水系電池（Aqueous Batteries, ABs）具有成本低、安全、環保、易組裝、離子電導率高等優點。在水系電解液中，大多採用鈦、不銹鋼、鎳等具有電化學穩定性材料作為集流體。這些昂貴的材料作為集流體限制了水系電池於大型儲能系統的應用。然而，商業化的鋁箔集流體在水溶液環境中容易有腐蝕的問題，因此，抑制鋁箔的腐蝕是關鍵因素。在本研究中，為了改善鋁箔集流體於水系電解液中腐蝕的問題，我們使用了對環境友善且低成本的含氮有機物苯並咪唑(Benzimidazole, BI)和苯並三唑(Benzotriazole, BTA)作為腐蝕抑制劑，在添加劑效能的評估中，SEM鋁箔表面分析可以看到經過線性極化後的鋁箔表面腐蝕產物和孔蝕得到了顯著的抑制。X射線光電子能譜結果證實鋁箔表面的天然氧化層逐漸的氧化為氫氧化物，因其耐腐蝕性較差會進一步腐蝕為Al3+並溶在電解液中。在Zn/LFP水系雙離子電池以兩種方法 ― 添加劑加於電解液中以及混合於正極材料中。兩種添加方法其循環後的鋁箔集流體經由EDS元素分析證實鋁含量較高，氧含量減少，說明皆有抑制腐蝕的效果。Zn/LFP水系雙離子電池以0.2C-rate充放電速率下，將添加劑混合於電極之中有較佳的電化學表現，推測能夠降低添加劑對於鋅陽極的副反應。在50圈循環後原來的LFP電容量保持率為81%，分別混合BI和BTA添加劑為91.87%和74.85%，BI添加劑明顯改善電池的電化學性能並且有較好的穩定性。在使用環保且低成本的含氮有機抑制劑來提昇水性電池集流體的耐蝕，是邁向低成本和安全儲能應用的重要一步。

Aqueous batteries (ABs) are low cost, safe, environmentally friendly, easy to assemble, highly ionic conductive. Among the aqueous electrolyte, most use titanium, stainless steel, and nickel as the current collector because of the electrochemical stability in the aqueous electrolyte. However, the cost limits to commercialize ABs for large energy storage. Commercial current collector, aluminum, is prone to corrosion in an aqueous environment; therefore, the inhibition of aluminum corrosion is a key factor. Here, we introduce eco-friendly and low-cost nitrogen-contained organic inhibitors, benzimidazole (BI) and benzoitriazole (BTA), to solve corrosion. The SEM shows that corrosion products and pitting on Al current collector are significantly inhibited after cycling in both methods to evaluate the additive effects. X-ray photoelectron spectroscopy results confirmed that the passivating oxide film on the aluminum surface was gradually degraded into hydroxide, which is less corrosion resistance and further corroded into Al3+ in the electrolyte. Two methods have been considered and implemented in the aqueous Zn/LFP batteries― additives present in the electrolyte and mixed with cathode material. EDS elemental analysis confirms that the aluminum content increased and the oxygen content decreased from the cycled aluminum current collector in both methods, indicating that the additives have the effect of inhibiting corrosion. The better electrochemical performance is obtained by mixing the additives with cathode material, which may be attributed to the reduction of additives side reaction with Zn anode. The capacity retention of pristine LFP is 81%, BI and BTA additive capacity retention are 91.87% and 74.85% after 50 cycles at 0.2C-rate, respectively. The use of eco-friendly and low-cost nitrogen-containing organic inhibitors for corrosion-resistant current collectors for aqueous batteries marks an important step toward low-cost and safe energy storage applications.
