“…A distribution of lithiophilic sites around a 3D structure is able to accommodate a higher amount of lithium than a planar structure as demonstrated by Zhao et al [113] Many CCs use protective layer coatings such as multilayer graphene (MLG), reduced graphene oxide (r-GO), and multiwalled carbon nanotubes (CNTs), alloy compounds, to guide uniform and compact Li nucleation due to their lithiophilicity and good electrical conductivity. [114,115] Modification of CCs, including suitable host structures in combination with lithiophilic coatings shows great promise to be an enable option for increasing reversibility and achieving higher CE close to 100%. In brief, the following sections will discuss more CC modifications of different materials used for AFLMBs and AFSSBs applications.…”

Current lithium (Li)‐metal anodes are not sustainable for the mass production of future energy storage devices because they are inherently unsafe, expensive, and environmentally unfriendly. The anode‐free concept, in which a current collector (CC) is directly used as the host to plate Li‐metal, by using only the Li content coming from the positive electrode, could unlock the development of highly energy‐dense and low‐cost rechargeable batteries. Unfortunately, dead Li‐metal forms during cycling, leading to a progressive and fast capacity loss. Therefore, the optimization of the CC/electrolyte interface and modifications of CC designs are key to producing highly efficient anode‐free batteries with liquid and solid‐state electrolytes. Lithiophilicity and electronic conductivity must be tuned to optimize the plating process of Li‐metal. This review summarizes the recent progress and key findings in the CC design (e.g. 3D structures) and its interaction with electrolytes.

“…Figure b shows that the huge electrochemical window of garnet SSEs (CV measurements show >6 V versus Li/Li + , whereas computational analysis shows only 3 V) paves the way for the creation of high-voltage batteries . However, the thermodynamic stability of garnet SSEs in the presence of Li metal and certain cathode materials has been the subject of theoretical investigations based on bulk-phase thermodynamic data . Still, some of the most promising are garnet SSEs because of their reliability and potential usefulness.…”

To surmount constraints, the increasing demand for electric vehicles and networks necessitates the use of lithium-ion batteries (LIBs) that traditionally use electrolytes that are volatile organic liquids (LEs). Increasing demand for electric networks and automobiles necessitates safer batteries in the presence of more energy. Lithium solid-state batteries (SSBs) have recently gained popularity as alternatives to LEs. However, the interface instability between solid electrolytes (SEs) and electrodes limits the energy density of SSBs. With parasitic reactions and dendrite growth, this culminates in a short cycle life and a dissatisfied coulombic efficiency. Significant advancements have been made in the field of SEs. Nevertheless, substantial challenges still exist that prevent the practical use of SSBs with high energy densities. This review summarizes the most current findings in the study of electrolytes. Basic comprehension of the mechanism, scientific obstacles, and solutions to electrolyte limitations for high-performance SSBs are covered. Numerous strategies for addressing interface issues are analyzed, and as a result, some recommendations are made regarding the optimal electrolyte characteristics for practical applications. At the end of this review, key concerns and proposals for future study into how best to develop high-performance lithium SSBs are discussed.

“…Several Sn-based configurations have been explored to counteract the effects of volume expansion during electrochemical cycling, with the most widely explored strategies involving the incorporation of nanoscaled carbonaceous materials (like graphenic carbon and carbon nanotubes) as a “buffer” and the reduction of the particle size of Sn to nanoscaled dimensions. − Even though such strategies appear to be promising, the carbonaceous materials often act as dead weight, with the nanoscaled dimensions lowering the overall tap density and accruing deleterious irreversible reactions at the electrode/electrolyte interfaces. Furthermore, developing such materials and ensuring the attainment of the desired Sn/graphene interface characteristics are neither facile nor scalable.…”

Tin (Sn)-based anodes for sodium (Na)-ion batteries possess higher Na-storage capacity and better safety aspects compared to hard carbon -based anodes but suffer from poor cyclic stability due to volume expansion/contraction and concomitant loss in mechanical integrity during sodiation/ desodiation. To address this, the usage of nanoscaled electrodeactive particles and nanoscaled-carbon-based buffers has been explored, but with compromises with the tap density, accrued irreversible surface reactions, overall capacity (for "inactive" carbon), and adoption of non-scalable/complex preparation routes. Against this backdrop, anode-active "layered" bismuth (Bi) has been incorporated with Sn via a facile-cum-scalable mechanicalmilling approach, leading to individual electrode-active particles being composed of well-dispersed Sn and Bi phases. The optimized carbon-free Sn−Bi compositions, benefiting from the combined effects of "buffering" action and faster Na transport of Bi, to go with the greater Na-storage capacity and lower operating potential of Sn, exhibit excellent cyclic stability (viz., ∼83−92% capacity retention after 200 cycles at 1C) and rate capability (viz., no capacity drop from C/5 to 2C, with only ∼25% drop at 5C), despite having fairly coarse particles (∼5−10 μm). As proven by operando synchrotron X-ray diffraction and stress measurements, the sequential sodiation/desodiation of the components and, concomitantly, stress build-ups at different potentials provide "buffering" action even for such "active−active" Sn−Bi compositions. Furthermore, the overall stress development upon sodiation of Bi has been found to be significantly lower than that of Sn (by a factor of ∼3.8), which renders Bi promising as a "buffer" material, in general. Dissemination of such complex interplay between electrode-active components during electrochemical cycling also paves the way for the development of high-performance, safe, and scalable "alloyingreaction"-based anode materials for Na-ion batteries and beyond, sans the need for ultrafine/nanoscaled electrode particles or "inactive" nanoscaled-carbon-based "buffer" materials.
