Abstract: An electrolyte, an electrochemical device containing same, and an electronic device. Specifically, an electrolyte, including dimethyl carbonate, ethyl methyl carbonate, and lithium bis(oxalato)borate. The ethyl methyl carbonate and the lithium bis(oxalato)borate each account for a specified weight percent in the electrolyte, and the weight percent of the dimethyl carbonate and the weight percent of the ethyl methyl carbonate in the electrolyte meet a specified relationship. The electrolyte provides with balanced rate performance, the low-temperature discharge performance, and the high-temperature storage and cycle performance of the electrochemical device, and helps to achieve excellent comprehensive performance of the electrochemical device.
