Sigma-Aldrich 1,3,2-二噁唑噻吩-2,2-二氧化物，≥99%，无水，电池级

产品概述

硫酸乙二酯（DTD）是一种极性环状硫酸酯。它是一种白色粉末，可溶于电池应用中使用的许多极性有机溶剂，包括碳酸盐。我们的电池级硫酸乙二酯具有高纯度、低微量水含量和低微量酸含量的特点，可避免与阳极发生不必要的化学反应，提高电池的容量、安全性和寿命。

应用领域

Ethylene sulfate has a range of industrial applications. Our anhydrous battery grade ethylene sulfate is primarily used as an electrolyte additive to extend the lifetime of lithium-ion batteries and sodium-ion batteries.[,] Ethylene sulfate helps to improve the formation of a stable solid-electrolyte interphase (SEI) on the surface of the anode material, which can prevent reaction between the anode and the electrolyte, leading to better battery lifespan and more stable impedance across the interphase.[] DTD is often used in conjunction with other additives. One of the best-performing electrolyte formulations for graphite cells is a 1.0 M LiPF6 in a carbonate blend with 1% DTD and 2%VC.[,]
