Abstract

This application provides an electrolyte, an electrochemical apparatus, and an electronic apparatus. The electrolyte includes at least two of an additive I, an additive II, or an additive III. The additive I is at least one additive selected from a group consisting of a compound represented by the following formula 1a, a compound represented by the following formula 1b, and lithium difluorophosphate; <img class="EMIRef" id="55205f61-b062-4132-b383-971b74297284-ia01" /> and <img class="EMIRef" id="55205f61-b062-4132-b383-971b74297284-ia02" /> The additive II is at least one additive selected from a group consisting of lithium fluorosulfonate, difluorosulfonimide, and bistrifluoromethane sulfonimide. The additive III is at least one additive selected from a group consisting of lithium difluorooxalate borate, lithium bisoxalate borate, and lithium tetrafluoroborate. The electrolyte provided in this application can improve the low-temperature performance and reduce the resistance and thickness swelling rate of electrochemical apparatuses.
