摘要

Abstract > Increasing the capacity of Li‐rich layered oxide (LMNC) cathode material for high‐energy density lithium‐ion batteries relies on the increase of charge cut‐off voltage toward 5 V, under the utilization of anodically stable electrolyte component. The utilization of di‐(2,2,2 trifluoroethyl)carbonate (DFDEC)‐containing electrolyte permits significant improvement of anodic stability, cathode–electrolyte interface, and cycling stability of LMNC cathode, with respect to conventional electrolyte. In the present study, the limit of anodic stability of DFDEC under charging to 5.5 V versus Li is explored, and the interfacial processes of DFDEC‐derived surface protection mechanism are investigated, utilizing charge cut‐off voltage‐dependent surface and structural analyses. The oxidative decomposition of DFDEC is found to begin at 4.7 V, producing metal fluorides and CF‐containing organic compounds as the earliest surface species, passivating the cathode surface and reducing metal dissolution, structural transformation, and cathode degradation. The tolerable limit of charge cut‐off voltage of a model electrolyte of 0.1 <sc>m</sc> LiPF <sub>6</sub> /DFDEC is determined to be 5.0 V, to which the cathode outperforms conventional electrolyte, delivering discharge capacities of 261–225 mAhg ?1 with the capacity retention of 86% at the 50th cycle. The data give an insight into the principles of electrolyte design and high‐voltage cathode–electrolyte interfacial stabilization toward advanced 5 V lithium‐ion batteries. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> > 在利用阳极稳定的电解质组分的利用率下，增加高能量密度锂离子电池的富含量锂层（LMNC）阴极材料的容量依赖于朝向5V的电荷截止电压的增加。二 - （2,2,2三氟乙基）碳酸酯（DFDEC）电解质的利用允许显着提高LMNC阴极的阳极稳定性，阴极电解质界面和循环稳定性相对于常规电解质。在本研究中，探索了DFDEC的阳极稳定性的极限，进行了5.5V与LI与锂，研究了DFDEC推导的表面保护机构的界面过程，利用电荷切断电压依赖性表面和结构分析。发现DFDEC的氧化分解在4.7V开始，生产金属氟化物和含CF的有机化合物作为最早的表面物质，钝化阴极表面并降低金属溶解，结构转变和阴极降解。 0.1的模型电解质的电荷截止电压的可容忍极限 <sc> m </ sc> Lipf. <sub> 6 </ sub> / dfdec确定为5.0V，阴极优于传统电解质，输送261-225 mahg的放电容量？1 </ sup> 在第50个周期的容量保持86％。该数据深入了解电解质设计和高压阴极 - 电解质界面稳定朝向前进的5V锂离子电池的原理。 </ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-18063/'>《Advanced materials interfaces》</a> <b style="margin: 0 2px;">|</b><span>2017年第24期</span><b style="margin: 0 2px;">|</b><span>共10页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Pham Hieu Quang&option=202" target="_blank" rel="nofollow">Pham Hieu Quang;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Hwang Eui‐Hyung&option=202" target="_blank" rel="nofollow">Hwang Eui‐Hyung;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Kwon Young‐Gil&option=202" target="_blank" rel="nofollow">Kwon Young‐Gil;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Song Seung‐Wan&option=202" target="_blank" rel="nofollow">Song Seung‐Wan;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Department of Chemical Engineering and Applied ChemistryChungnam National UniversityDaejeon 34134 Republic of Korea;</p> <p>Leechem Co.
