新型添加剂提升锌基液流电池稳定性

Core Viewpoint - The research team from Xi'an Jiaotong University has successfully addressed the key issue of zinc ion transport and electrochemical reaction mismatch in alkaline zinc-based flow batteries, providing an innovative solution for developing high-stability and long-lifetime zinc-based flow battery energy storage technology [1][2]. Group 1: Research Findings - The alkaline zinc-based flow battery is highlighted for its advantages of high safety, high voltage, and low cost, making it a research hotspot for long-duration energy storage technology in new power systems [1]. - The previous research primarily focused on single-dimensional electrolyte additive design, which struggled to collaboratively resolve the mismatch between ion transport and reaction kinetics [1]. - The innovative concept of "organic molecular differential lock" was proposed, utilizing L-serine as a multifunctional electrolyte additive to achieve precise control over the electrolyte phase and electrode interface [1]. Group 2: Performance Improvement - The alkaline zinc-iron flow battery employing this strategy can operate stably for over 230 hours at a current density of 50 mA/cm², significantly enhancing cycling stability [2]. - The research reveals the multiple action mechanisms of the Ser additive, providing new ideas and theoretical basis for performance optimization and engineering applications of zinc-based flow batteries [2].
