-50℃也能高效放电！我科学家研发出锂电池“新配方”

Core Insights - The research team from Nankai University has developed a groundbreaking lithium metal battery using a novel electrolyte based on fluorine coordination, which significantly enhances energy density and low-temperature performance [1][2]. Group 1: Breakthrough Technology - The new electrolyte design replaces oxygen atoms with fluorine atoms to dissolve lithium salts, resulting in a high energy density of 700 watt-hours per kilogram for the lithium metal battery [1][2]. - The battery maintains a high energy output of nearly 400 watt-hours per kilogram even at -50 degrees Celsius, making it suitable for applications in electric vehicles and polar exploration [1][2]. Group 2: Historical Context and Innovation - Historically, the use of oxygen in electrolytes has been a standard since the invention of the battery in 1800, with traditional lithium batteries relying on lithium salts and carbonate solvents [1]. - The new fluorinated hydrocarbon solvents demonstrate better wettability and utilization, allowing for a significant reduction in electrolyte volume compared to traditional lithium-oxygen coordination systems [2]. Group 3: Application Potential - The high energy density and low-temperature resilience of the new battery technology present vast application potential in sectors such as electric vehicles, intelligent robotics, low-altitude economy, and aerospace [5].
