Surface‐functionalized SiNPs are synthesized by a simple and scalable hydrosilylation method using 4‐vinylpyridine (4VP), 1‐vinyl‐2‐pyrrolidinone (1V2P), and acrylic acid (AA). The Si‐4VP‐based Li‐ion cells achieved a promising long life of 300 cycles, retaining 60% of the initial capacity (2375 mAh g−1).

The fossil‐based substrates of a printed supercapacitor containing liquid electrolytes can only be replaced with biopolymers if they have adequate permeabilities. This article studies three biopolymers based on their processability, printability, and barrier properties to find a more sustainable substrate option.
