中文摘要: 枝晶在金属-空气电池充电过程中因界面的稳定性遭到破坏而形成,枝晶的形成会引起金属-空气电池安全性以及寿命短等问题。通过抑制金属-空气电池的枝晶生长可解决其安全性以延长其使用寿命,并提高电池的性能和使用寿命,这就需要深入研究枝晶的生长机理、并在理解生长机理的基础上对枝晶进行抑制。本文系统的阐述了金属-空气电池电沉积过程中枝晶的生长机理的研究现状以及金属-空气电池充电过程中枝晶抑制方法的研究现状。通过实验研究:发现金属负极改性和结构设计、改良电解液可有效抑制枝晶生长;仿真模拟研究发现:调节阳极界面附近的温度来调节锂的均匀沉积,可以抑制枝晶生长。在今后枝晶生长的研究中,实验与模拟相结合将成为主要手段,可进一步电流特性、电解液性质以及催化剂催化性能对枝晶抑制的协同作用,从而获得更有效的金属-空气电池枝晶抑制方法。
Abstract:Dendrites are formed due to the destruction of the stability of the interface during the charging process of the metal-air battery. The formation of dendrites can cause problems such as the safety and short life of the metal-air battery. By inhibiting the dendrite growth of the metal-air battery, its safety can be solved to prolong its service life and improve the battery’s performance and service life. This requires in-depth study of the growth mechanism of dendrites, and an understanding of the growth mechanism. Dendrites are suppressed. This paper systematically describes the current research status of the growth mechanism of dendrites during the electrodeposition of metal-air batteries and the current research status of dendrite suppression methods during the charging process of metal-air batteries. Through experimental research, it is found that the modification and structural design of the metal negative electrode and the improved electrolyte can effectively inhibit the growth of dendrites; the simulation study found that adjusting the temperature near the anode interface to regulate the uniform deposition of lithium can inhibit the growth of dendrites. In the future study of dendrite growth, the combination of experiment and simulation will become the main method, which can further enhance the synergistic effect of current characteristics, electrolyte properties and catalyst catalytic performance on dendrite suppression, so as to obtain more effective metal-air battery dendrites Suppression method.
