Abstract

Nowadays, researchers are working hard to design and developmethods to store electricity for the future demands of zero-emission energy production methods and transportation. Many efforts have been made to improve the safety of portable electronic devices. In this regard, many researchers have studied different materials to develop non-flammable electrolytes for electrochemical double-layer capacitors (EDLC) and lithium-ion batteries (LIBs), which power electronic devices. The need to develop efficient and fire-safe energy storage devices has led to the widespread use of fluorinated electrolytes as a substitute for ionic liquid-based electrolytes. Although fluorinated electrolytes have many advantages over other electrolytes, their widespread usage created new challenges, especially environmental problems. Thus, the electrolytes of ...
