Summary: The use of sodium lignosulfonate as a binder in hard carbon anodes for sodium-ion batteries shows comparable or better performance compared to other binders, with high capacity retention and stability. When using 1 M NaPF6 in propylene carbonate or ethylene carbonate:diethyl carbonate electrolytes, the performance is further improved, particularly when including styrene-butadiene rubber as a co-binder. X-ray photoelectron spectroscopy analysis shows similar solid electrolyte interphase compositions for lignosulfonate and carboxymethyl cellulose binders after initial sodium insertion, but differences in surface layer composition and thickness are observed after subsequent cycling.

Summary: Organic redox compounds, like copper-tetracyanoquinodimethane (CuTCNQ), show promise as cathode materials for aqueous zinc-ion batteries due to their low cost, environmental friendliness, and multiple-electron-transfer reactions. Through electrochemical activation, electrolyte optimization, and adoption of a graphene-based separator, CuTCNQ-based batteries demonstrate improved rate performance, cycling stability, and anti-self-discharge properties. The impressive electrochemical performance of CuTCNQ in aqueous electrolytes is attributed to the strong electron acceptation ability of the cyano groups in CuTCNQ and the graphene-modified separator that prevents CuTCNQ dissolution and shuttle effect.

Summary: In this study, a Ni-Cu salts/poly(vinyl alcohol) based organohydrogel electrolyte with excellent transparency, ionic conductivity, and mechanical properties was developed. The high viscosity of the electrolyte enabled the electrodeposition of a homogeneous Ni-Cu alloy film with a surface roughness of around 11.2 nm, which retained its black color for over 350 minutes with only a 5% increase in transmittance. The solid-state rigid electrochromic device exhibited outstanding optical contrast and cycling stability. A flexible electrochromic device was also fabricated using the organohydrogel electrolyte and annealed ITO-coated PEN films, showing good mechanical flexibility and optical contrast.

Summary: Through the nanoconfinement strategy and electrospinning technique, ultrafine carbon nanofiber-supported Co9S8/WS2@C particles are obtained, leading to exceptional rate performance and stable structural stability. The introduction of β-cyclodextrin during the synthesis process plays a crucial role in the confinement of nanoparticles and the generation of porous structure. The large surface area, ultrafine particles, and rich heterointerfaces in Co9S8/WS2@C@CNF contribute to reducing the diffusion length of Na+ and promoting reaction kinetics. The electrode also demonstrates an ultra-long lifespan in full-cell Na-ion batteries.

Summary: The fast development of wearable electronic systems requires a sustainable energy source. Piezoelectric polymer films are a perfect candidate for fabricating nanogenerators, but most of their applications are limited to the pressing mode energy harvesting. In this work, an auxetic structure is 3D printed on a polymer film-based PENG, enabling the bending deformation of the PENG to be transformed into controlled in-plane stretching deformation, increasing the bending output voltage by 8.3 times. The auxetic structure-assisted PENG is also demonstrated as a sensor for bending angle and motion monitoring.

Summary: By adding a soft, stretchable, transparent, and solid-state poly(ionic liquid) (PIL) as a compliant filler, the actuation performance of dielectric elastomer actuators (DEAs) can be improved. The PIL filler provides high dielectric constant and low Young's modulus, increasing the strain and bending angle of the DEAs. Notably, the PIL filler also eliminates filler leakage problems and enables the DEAs to have recoverability. The solid-state PIL filler can be used for soft robotics, interactive lighting, or wearables.
