“…New organic components have also been developed for the purely organic MLD processes; the MLD material library already includes, besides the initially introduced polyimides [ 15,17–22,137–143 ] and polyamides, [ 15,23–28,144–149 ] many other polymers: polyurea, [ 29,30,37,38,51,150–164 ] polythiourea, [ 52 ] polyurethane, [ 165,166 ] polyazomethine, [ 167–172 ] poly(3,4‐ethylenedioxy‐thiophene), [ 173–177 ] polyimide–polyamide, [ 141 ] poly(ethylene terephthalate) (PET), [ 50,178–180 ] and others.

organic ligands act as bridges between the metal centers to form infinite 1D, 2D, or 3D structures. These materials are often referred to as coordination polymer (CP) [1] or metal-organic framework (MOF) [2] materials; the latter term is used when the metal-organic material is crystalline and highly porous. [3] The research field of CP-and MOF-type materials has grown tremendously over the last two decades. The structural and chemical diversity of these materials has served as a continuous source of scientific excitement; the same diversity has also triggered huge technological interest as these materials possess enormous potential to be tailored for a wide variety of applications ranging from gas capture, storage, and separation to sensing, catalysis, optics, electronics, and energy storage. [4][5][6][7] Most of the targeted application breakthroughs of metal-organics require that these materials can be produced as highquality thin films and coatings, which can be integrated with the other components in the actual device configuration. The possibility to deposit such thin films in an industry-feasible manner on the substrate types needed, would be a major step forward in the field. [8] Traditionally, solvent-based processes such as liquid-phase epitaxy, Langmuir-Blodgett, layer-by-layer, and electrochemical deposition techniques have been used for metal-organic thin films. [9][10][11] These are, however, incompatible with the requirements set by the possible integration of the materials in microelectronics. This is due to corrosion and contamination risks, and the problems in patterning and precise deposition on high-aspect-ratio features. Hence, it is vital to develop solventfree thin-film deposition routes for the metal-organic material family. In the optimal case, these deposition methods should allow conformal coatings on large-area and high-aspect-ratio substrates.The currently strongly emerging ALD/MLD technique is uniquely suited to address the challenge in a scientifically elegant yet industrially feasible way. This technique is derived from the two parent gas-phase thin-film techniques: ALD for inorganic materials (mostly binary metal oxides, sulfides, and nitrides), [12][13][14] and its counterpart MLD for purely organic thin films (e.g., polyimides and polyamides). [15] In both cases, the attractive film growth characteristics are derived from the unique way of separating the different precursor gas pulses. Currently, ALD is the standard thin-film technology in many Atomic layer deposition (ALD) for high-quality conformal inorganic thin films is one of the cornerstones of modern microelectronics, while molecular layer deposition (MLD) is its less-exploited counterpart for purely organic thin films. Currently, the hybrid of these two techniques, i.e., ALD/MLD, is strongly emerging as a state-of-the-art gas-phase route for designer's metal-organic thin films, e.g., for the next-generation energy technologies. The ALD/MLD literature comprises nearly 300 original journal papers covering most of the alkali...

“…), has become the most effective strategy to tune SEI in practical applications. In this way, many unique SEI or CEI can be formed on the anode (e.g., graphite, [ 12 ] Si/C‐based anode [ 13 ] ) and the cathode (e.g., LiNi 1‐x‐y Co x Mn y O 2 , [ 14 ] high voltage cathode [ 15 ] ) in the lithium‐ion batteries (LIBs), boosting the stability and reliability of LIBs significantly. Moreover, the same strategies can be also applied to construct the SEI on lithium metal and other electrodes in lithium batteries, [ 16 , 17 ] as well as other kinds of metal‐ion batteries (e.g., Na + , [ 1c ] K + , [ 18 ] Zn 2+ , [ 19 ] etc.).…”

Engineering the solid electrolyte interphase (SEI) that forms on the electrode is crucial for achieving high performance in metal-ion batteries. However, the mechanism of SEI formation resulting from electrolyte decomposition is not fully understood at the molecular scale. Herein, a new strategy of switching electrolyte to tune SEI properties is presented, by which a unique and thinner SEI can be pre-formed on the graphite electrode first in an ether-based electrolyte, and then the as-designed graphite electrode can demonstrate extremely high-rate capabilities in a carbonate-based electrolyte, enabling the design of fast-charging and wide-temperature lithium-ion batteries (e.g., graphite | LiNi 0.6 Co 0.2 Mn 0.2 O 2 (NCM622)). A molecular interfacial model involving the conformations and electrochemical stabilities of the Li + -solvent-anion complex is presented to elucidate the differences in SEI formation between ether-based and carbonate-based electrolytes, then interpreting the reason for the obtained higher rate performances. This innovative concept combines the advantages of different electrolytes into one battery system. It is believed that the switching strategy and understanding of the SEI formation mechanism opens a new avenue to design SEI, which is universal for pursuing more versatile battery systems with greater stability.
