Interfacially stable and high-safety lithium batteries enabled by porosity engineering toward cellulose separators

Jingren Gou et al.

Summary: Nanocellulose is a promising alternative to plastic-based materials in energy storage devices due to its biodegradability, heat resistance, mechanical strength, and wettability. However, the compact microstructure of nano-cellulose separators hinders electrolyte uptake and Li+ migration. A porosity engineering method combining filtration and templating is proposed to fabricate cellulose separators with tunable pore size and porosity. Experimental and numerical results show that nanopores promote uniform evolution of the electrode-electrolyte interface (EEI), and separators with proper porosity retain high ionic conductivity and mechanical strength. The nanoporous separator with 61.5% porosity is considered suitable for lithium-ion batteries, showing stable cycling and high capacity retention.

Design of polyimide-based separators for effective suppression of self-discharge in non-aqueous electrical double layer capacitors

Hao-Yu Ku et al.

Summary: This study focuses on alleviating water-induced self-discharge in non-aqueous EDLCs by using a polyimide (PI) separator coated with polyurethane-poly(acrylic acid) (PUPAA) copolymer (PI@PUPAA). The copolymer effectively absorbs trace water in the electrolyte, leading to a significant reduction in self-discharge of the EDLC cells. The introduction of Al2O3 nanoparticles into PI to form a composite separator (PI + Al2O3@PUPAA) improves the electrochemical responses of EDLCs, making it a promising separator for decelerating the self-discharge process.
