Summary: Among energy storage devices, lithium-ion capacitors (LICs) stand out due to their high energy densities and power densities. However, the mismatch in storage mechanisms between the positive and negative materials limits the performance of LICs. In this study, a Sn-based heterostructure@MXene anode material was synthesized to achieve excellent rate performance and increased lithium storage capacity, leading to a better match with the cathode. The hybrid electrode demonstrated remarkable rate performance and cycle stability, reducing the kinetic gap with capacitor-type cathodes. Assembled LICs based on this hybrid anode and nitrogen-doped activated carbon cathode exhibited high power/energy density and long cycling life.

Summary: Sodium-ion capacitors (SICs) are environmentally friendly and high-efficiency energy storage devices that combine the benefits of batteries and supercapacitors, offering potentially high energy/power densities and long lifespan. A heterostructured Fe/FeSe2/Fe3Se4 nanocomposite was prepared through chemical vapor deposition (CVD) as the anode for SICs, demonstrating better sodium ion storage performances compared to pure FeSe2 and FeSe2/Fe3Se4. The excellent performance of Fe/FeSe2/Fe3Se4 nanocomposite can be attributed to the synergistic effect of heterointerface engineered components, enabling high capacity and accelerated electron and charge transfer behavior. The heterointerface also facilitates fast sodium ion transport and retards structural variation during cycling, leading to high-performance SICs.

Summary: In this study, highly sensitive surface-enhanced Raman spectroscopy (SERS) was used to reveal the spontaneous desorption behavior of insoluble products of lithium peroxide (Li2O2) from the electrode surface. The electrochemical oxygen reduction reaction (ORR) mechanism at the electrode/Li2O2 interface was elucidated based on a dynamic equilibrium between the generation and desorption of Li2O2. The desorption of adsorbed Li2O2 species (Li2O2*) is crucial in maintaining the stability and discharge plateau of the galvanostatic ORR process.

Summary: Gel polymer electrolytes (GPEs) are used as alternatives to liquid electrolytes in lithium-metal batteries (LMBs). Adding diluent 1,1,2,2-tetrafluoroethyl 2,2,3,3-tetrafluoropropyl ether (TTE) to regulate the electrolyte structure improves the electrochemical stability and ion transport properties of GPEs. The addition of TTE enhances ion association and forms a robust and low-impedance solid electrolyte interface (SEI) on the anode surface. This study provides an effective approach for controlling solvation structures in GPEs, which can advance the design of GPE-based LMBs in the future.
