| 3 | Materials,fundamentals,and technologies of liquid metals toward carbon neutrality显示文摘Carbon-neutral technologies are critical to ensure a stable future climate.Currently,low-melting-point liquid metals are emerging rapidly as important energy materials with significant potential to contribute to carbon neutrality.The advantages of gallium-and bismuth-based liquid metals,such as their high fluidity,low melting point,high thermal/electrical conductivity,unique chemical properties,non-flammability,and nontoxic characteristics,render them highly attractive for the development of advanced carbon-neutral technologies.Although their significance in both academia and industry has increased gradually,to the best of our knowledge,a systematic monograph of liquid-metal materials,mechanisms,and technologies toward carbon neutrality is not yet available.Therefore,we presented a comprehensive review of low-melting-point liquid metals for carbon neutrality.First,liquid-metal materials,including fluids,pastes,solids,and their composites were introduced.Subsequently,the mechanisms of liquid-metal technologies used to achieve carbon neutrality were interpreted.Finally,typical liquid-metal applications of carbon neutrality in the power,industry,transport,and building sectors were presented.Both the fundamental mechanisms and promising technologies were elaborated upon,and the critical assessment criteria for carbon-neutral technologies were discussed.The scientific and technical challenges and future perspectives in these areas were also highlighted. | DENG YueGuang E ErTai LI Jing JIANG Yi MEI ShengFu YU Yang | 2023 | Science China(Technological Sciences)2023，66，6： | 0 |
