“…The Mg 2+ and NO Besides coating on the top surface of LMA, another way to generate the Li-alloy interphase is by doping the entire LMA with a small quantity of alloying metals/metalloids. [86][87][88][89] In this case, the alloy anode is inherently bestowed with the Li-alloy interphase because the doping metal permeates the entire anode body. As a matter of fact, the borderline between this kind of LMA and a conventional alloy anode is relatively vague, but a plausible difference might be whether the anode is designed to work in the regime where Li-plating will definitely happen, and generally, in the former case, the doping metals also assume less than 20% of the total weight.…”

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.

“…22,23 Among these methods, uniformly distributed lithiophilic epicenters on the electrode are critical for improving the initial nucleation and uniform lithium deposition. [24][25][26][27] It has been found that heteroatomdoping (e.g. N, B, O) is one available strategy that can be used to improve the lithiophilicity of the anode.…”

“…With the booming development of electrical equipment, the demand for next-generation power sources with super-high capacities has become extremely strong. [1][2][3][4][5][6][7][8][9][10] Li-air cells offer a tantalizing solution to this issue, since they possess super-high energy densities. 11 Li-air cells, which generally comprise a Li electrode, organic solution, and a catalytic electrode, have attracted lots of attention in recent years.…”
