摘　　要：研究了采用3,4,9,10-四甲酰二亚胺(PTCDI)模拟负极的乙酸铵电解质来实现高性能铵离子电池。本研究发现,由于高铵离子含量抑制了离子传输并阻碍了铵离子嵌入/脱出PTCDI电极,因此最高浓度的电解质并不具有最佳的电化学性能。研究给出了一个新的结果,即“盐包水”电解质可能不是最佳的性能,并提供了合适的电解质应平衡离子传输的方法。In this article,3,4,9,10-tetramethylenediamine(PTCDI)was used as a simulated negative electrode in ammonium acetate electrolyte to achieve high-performance ammonium ion batteries.The results showed that because the high content of ammonium ions inhibited ion transport and hindered the insertion/removal of ammonium ions in PTCDI electrodes,the electrolyte with the highest concentration did not have the best electrochemical performance.This study presents a new result that"salt in water"electrolytes may not be the optimal performance,and provides a suitable method for balancing ion transport in electrolytes.
