Engineering heterogeneous composite electrodes consisting of multiple active components for meeting various electrochemical and structural demands have proven indispensable for significantly boosting the performance of lithium‐ion batteries (LIBs). Here, a novel design of ZnS/Sn heterostructures with rich phase boundaries concurrently encapsulated into hierarchical interconnected porous nitrogen‐doped carbon frameworks (ZnS/Sn@NPC) working as superior anode for LIBs, is showcased. These ZnS/Sn@NPC heterostructures with abundant heterointerfaces, a unique interconnected porous architecture, as well as a highly conductive N‐doped C matrix can provide plentiful Li+‐storage active sites, facilitate charge transfer, and reinforce the structural stability. Accordingly, the as‐fabricated ZnS/Sn@NPC anode for LIBs has achieved a high reversible capacity (769 mAh g−1, 150 cycles at 0.1 A g−1), high‐rate capability and long cycling stability (600 cycles, 645.3 mAh g−1 at 1 A g−1, 92.3% capacity retention). By integrating in situ/ex situ microscopic and spectroscopic characterizations with theoretical simulations, a multiscale and in‐depth fundamental understanding of underlying reaction mechanisms and origins of enhanced performance of ZnS/Sn@NPC is explicitly elucidated. Furthermore, a full cell assembled with prelithiated ZnS/Sn@NPC anode and LiFePO4 cathode displays superior rate and cycling performance. This work highlights the significance of chemical heterointerface engineering in rationally designing high‐performance electrodes for LIBs.

“…Wang's group also reported the nano‐encapsulating electrode materials based on nitrogen‐doped hollow porous carbon spheres (N‐HPCSs) to tackle the major hurdles for the practical application of LMAs. [ 34 ] The thin N‐rich dense layer on the inner surface of N‐HPCSs can induce the preferential nucleation of metallic Li inside the hollow sphere. A highly reversible and repeatable plating/stripping cycling can be also achieved due to the specific structural design and stable Li encapsulation.…”

The urgent demand for high‐energy‐density storage systems evokes the research upsurge on the alkali metal batteries with high theoretical capacities. However, the utilization of alkali metal anodes, including Li, Na, and K, is significantly hindered by notorious dendrite growth, undesirable corrosion, and unstable solid electrolyte interface. In order to resolve these issues, the carbon materials for the rational design of current collector/host that can regulate the plating/stripping behavior of alkali metal have been exploited. These carbon‐based current collectors/hosts are featured with many pivotal advantages, including mechanical integrity to accommodate the volume change, superior electronic/ionic conductivity, large available surface area, and rich functionalization chemistries to increase the affinity to alkali metal. In this review, the recent progress on various dimensional carbon‐based current collectors/hosts with different chemical components in stabilizing the alkali metal anodes through the regulation of initial deposition and subsequent growth behavior during plating/stripping process is provided. The nanostructured carbon scaffolds with self‐affinity to alkali metals, as well as the carbon frameworks with internal/external affinitive sites to alkali metals, catalogued by various dimensions, are discussed in this review. Therefore, these appealing strategies based on the carbon‐based current collectors/hosts can provide a paradigm for the realization of high‐energy‐density alkali metal batteries.

“…[19,20] PHCSs are also an ideal model system for operando TEM experiments for studying specific details of electrochemical processes since they do not require additional TEM sample preparation, provide necessary electron-beam transparency, and their structure/chemical composition can be easily adapted for further optimization. [21] Several possible sodium storage mechanisms, such as insertion, adsorption, the combination of adsorption and insertion, and the multistage mechanism, have been proposed in the literature. [22][23][24][25][26] For instance, Dahn et al suggested that sodium follows the insertion-adsorption mechanism during storage in hard carbons.…”

Carbonaceous materials are promising sodium‐ion battery anodes. Improving their performance requires a detailed understanding of the ion transport in these materials, some important aspects of which are still under debate. In this work, nitrogen‐doped porous hollow carbon spheres (N‐PHCSs) are employed as a model system for operando analysis of sodium storage behavior in a commercial liquid electrolyte at the nanoscale. By combining the ex situ characterization at different states of charge with operando transmission electron microscopy experiments, it is found that a solvated ionic layer forms on the surface of N‐PHCSs at the beginning of sodiation, followed by the irreversible shell expansion due to the solid‐electrolyte interphase (SEI) formation and subsequent storage of Na(0) within the porous carbon shell. This shows that binding between Na(0) and C creates a Schottky junction making Na deposition inside the spheres more energetically favorable at low current densities. During sodiation, the SEI fills the gap between N‐PHCSs, binding spheres together and facilitating the sodium ions' transport toward the current collector and subsequent plating underneath the electrode. The N‐PHCSs layer acts as a protective layer between the electrolyte and the current collector, suppressing the possible growth of dendrites at the anode.
