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

Aqueous zinc-ion batteries (AZIBs) hold great promise for safe and low-cost energy storage, yet their practical application is seriously hindered by the hydrogen evolution reaction (HER), uncontrolled dendrite growth, and inert byproduct (Zn4SO4(OH)6·xH2O) deposition on the Zn anode. In this work, sarcosine (Sar) was adopted as a multifunctional bipolar electrolyte additive, and first-principles calculations combined with electrochemical tests and interfacial characterizations were performed to reveal its adsorption-dominated interfacial stabilization mechanism. Sar strongly adsorbs on the Zn surface to homogenize Zn2+ flux, regulate the electric field distribution, and reconfigure the interfacial environment. Meanwhile, Sar forms strong intermolecular hydrogen bonds with water molecules via its amino and carboxyl groups, reducing free water activity and suppressing HER. First-principles calculations verify the favorable adsorption configuration and high adsorption energy of Sar on the Zn surface. As a result, the Zn||Zn symmetric cell delivers ultra-long cycling stability over 2100 h at 1 mA cm-2, and the Zn||Cu half-cell exhibits a high average Coulombic efficiency of 99.7%. The full cell with ZnI@CNT-AC cathode maintains excellent capacity retention after 3000 cycles. This work provides a simple, green, and low-cost strategy for stabilizing Zn anodes toward practical aqueous zinc-ion batteries.
