不同碳导电剂对铁-空气电池性能的影响
Impact of different carbon conductive agents on performance of iron-air battery
摘要
Abstract
Metal-air batteries(MABs)have the advantages of low cost,environmental friendliness,high specific power and specific energy,among which iron-air batteries(IAB)are more resource-rich and have high specific energy.Problems in IAB such as passivation,corrosion,self-discharge,hydrogen evolution reaction and volume change of iron electrodes restrict its development.Considering that acetylene black is commonly used as a conductive and supportive active material in the preparation of iron negative electrodes,to further investigate the impact of other carbon materials on the electrochemical performance of iron electrodes,we prepared different iron electrodes using acetylene black,graphite powder,and carbon nanotube.Corresponding iron-air batteries were assembled with the prepared iron electrodes and Pt/C air electrode.Charge/discharge curves at different current densities and discharge polarization curves were obtained on these batteries.The results indicate that the overall performance of the carbon nanotube modified iron negative electrode battery is excellent,exhibiting high cycle stability,high charge discharge voltage efficiency,and power density.This work provides reference value for the in-depth study of IAB by preparing stable and reliable iron electrodes.关键词
