Per and Polyfluoroalkyl Substances‐Free Poly(ionic liquid) Reinforced with Cellulose Nanofibrils as Sustainable Electrolyte for High‐Voltage Solid‐State Lithium Batteries

open access: yesBatteries &Supercaps, Volume 9, Issue 4, April 2026.
Lithium metal batteries offer high energy density, but require safer, more stable, and sustainable electrolytes. Per and polyfluoroalkyl substances‐free polymer electrolytes based on poly(diallyldimethylammonium) bis(fluorosulfonyl)imide, N‐methyl‐N‐propylpyrrolidinium bis(fluorosulfonyl)imide, and lithium bis(fluorosulfonyl)imide, reinforced with ...

The Influence of the Electrolyte on Lithium Transport Through the DAAQ‐TFP‐COF Structure: A Molecular Dynamics Study

open access: yesBattery Energy, Volume 5, Issue 1, January 2026.
We study the interaction between a DAAQ‐TFP‐COF based electrode and two differente electrolytes, LiTFSI@TEGDME and LiPF6@EC/DEC, with classical molecular dynamics. We adress the correlation between structural properties and ion transport mechanisms. We stress the importance of the choice of the electrolyte in battery design.
