锂硫电池Li2S阴极 用EFTEM确定Li2S@C的工作？做出了N掺杂的Li2S/CB@C纳米核壳结构，应用于锂硫电池阴极，初始容量很高。并且用TEM配合EFTEM获得核壳照片。Li2S第一篇用EFTEM表征的工作。 摘要：Using high-energy ball milling of the Li2S plus carbon black mixture followed by carbonization of pyrrole, we have established a facile approach to synthesize Li2S-plus-C composite particles of average size 400 nm, encapsulated by a nitrogen-doped carbon shell. Such an engineered core–shell structure exhibits an ultrahigh initial discharge specific capacity (1029 mA h g1), reaching 88% of the theoretical capacity (1166 mA h g1 of Li2S) and thus offering the highest utilization of Li2S in the cathode among all of the reported works for the encapsulated Li2S cathodes. This Li2S/C composite core with a nitrogen-doped carbon shell can still retain 652 mA h g1 after prolonged 100 cycles. These superior properties are attributed to the nitrogen-doped carbon shell that can improve the conductivity to enhance the utilization of Li2S in the cathode. Fine particle sizes and the presence of carbon black within the Li2S core may also play a role in high utilization of Li2S in the cathode.查看更多1个回答 . 16人已关注
审稿意见里的标准平衡电位怎么确定?Comment 9: For each electrochemical reaction, the standard equilibrium potential should be specified. 审稿人给出的意见，这里的每个电化学反应给出标准平衡电位，指的是查文献得到的电位数据，还是自己的CV曲线中的峰位换算成标准电位呢？ QQ图片20170807151839.png查看更多7个回答 . 3人已关注
