中文名:氟代碳酸乙烯酯,英文名:4-Fluoro-1,3-dioxolan-2-one,CAS:114435-02-8,化学式:C3H3FO3,分子量:106.05,密度:1.454,熔点:18-23 °C,沸点:212℃,闪点:>102° (216°F),水溶性:Slightly miscible with water.,蒸汽压:51Pa at 25℃,折射率:1.3960 to 1.4000,MSDS.

氟代碳酸乙烯酯（fec）是锂电池电解液添加剂的重要组分之一，其工业制备方法主要为卤素交换法，即氯代碳酸乙烯酯（cec）与氟化钾（kf）通过取代反应制备fec。

2023年8月1日 · For the sulfone-based electrolytes containing FEC additives, F5 - F7, the addition of FEC can further increase the ionic conductivity of F4 by decreasing the viscosity and increasing the dissolution of lithium salts due to its high dielectric constant (ɛ = 110).

氟代碳酸乙烯酯是一种化学物质，主要的锂离子电池电解液添加剂，形成SEI膜的性能更好，形成紧密结构层但又不增加阻抗，能阻止电解液进一步分解，提高电解液的低温性能。

2023年1月13日 · FEC（前向纠错码）是用于控制数据传输中误码率的技术，尤其在高速光通信中，能检测和纠正错误，提高传输质量和距离。 Reed-Solomon码是常用的FEC类型，适用于不同类型的光模块，如25G和100G模块。 FEC有块码和卷积码两种形式，能有效对抗噪声和光色散导致的信号退化，但也引入了延迟和额外开销。 在实施FEC时，需确保链路两端匹配的FEC类型。 光模块 正在向着高速率、远距离方向发展。 与100G以太网及更高速率的高速通信时，可能会出 …

氟代碳酸乙烯酯（114435-02-8）是主要的锂离子电池电解液添加剂，形成SEI膜的性能更好，形成紧密结构层但又不增加阻抗，能阻止电解液进一步分解，提高电解液的低温性能和提高锂电池的循环寿命。 模块1. 化学品. 仅用于研发。 不作为药品、家庭或其它用途。 模块2. 危险性概述. H302吞咽有害。 H315造成皮肤刺激。 H317可能导致皮肤过敏反应。 H319造成严重眼刺激。 P261避免吸入粉尘/烟/气体/烟雾/蒸气/喷雾. P264操作后彻底清洁皮肤。 P270使用本产品时 …
