Summary: The research on lithium-ion hybrid capacitors (LIHCs) focuses on improving the specific capacity of the cathode to solve the capacity imbalance issue in LIHCs. The introduction of anthraquinone (AQ) as a pseudocapacitive material in the cathode, supported by polypyrrolederived carbon tube (CT) with ultrahigh surface area, enhances the initial discharge specific capacity and capacity retention of LIHCs. A CT//AQ/CT0.25 LIHC device assembled with the optimized cathode and a CT anode delivers remarkable specific energy and cyclic stability.

Summary: Developing liquid electrolytes with higher kinetics and enhanced interphase stability is crucial for improving lithium battery performance. This study demonstrates that introducing multiple salts to form a high-entropy solution can improve solubility and stabilize electrode-electrolyte interphases. The high-entropy electrolytes significantly enhance cycling and rate performance, extending the cycle life of lithium batteries and achieving more than 1000 charge-discharge cycles for commercial batteries. These improvements are attributed to the unique features of the solvation structure in high-entropy electrolytes, which result in improved lithium-ion kinetics and stabilized interphases.

Summary: This study demonstrates that vacancy engineering is an effective strategy to enhance the permselectivity of 2D nanofluidic membranes for high-efficiency osmotic energy generation. By creating phosphorus vacancies on NbOPO4 (NbP) nanosheets, the negative surface charge is remarkably increased, resulting in fast transmembrane ion migration and high ionic selectivity. When applied in a natural river water|seawater osmotic power generator, the macroscopic-scale V-NbP membrane delivers a record-high power density of 10.7 W m(-2), surpassing the commercial benchmark of 5.0 W m(-2).

Summary: By designing an aqueous electrolyte with a weakly solvating effect, a durable anion-derived solid electrolyte interface (SEI) with high ion conduction properties is constructed, which significantly restrains dendrite formation and adverse reactions on the Zn anode surface, leading to high reversibility of deposition/stripping, ultra-long lifespan over 5000 h, and exceptional cumulative capacity. The formation mechanism of SEI and the composition distribution of anion-derived inorganic-rich SEI are clarified in detail. Furthermore, the Zn//Prussian blue analogue (PBA) full battery exhibits a high voltage platform of 2.1 V and delivers 99.3% capacity retention after 5000 cycles, benefiting from the synergy of the elaborate SEI and regulated electrolyte environment.

Summary: The power density and lifespan of Zn metal batteries are limited by uncontrolled zinc electrodeposition and side reactions. This study demonstrates the multi-level interface adjustment effect using low-concentration redox-electrolyte (0.2 m KI) additives. Iodide ions adsorbed on the zinc surface suppress water-induced side reactions, enhance zinc deposition kinetics, and guide the deposition of zinc ions. As a result, the Zn||Zn symmetric cell shows excellent cycling stability (>3000 h at 1 mA cm(-2), 1 mAh cm(-2)) with uniform deposition and fast reaction kinetics. The Zn||AC cell, combined with an activated carbon cathode, also demonstrates high-capacity retention (81.64% after 2000 cycles at 4 A g(-1)).

Summary: Aqueous iron batteries have the potential for large-scale energy storage due to their safety and low cost. However, their long-term cycling stability is inadequate. In this study, cross-linked polyaniline (C-PANI) is proposed as a positive electrode active material to improve the electronical conductivity and electrochemical stability. The C-PANI, when combined with Fe metal negative electrode and Fe(TOF)(2) electrolyte, shows good specific capacity and discharge voltage after a high number of cycles. Mechanistic studies suggest that the bonding of Fe2+ ions to TOF- anions plays a role in the storage of charge.

Summary: We accelerate the kinetics of acid oxygen reduction reaction (ORR) by using a bi-functional ligand-assisted strategy to pre-control the distance of hetero-metal atoms. The synthesized Fe-Zn diatomic pairs on carbon substrates show outstanding ORR performance with an ultrahigh half-wave potential of 0.86 V vs. RHE in acid electrolyte. The specific distance range of around 3 angstrom between Fe-Zn diatomic pairs is the key to their ultrahigh activity, averaging the interaction between hetero-diatomic active sites and oxygen molecules.
