내용
Lithium-ion batteries (LIBs) play a pivotal role as energy storage devices in various domains, encompassing electronics, electric vehicles (EVs), and energy storage systems (ESS). Nonetheless, their low capacity presents a challenge in realizing next-generation LIBs. To solve this limitation, high-capacity Si have been proposed; though the issue of volume expansion during charging and discharging processes results in structural breakdown, which hinders its practical application in LIBs. Addressing this concern polymeric binders are studied to prevent structural degradation of the Si anode. Conventional binders such as polyvinylidene fluoride (PVDF), styrene butadiene rubber (SBR) and polyacrylic acid (PAA) exhibit very poor cycling performance due to weak interaction with Si. In this study, we present the development of novel polymeric binders with self-healing properties and report on their performance.
