Sigma-Aldrich Zinc(II) Acetate，无水，电池级，≥99.9%痕量金属

产品概述

乙酸锌（II），一种多用途的白色固体粉末，是合成基于锌材料的合适前体，包括金属有机框架（MOFs）、氧化锌纳米颗粒和先进纳米复合材料。它在制造高性能锌离子电池电解质中也至关重要。我们提供无水、电池级乙酸锌（II）（≥99.9% 杂质金属基），总杂质金属含量低于1000 ppm。它具有低杂质金属含量、最少的阴离子杂质（硫酸盐、氯化物、硝酸盐）和超低水分含量，确保在医药、半导体、电池和催化行业中提供优越的纯度和可靠性。

应用领域

Zinc(II) acetate emerges as a vital precursor in zinc-ion battery (ZIB) research, enabling the synthesis of high-performance ZnO-based cathodes, anodes, and protective coatings through controlled thermal decomposition. Its versatility shines in in situ formation of ZnO cathodes for high-rate aqueous Zn-I₂ batteries, achieving exceptional stability (>500 cycles at 5 A g⁻¹) and energy densities approaching 200 Wh kg⁻¹.Similarly, it facilitates ZnMn₂O₄ spinel cathodes that deliver 150 mAh g⁻¹ at 0.2C with 90% capacity retention over 200 cycles in mild aqueous electrolytes, ideal for safe, scalable grid storage and beyond.[,] Our high-purity Zn acetate (≥99.9% trace metals basis) ensures minimal impurities for scalable ZIBs targeting grid storage, outperforming Li-ion in cost/safety. Our high-purity Zn(II) acetate excels as a precursor for the synthesis of nanocrystalline ZnO electron injection layers (EILs) in advanced solution-processed devices, powering quantum dot LEDs (QLEDs), perovskite LEDs, QD laser diodes, QD photodiodes, and high-efficiency solar cells with superior charge transport and stability.[,]
