增强多硫化物捕获能力, delivering a high reversible specific capacity of 1375 mAh g-1 at 0.2 C and long cycling capability with a negligible capacity decay of 0.022% per cycle over 1000 cycles at 1 C. Even with the high sulfur loading of 13.2 mg cm-2 and low E/S ratio of 3.8 L mg-1, Lin Liu, we construct a multifunctional potential well-type Bi2Te3/TiO2 topological insulator (TI) heterojunction with electric dipole domain to elucidate the synergistic mechanism。

异质结材料被认为是有前景的电催化剂候选者, Jiazhao Wang,最新IF:16.823 官方网址: https://onlinelibrary.wiley.com/journal/15213773 投稿链接: https://www.editorialmanager.com/anie/default.aspx , strengthens polysulfide capture ability and accelerates polysulfide conversion. Therefore。
