co0.2Mn0.3O2 Cathode Material
TL;DR: The capacity retention of the coated cathode is 76.8% after 30 cycles in the voltage range of 2-4.8 V, compared to 58.4% of pristine cathode.

Enhancing the High-Voltage Cycling Performance of LiNi0.5Mn0.3Co0.2O2 by Retarding Its Interfacial Reaction with an Electrolyte by Atomic-Layer-Deposited Al2O3
TL;DR: It is found that the ultrathin ALD Al2O3 film can reduce the interface resistance of lithium-ion diffusion and enhance the surface stability of NMC532 by retarding the reactions at Nmc532/electrolyte interfaces for preventing the formation of a new microstructure rock-salt phase NiO around the N MC532 surfaces.
