“…The application of lithiophilic metals such as zinc and gold offers a beneficial effect on the reversible lithium deposition. 204 The corresponding alloys LiZn and Li 15 Au 4 , which are formed before lithium metal is deposited, do not serve as a passivating layer, but as they lower the overpotential of lithium deposition underneath themselves, they yield a smooth and homogeneous lithium deposition. Lithiophilic metals can be coated on copper substrates 205 for the use of lithiated cathode materials and on the surface of lithium metal by means of sputter coating 204 to enable the use of nonlithiated cathode materials (or simply to maintain a certain lithium reservoir to balance a non-ideal Coulombic efficiency).…”

“…Apart from electrolyte formulations, surface treatments can be applied prior to cell assembly. For instance, mechanical methods such as roll-pressing or micropatterning and chemical modifications by physical vapor deposition or immersion have been reported. − Roll-pressing “dilutes” the “native” film ( i.e. , the layer formed during lithium metal production and processing prior to contact with the electrolyte), which mainly consists of Li 2 O and Li 2 CO 3 , and smoothens the lithium metal, resulting in a more homogeneous surface .…”

Lithium metal batteries are gaining increasing attention due to their potential for significantly higher theoretical energy density than conventional lithium ion batteries. Here, we present a novel mechanochemical modification method for lithium metal anodes, involving roll-pressing the lithium metal foil in contact with ionic liquid-based solutions, enabling the formation of an artificial solid electrolyte interphase with favorable properties such as an improved lithium ion transport and, most importantly, the suppression of dendrite growth, allowing homogeneous electrodeposition/-dissolution using conventional and highly conductive room temperature alkyl carbonate-based electrolytes. As a result, stable cycling in symmetrical Li∥Li cells is achieved even at a high current density of 10 mA cm –2 . Furthermore, the rate capability and the capacity retention in NMC∥Li cells are significantly improved.

“…Beyond solution-based reactive treatments, physical vapor deposition methods such as sputter-coating were also applied to create the artificial Li-alloy interphase on LMA. [78][79][80][81] In this case, since metals were directly deposited, the surface phase was rigorously true Li-alloy interphase because solvents and counterions present in the solution-based treatments are no longer relevant. However, judging from the observed Li-deposition morphology and electrochemical reversibility, there seems to be no clear gap between a composite and a metallic Li-alloy interphase (Figure 4(A)).…”

A robust electrode-electrolyte interface is the cornerstone for every battery system, as demonstrated in the meandering history of the development of Li-ion batteries (LIBs). In the thrust to replace the graphite anode with more energetic ones in LIBs, the effectual strategy for stabilizing the original graphiteelectrolyte interface becomes obsolete and a new anode-electrolyte interface needs reconfiguration. Unfortunately, this interface has become the Achilles' heel for those anodes, such as Li-metal anode (LMA) and Si-based anode owing to their excessive reductivity, enormous volume change, and so forth. Encouragingly, in the last decade, impressive progress has been made on taming these extremely unstable interfaces and on the solid-state batteries (SSBs) that are reported to be less susceptible to parasitic reactions. One of the distinguished strategies is the application of artificial Li-alloying intermetallic interphases onto the surface of LMA, via the direct introduction of foreign metals to the Li anode or indirect hetero-cations doping in the electrolyte, to regulate the Li deposition/ stripping behavior, which has markedly improved the stability of the LMAelectrolyte interface. In parallel, the intermetallic interphases are also witnessed to profoundly enhance the anode-solid electrolyte contact and the corresponding charge transfer kinetics in various SSBs. This review will provide a panoramic overview of the application of the intermetallic interphases at the anode-electrolyte interfaces in the lithium metal batteries (LMBs), SSBs, and also derivative works in the conventional LIBs, which will focus on different concepts, methodologies, and understandings from the encircled studies.
