1 · What the graph read from it

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.

2 · The registry

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

Polybenzimidazole (PBI) is a promising separator for lithium-ion batteries (LIBs) owing to its excellent thermal/chemical stability and mechanical strength, but its application is limited by poor solubility and processability. Herein, a novel ether-functionalized PBI was synthesized, and three-layer composite separators (PBIPHPE) were fabricated by electrospinning PBI/PVDF-HFP blends onto polyethylene (PE) substrate. The PBIPHPE separator exhibits high porosity (73.1%), superior electrolyte uptake (211.2%), and excellent ionic conductivity (1.125 mS/cm), with no dimensional change after thermal treatment at 150 °C for 0.5 h. Lithium-ion batteries assembled with PBIPHPE deliver an initial specific capacity of 157.7 mAh/g, retain 86.0% capacity after 400 cycles at 2 C, and show only 15.7% capacity decay from 0.2 C to 5 C. Molecular dynamics simulations of the composite separator-electrolyte system were performed to reveal Li
