🔋 Beyond Phase Selectivity in Conversion Copper Selenides Cathode through Activated Anionic Redox
📝 فعالسازی ردوکس آنیونی در کاتد سلنید مس، ظرفیت CuSe را از ۴ به ۴۱۳ mAh g–1 افزایش داد و باتری روی با عمر ۴۰۰۰ چرخه را ممکن ساخت.

💡 Novelty & Significance:
This work shows that activating selenium anionic redox overcomes phase-selectivity limits in copper selenide cathodes, converting zincophobic CuSe into a high-capacity electrode (4 to 413 mAh g⁻¹, doubled voltage, 4000-cycle life). It enables the whole CuySe family as stable zinc-battery cathodes and generalizes to other nucleophilic additives, revitalizing a dormant material class.
