Charge-engineered cellulose nanofibril binders for PFAS-free, high-loading lithium battery positive electrodes.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The increasing demand for sustainable high-energy lithium-ion batteries has heightened concerns over the environmental and health impacts of per- and polyfluoroalkyl substances, used in current battery components. In particular, polyvinylidene fluoride, a synthetic resin used as the dominant electrode binder, relies on fluorinated chemicals and toxic solvents such as N-methyl-2-pyrrolidone, while also suffering from limited structural integrity under high-mass-loading conditions. Here, we show that a PFAS- and N-methyl-2-pyrrolidone-free binder based on charge-engineered cellulose nanofibrils derived from natural wood offers a renewable and sustainable alternative to polyvinylidene fluoride. The charge-engineered cellulose nanofibril binder, leveraging its cationic functional groups, promotes particle dispersion in the slurry through electrostatic repulsion and subsequently forms strong hydrogen bonds with electrode components after drying, reinforcing structural integrity. Additionally, its nanofibrous architecture forms robust, interconnected networks that facilitate electrolyte infiltration and ion transport. When implemented in LiNi
