Eco-friendly approach for the effective leaching of valuable metals (Ni, Co, Mn) from spent lithium-ion batteries employing natural reductants.
Article in RSC advances, 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 widespread utilization of lithium-ion batteries (LIBs) in energy storage systems has led to an accumulation of discarded LIBs. Recycling has been implemented as a novel approach to alleviate the detrimental impacts of battery waste and facilitate the recovery of precious metals. This innovative method utilizes an eco-friendly hydrometallurgical process for metal leaching, employing biodegradable mixed organic acids, specifically citric acid (C.A.) and tartaric acid (T.A.), alongside sugarcane bagasse, an agricultural byproduct. These experiments indicate that around 84% of Ni, 88% of Co, 95% of Li, and 93% of Mn were extracted under optimal circumstances of 1.5 : 1.5 mol L
