Abstract
Occurrence of severe accidents related to lithium-ion batteries reflects the dire need of enhancing batteries' safety without compromising its electrochemical performance. One of the essential components of a battery is the electrolyte whose decomposition in the operating voltage range not only hampers the electricity generation process but it also detrimentally impacts the lifespan of the battery and causes battery-related hazards. Therefore, interdisciplinary researchers aim at achieving the common goal of increasing efficiency and safety of this potential energy storage system. This review article represents the key points of major risks associated with lithium-ion batteries under abuse conditions. The various strategies followed to optimize electrolytes for enhancing the overall stability and electrochemical performance of the battery are also reviewed. At the end, the potential contribution of optimized electrolytes in providing safety under abuse conditions is discussed. The enhanced and safe operational voltage range for electrolytes could make the use of high-voltage electrode materials in batteries feasible.
