Low-Cost Silicon from Natural Sand with Tunable Oxygen Content and Its Effects on the Electrochemical Properties of Lithium-Ion Battery Anodes.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Silicon (Si) is recognized as a promising anode material for lithium-ion batteries (LIBs). However, the significant volume expansion during lithiation poses a make-or-break challenge for the commercial adoption of silicon as an anode. The solutions to mitigate the challenge often depend on processes that can increase costs for the LIB. Here, we demonstrate a magnesiothermic reduction process that uses low-cost natural sand as the raw material to produce battery-grade silicon with a high conversion rate of ∼98%. The magnesiothermic reduction process can produce Si products with varying oxygen content depending on certain process parameters, including the Mg:Si molar ratios and temperature. Therefore, we also investigated the effect of the oxygen content on electrochemical performance as an anode. The results show that the initial discharge capacity and initial Coulombic efficiency (ICE) decrease linearly with increasing oxygen content. In contrast, the capacity retention and the lithium-ion diffusion coefficient (
