摘要

为了提高铅酸电池的电压和性能，本研究引入了一种多电解质配置：PbO2在H2SO4中，Pb在NaOH中，通过离子交换膜隔离。通过循环伏安法（CV）、阻抗谱法和电流测量分析了Pb在NaOH中的电化学行为。CV揭示了氧化还原过程和电压特性，阻抗提供了动力学参数，电流瞬态阐明了成核和生长动力学。本设计充分利用了Pb在碱中的低电位（−0.9 V）和PbO2在酸中的高电位（+1.5 V），实现了2.4 V的显著工作电压，提出了一种有前景的优化策略。

Investigating the Behavior and Kinetics of Lead Electrode in Sodium Hydroxide Solution for Application in Dual-Electrolyte Lead Batteries

Seeking higher voltage and performance in lead–acid batteries, this research introduces a multielectrolyte configuration: PbO₂ in H₂SO₄ and Pb in NaOH, isolated by an ion-exchange membrane. The electrochemical behavior of Pb in NaOH was analyzed via cyclic voltammetry (CV), impedance spectroscopy, and current measurements. CV revealed redox processes and voltage characteristics, impedance provided kinetic parameters, and current transients elucidated nucleation and growth dynamics. This design leverages the low potential of Pb in alkali (−0.9 V) and the high potential of PbO₂ in acid (+1.5 V), achieving a significant 2.4 V operating voltage, presenting a promising optimization strategy.
