versus commercial graphite (372 mAh g −1 ) and lowest electrochemical potential (-3.04 V vs standard hydrogen electrode). [2] Nevertheless, Li metal-based cells manufactured in the 1980s had safety concerns stemming from the instability of the solid electrolyte interface (SEI) between the non-aqueous electrolyte and the Li metal, resulting in the inhomogenous and irrepressible deposition of Li ions, commonly known as Li dendrites. [3] The formation of Li dendrites can have catastrophic consequences: i) continuous formation of an SEI, resulting in eventual drying of the electrolyte upon cycling; ii) penetration through the pores of the pristine separator, resulting in short-circuiting, thermal runaway, and risk of explosion; and iii) detachment of dendritic Li from its roots, leading to the creation of dead Li and decreased coulombic efficiency. [4] These problems related to Li metal must be addressed before pairing it with counter electrodes in, for example, lithium sulfir (Li-S) and lithium oxygen (Li-O 2 ) batteries. [5] Much research has been conducted to understand the phenomenon of Li dendrite formation and to develop sustainable solutions to prolong the life of Li-metal batteries. The development of 3D porous frameworks for hosting Li, the formation of in situ SEI, optimizing the electrolyte, and fusion of an ex situ artificial SEI on the surface of Li metal (Al 2 O 3 , LiPO 3 , Li 3 N, graphene oxide) have all been useful in retarding the generation of Li dendrites. [6] Newer approaches toward countering Li dendrite formation have included incorporating biomacromolecule interlayers and immunizing Li metal with protein molecules. [7] Furthermore, modifying the pristine separators with various organic and inorganic coatings and employing various interlayers to homogenize the Li-ion flux have been beneficial in controlling Li dendrite growth. [8] Coating the Li metal surface with fluoropolymers, graft coatings, soft self-healing coatings, and generating high interfacial energy with SrF 2 rich SEI can lead to high capacities and high rates of Li deposition, with ease of processing. [9] Nevertheless, the understanding of the effect of these coating layers on the development, modification, and formation of SEIs or the deposition and stripping of Li during prolonged cycling is not yet fully known. [10] The notorious growth of lithium ( Li) dendrites and the instability of the solid electrolyte interface (SEI) during cycling make Li metal anodes unsuitable for use in commercial Li-ion batteries. Herein, the use of simple sugar coating (α-d-glucose) is demonstrated on top of Li metal to halt the growth of Li dendrites and stabilize the SEI. The α-d-glucose layer possesses high surface and adhesive energies toward Li, which promote the homogenous stripping and plating of Li ions on top of the Li metal. Density functional theory reveals that Li-ion diffusion within the α-d-glucose layer is governed by hopping around the bare sides of the O atoms and along the apparent passages formed by the glucose molecule...
