An overview of the application of atomic layer deposition process for lithium‐ion based batteries

Abstract

Lithium-ion battery (LIB) systems provide a very promising range of power supply systems for diverse applications like electric vehicles, hybrid plug-in electric vehicles, grid storage systems, and microelectronics. Nevertheless, the features of lithium-ion batteries (LIBs), which include energy density and power, cycle lifetime, safety, as well as cost, must be enhanced in order to achieve all these feasible applications. Atomic layer deposition (ALD), as a result of its unique benefits above other thin-film methods of deposition, emerges as a very useful approach for use in improving the efficiency of LIBs. This review summarizes ALD's advanced successes in designing new nanostructured solid-state electrolytes and electrode materials, as well as the adjustment of the interfaces of electrodes and electrolytes through the application of surface coatings for the avoidance of undesirable side reactions to attain maximum adequate performance of the electrode. Also covered are ideas for the potential advancement of ALD studies and technology for the applications of LIBs. This review paper is anticipated to furnish researchers within the LIB and ALD fields with valuable information that would encourage much more extensive research on the use of ALD to produce new generation LIBs.Novelty Statement: This review presents the recent advancements in electrode materials as well as some new electrode fabrication processes for Li-ion batteries.

Atomic Layer Deposition Titanium Oxide Coating for C-Rate Improvement of Li-Ion Cathodes

“…The ALD application relevance in the LIB field is confirmed by already available studies of cathode synthesis and its coating by atomic layer deposition method; [5][6][7][8][9] our team also analyzed the literature about ALD application for cathode coating, which consider many compositions of coatings and regularities associated with their synthesis. 4 Based on the review, the titanium oxide protective coating, on par with aluminum oxide, has revealed its efficiency in preserving cathode capacity at elevated current strengths, high cycling potentials, elevated temperatures and long-term cycling.…”

A review on “Growth mechanisms and optimization strategies for the interface state of solid‐state lithium‐ion batteries”

“…Li + jumps from one polymer chain to another, thus realizing the transmission of Li + . [50][51][52] However, ion conduction can also be performed by a unique crystal structure in the polymer electrolyte. Pairs of polyethyleneoxide (PEO) chains are folded together to form a cylindrical channel.…”

“…Driven by the electric field, Li + complexed/dissociated with the polymer segment, and moved from the coordination position to a new position, or at high temperature, the polymer produced free volume through local segment movement. Li + jumps from one polymer chain to another, thus realizing the transmission of Li + 50–52 . However, ion conduction can also be performed by a unique crystal structure in the polymer electrolyte.…”

CFD Simulation of the Dosing Behavior within the Atomic Layer Deposition Feeding System

“…Atomic layer deposition (ALD) has found applications in a variety of areas, including semiconductors, 1 membranes, 2 catalysts, 3 and batteries. 4 As a thin-film deposition technique with atomic-level precision, ALD is based on sequential selfterminating reactions between gaseous precursors and solid substrates. Therefore, ALD can deposit thin films with exceptional conformality and uniformity on even high-aspectratio structures at the nanoscale.…”
