The ability to repair damage spontaneously is termed self-healing. Self-healing polymers (SHP) are a class of smart materials that mimic the autonomous healing behavior in biological systems by detecting damage and commencing self-repair mechanisms without the need for external damage detection or manual intervention. This feature is highly desirable for rechargeable batteries because the lifetime of high-capacity electrodes, such as anodes is shortened by mechanical fractures generated during the cycling process. In this report, we used polyurethane composite material using bis (4-aminophenyl) disulfide as dynamic crosslinker for binder while coating electrodes. Structural and morphological characterizations of SHP nanocomposites are done using FT-IR, TGA, XRD, SEM and TEM. Finally electrochemical studies were carried by fabricated 2032 type coin cells using RGO-SnS2: SHP: Carbon black in the ratio of 80:10:10 respectively. |
