“…Voltage curve under continuous charging in symmetrical cell (Figure S11, Supporting Information) shows severe fluctuation in bare ZnSO 4 electrolyte, in contrast, a high Zn extraction rate is obtained in ZnSO 4 +Arg electrolyte which indicates the reversibility of electrode is greatly improved. [46][47][48] The results from above electrochemical tests strongly prove the effectiveness of Arg additive, which can be ascribed to the formation of stable and self-adaptive interface layer due to the strong electrostatic adsorption of Arg molecules. Such self-adaptive zinc-electrolyte interface can be constructed by other positively charged amino acid such as lysine (Lys) and similar promotion effect is demonstrated with long cycle life and high CE in symmetric cells (Figure S12, Supporting Information), demonstrating the universal applicability of the interface charge engineering strategy.…”

Despite the impressive merits of low-cost and high-safety electrochemical energy storage for aqueous zinc ion batteries, researchers have long struggled against the unresolved issues of dendrite growth and the side reactions of zinc metal anodes. Herein, a new strategy of zinc-electrolyte interface charge engineering induced by amino acid additives is demonstrated for highly reversible zinc plating/stripping. Through electrostatic preferential absorption of positively charged arginine molecules on the surface of the zinc metal anode, a self-adaptive zinc-electrolyte interface is established for the inhibition of water adsorption/hydrogen evolution and the guidance of uniform zinc deposition. Consequently, an ultra-long stable cycling up to 2200 h at a high current density of 5 mA cm −2 is achieved under an areal capacity of 4 mAh cm −2 . Even cycled at an ultra-high current density of 10 mA cm −2 , 900 h-long stable cycling is still demonstrated, demonstrating the reliable self-adaptive feature of the zinc-electrolyte interface. This work provides a new perspective of interface charge engineering in realizing highly reversible bulk zinc anode that can prompt its practical application in aqueous rechargeable zinc batteries.

“…Figure 2b compares the cycling stability of our Na 2 S/V layer with those of previously reported protective layers. [ 39,44–52 ] Clearly, the cycling stability of our Na 2 S/V/Na electrode is superior. Even at 2 mA cm −1 , the Na 2 S/V/Na symmetric cell displayed a long cycle life of over 400 h (Figure S9, Supporting Information).…”

Metallic Na (K) are considered a promising anode materials for Na‐metal and K‐metal batteries because of their high theoretical capacity, low electrode potential, and abundant resources. However, the uncontrolled growth of Na (K) dendrites severely damages the stability of the electrode/electrolyte interface, resulting in battery failure. Herein, a heterogeneous interface layer consisting of metal vanadium nanoparticles and sodium sulfide (potassium sulfide) is introduced on the surface of a Na (K) foil (i.e., Na2S/V/Na or K2S/V/K). Experimental studies and theoretical calculations indicate that a heterogeneous Na2S/V (K2S/V) protective layer can effectively improve Na (K)‐ion adsorption and diffusion kinetics, inhibiting the growth of Na (K) dendrites during Na (K) plating/stripping. Based on the novel design of the heterogeneous layer, the symmetric Na2S/V/Na cell displays a long lifespan of over 1000 h in a carbonate‐based electrolyte, and the K2S/V/K electrode can operate for over 1300 h at 0.5 mA cm–2 with a capacity of 0.5 mAh cm–2. Moreover, the Na full cell (Na3V2(PO4)3||Na2S/V/Na) exhibits a high energy density of 375 Wh kg–1 and a high power density of 23.5 kW kg–1. The achievements support the development of heterogeneous protective layers for other high‐energy‐density metal batteries.

Seeking an optimal catalyst to accelerate conversion reaction kinetics of room‐temperature sodium–sulfur (RT Na–S) batteries is crucial for improving their electrochemical performance and promoting the practical applications. Herein, theoretical calculations of interfacial interactions of catalysts and polysulfides in terms of the surface adsorption state, interfacial ions migration, and electronic concentration around the Fermi level are systematically proposed as guiding principles of catalyst selection for RT Na–S batteries. As a case, MoN catalyst is accurately selected from transition metal nitrides with different d orbital electrons, and for experiment, it is introduced into the carbon nanofibers as a dual‐functioning host (MoN@CNFs). The MoN@CNFs can effectively anchor polysulfides and accelerate their conversion reaction. In addition, for the sodium anode, the MoN@CNFs can also induce uniform deposition of Na and inhibit dendrite growth, which are supported by in situ characterizations and finite element simulation technique. As a result, the as‐prepared RT Na–S battery displays high reversible capacity of 990 mAh g–1 at 0.2 A g–1 after 100 cycles and long lifespan over 1500 cycles at 2 A g–1. Even with high S loading of 5 mg cm–2, the RT Na–S battery still exhibits a high areal capacity of 2.5 mAh cm–2.
