On the 19th, reporters obtained information from the Eighth Academy of the China Aerospace Science and Technology Corporation, revealing that a collaborative team, composed of researchers from the 811 Institute under the academy's umbrella and Nankai University, has achieved a significant milestone. They have successfully formulated a hydrofluorocarbon-based electrolyte tailored for high-energy-density batteries that excel in low-temperature conditions. This groundbreaking technological advancement has propelled lithium batteries to attain an impressive energy density of over 700 watt-hours per kilogram at ambient temperatures, and approximately 400 watt-hours per kilogram when subjected to minus 50℃ environments. Given an equivalent mass, the battery's capacity for storing electrical energy has witnessed a remarkable 2 to 3-fold increase, potentially doubling the driving range of electric vehicles. Furthermore, the battery maintains its operational integrity even at temperatures as low as minus 70℃.
