“…The presence of 60 % DCE slightly shortened the distances of Li−O (SOCl 2 ) and Li−Al (AlCl 4 − ) and resulted in a new Li−C (DCE) peak at 2.9 Å (Figure 4d). This indicated that DCE molecules were involved in the first layer of the solvation structure that encircled the Li ions and SOCl 2 molecules, [37,38] thus serving as an effective diluent that effectively suppressed the corrosivity of the SOCl 2 ‐based electrolyte (Figure S14).…”

Chlorine (Cl)‐based batteries such as Li/Cl2 batteries are recognized as promising candidates for energy storage with low cost and high performance. However, the current use of Li metal anodes in Cl‐based batteries has raised serious concerns regarding safety, cost, and production complexity. More importantly, the well‐documented parasitic reactions between Li metal and Cl‐based electrolytes require a large excess of Li metal, which inevitably sacrifices the electrochemical performance of the full cell. Therefore, it is crucial but challenging to establish new anode chemistry, particularly with electrochemical reversibility, for Cl‐based batteries. Here we show, for the first time, reversible Si redox in Cl‐based batteries through efficient electrolyte dilution and anode/electrolyte interface passivation using 1,2‐dichloroethane and cyclized polyacrylonitrile as key mediators. Our Si anode chemistry enables significantly increased cycling stability and shelf lives compared with conventional Li metal anodes. It also avoids the use of a large excess of anode materials, thus enabling the first rechargeable Cl2 full battery with remarkable energy and power densities of 809 Wh kg−1 and 4,277 W kg−1, respectively. The Si anode chemistry affords fast kinetics with remarkable rate capability and low‐temperature electrochemical performance, indicating its great potential in practical applications.

“…LiNO 3 has been proven as a good remedy for non‐aqueous lithium metal anodes. [ 45–47 ] However, the insolubilization has pushed the researchers to leave no stone unturned to introduce LiNO 3 in carbonate solvents, [ 48 ] such as encapsulated in porous polymer gel [ 49 ] and introducing anion receptors. [ 50 ] We aim, to be inspired, to add LiNO 3 in HD‐OTf to further bundle water molecules in consideration of the insolubilization in DMC, labeled as HD‐OTf/Li (Table S1, Supporting Information).…”

Aqueous zinc ion batteries (ZIBs) are troubled by the severe Zn dendrite growth and side reactions, manifesting as low coulombic efficiency and poor cyclic stability. Electrolyte engineering is regarded as an efficient method to improve Zn metal reversibility. Herein, a distinctive electrolyte regulation strategy is demonstrated for long‐lasting ZIBs through the construction of competitive solvation structures. In the composite aqueous system, the insoluble LiNO3 in dimethyl carbonate (DMC) is introduced to outwit active water dissociation from Zn2+ coordination environment, and the organic/anion‐enriched solvation structure enables the formation of a stable interface to effectively restrain adverse reactions. Distinctly, the Zn metal anode exhibits inhibited dendrite growth with high reversibility of plating/stripping processes over 1600 h with an exceptional cumulative capacity over 16 Ah cm−2, an ultra‐long lifespan over high‐temperature (50 °C), and high discharge of depth (65%). Furthermore, the Zn || V2O5 full battery can operate stably over 1000 cycles at 1 A g−1. This work points a direction to effectively solve the major challenges of ZIBs through the collaborative construction of a regulated electrolyte environment and interfacial chemistry.

To meet the demand for high‐energy‐density batteries, alloy‐type and conversion‐type anode materials have attracted growing attention due to their high specific capacity. However, the huge irreversible lithium loss during initial cycling significantly reduces the energy density of the full cell, which limits their practical applications. Fortunately, various anode prelithiation techniques have been developed to compensate for the initial lithium loss. At the same time, the cathode prelithiation has been proposed and demonstrated remarkable enhancement in the electrochemical performance, along with excellent scalability and compatibility with the existing battery production processes. Here, recent advances are reviewed in the prelithiation of both anodes and cathodes, and the key challenges are discussed in front of their practical applications. It is aimed to provide better recommendations and assistance for its large‐scale practical applications.
