MXene Clay-containing water-based binder with hollow core shell structure for silicon anode in lithium-ion battery |
| 초록 |
Silicon (Si) as an anode material has attracted great attentions because of its advantages of high theoretical capacity (~4200 mAh/g), low operation voltage, and abundant resources. However, Si anodes suffer from severe capacity fading during charge/discharge process, resulting from the huge volumetric change (~300%) of Si[1]. The repeated volumetric change of Si loosens the particle-to-particle contacts, leading to the pulverization and electrical isolation of Si particles and delamination of the electrode from the current collector[2]. These undesirable phenomena hinder its application to lithium-ion batteries (LIBs). binder is an optional alternative than can effectively suppress the series problems by facile fabrication process and low cost. The fundamental role of binder in an electrode is to maintain the electrical network of the electrode by both the cohesion of the electrode components (e.g., active material and conductive agent) and the adhesion to current collector during the cell operation. In this regard, the binder is expected to play a significant role in the mechanical stability of electrodes and their long-term cycling performance[3]. |
