海水电池用Mg-Ga-Hg合金在模拟深海环境下的性能
Performance of Mg-Ga-Hg alloy for seawater battery under simulated deep-sea environment
摘要
Abstract
Mass loss measurement,open circuit potential (OCP) and galvanostatic discharge methods were used to assess the electrochemical performance of Mg-Ga-Hg alloy in its initial and intermittent periods under simulated deep-sea environment.The results show that the OCP of Mg-Ga-Hg alloy is lower than-1.95 V (vs.SCE) in 4 ℃ and 4 cm/s seawater,and at the discharge current density of 1-9 mA/cm2,its working potential can be kept at lower than-1.9 V (vs.SCE) with more than 50％ current efficiency due to slow self-discharge rate.Meanwhile,Mg-Ga-Hg alloy can quickly start.Therefore,Mg-Ga-Hg alloy is a promising anode material for seawater battery to provide long-term power supply for observation instrument in deep sea.关键词
