一般描述

醋酸铵是一种水溶性白色结晶铵盐,具有独特的性质,这些性质使其适用于太阳能电池、电池和燃料电池催化剂。

应用

醋酸铵可用于:
  • 钝化红色LED的 CsPbI3 钙钛矿纳米晶体。醋酸铵有效地消除了不需要的表面金属铅阳离子和悬空键,以提高稳定性和光致发光量子产率(PLQY)。
  • 作为添加剂用于制造优质钙钛矿太阳能电池,其功率转换效率(PCE)提高了13.9%。它在不改变钙钛矿组成的情况下促进结晶并提高性能。
  • 作为一种经济划算的绿色电解质,用于全有机电池超级电容器混合设备,实现最大的能量密度。
  • 作为水性锌电池的电解质添加剂。它有助于提高循环稳定性和容量保持能力。
