High-Voltage Lithium Batteries Enabled by Facile In Situ Fabrication of Monophasic Cellulose-Based Single-Ion Conductors.

The growing demand for high-energy-density, safe, and sustainable lithium-ion batteries (LIBs) necessitates the development of innovative electrolytes. Herein, we present a facile in situ preparation strategy for fabricating a high-performance single-ion conductor (SC). This SC is based on hydroxypropyl cellulose (HPC) integrated with polyethylene glycol diacrylate cross-linker, in combination with sodium styrene sulfonate (NaSS) as a functional monomer.

Mechanically Robust Cellulose-Based Piezoelectric Elastomer Formed by Slidable Polyrotaxane Cross-Linker.

Cellulose has great potential in the field of piezoelectricity owing to its high crystallinity; however, it exhibits low processability and poor mechanical robustness. In this study, to enhance the applicability of cellulose-based piezoelectric materials, a robust cellulose-based piezoelectric elastomer with excellent piezoelectric properties was developed by cross-linking cellulose with polyrotaxane (PR). The effects of cross-linking on the mechanical properties and crystalline structures of the resulting elastomers were investigated.

Self-Healable Conductive Hydrogels with High Stretchability and Ultralow Hysteresis for Soft Electronics.

Stretchable sensors based on conductive hydrogels have attracted considerable attention for wearable electronics. However, their practical applications have been limited by the low sensitivity, high hysteresis, and long response times of the hydrogels. In this study, we developed high-performance poly(vinyl alcohol) (PVA)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) based hydrogels post-treated with NaCl, which showed excellent mechanical properties, fast electrical response, and ultralow hysteresis properties.
