Delaying the inevitable: Hydrolysis of MOF and coordination polymer electrode materials in alkaline electrolyte is inevitable. However, we have found that the hydrolysis of cyanide-bridged nickel-based coordination polymer electrode materials can be suppressed by the introduction of pillared pyrazine ligands; this optimizes the electrochemical performance. The possible mechanism of partial hydrolysis of electrode materials was proposed, and the hypothesis was justified by ex situ electrochemical and structural characterization.

柱配体诱导氰化物配位聚合物的部分水解，优化可充电碱性电池的电化学动力学

延迟不可避免：MOF 和配位聚合物电极材料在碱性电解质中的水解是不可避免的。然而，我们发现通过引入柱撑吡嗪配体可以抑制氰化物桥接镍基配位聚合物电极材料的水解；这优化了电化学性能。提出了电极材料部分水解的可能机制，并通过非原位电化学和结构表征证明了这一假设。
