Green,cheap and rechargeable Al-N2 battery with efficient N2 fixation
Battery technologies have obtained great attention due to their wide-ranging applications in present and emerging fields”1,2”,and great progress in exploring novel battery technologies has been achieved”3,4”.However,there is still huge room to develop new kinds of battery technologies with the appearance of new materials,technologies and ideas”5”.Compared with some metal(e.g.,Li,Na,K,Mg,Zn)-based batteries,Al-based batteries have more advantages in cost and safety”6”.In addition,some emerging metal-CO2 or N2 batteries with gas cathodes can not only provide energy storage,but also converse CO2 into liquid fuels,or N2 into NH3 to replace the energy-intensive Haber-Bosch process”7”.Although some progresses in metal-gas batteries(Li-CO2 battery,Na-CO2 battery,K-CO2 battery,Li-N2 battery,Na-N2 battery)have been made”8,9”,low-cost Al-N2 battery has rarely been reported.Recently,one attractive paper published in Energy&Environmental Science reported a rechargeable Al-N2 battery with efficient N2 fixation”10”.This kind of batteries has two obvious advantages:low-cost energy storage and artificial N2 fixation.
