Li metal anodes are a key component of high-energy-d. Li-S (Li-S) batteries. However, the issues associated with Li anodes remain unsolved owing to the immature Li anode construction and protection technol., which leads to internal short circuits, poor capacity retention, and low coulombic efficiency for high-S-loading Li-S batteries. Herein, a highly stable 3-dimensional Li C fiber composite (3-dimensional LiCF) anode for high-S-loading Li-S batteries was demonstrated, in which a self-formed hybrid solid-electrolyte protection layer was constructed on a Li metal surface through codeposition of thiophenolate ions and inorganic Li salts by using di-Ph disulfide as a co-additive in the electrolyte. The aromatic components from thiophenolate could improve the stability of the protection layer, and the 3-dimensional structure of the C fiber could effectively buffer the volume effect during Li cycling. A Li-S battery based on a 3-dimensional LiCF anode exhibited excellent cycling stability with an energy efficiency of 89.2% for 100 cycles in terms of a high energy d. of 22.3 mWh cm-2 (10 mAh cm-2 area capacity of Li cycling). This contribution demonstrates versatile and ingenious strategies for the construction of a 3-dimensional Li anode structure and protection layer, providing an effective solution for practical stable Li-S batteries. After reading the article, we found that the author used 1,2-Diphenyldisulfane(cas: 882-33-7Application of 882-33-7)
1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers.Oxygen is more electronegative than carbon, thus the alpha hydrogens of ethers are more acidic than those of simple hydrocarbons. They are far less acidic than alpha hydrogens of carbonyl groups (such as in ketones or aldehydes), however. Application of 882-33-7
