Ni-Zn, Zn-MnO2, and Zn-air batteries have the advantages of inflammability, material abundance, and high specific energy. However, their applications are limited by the poor rechargeability of zinc anodes, which are related to shape changes, dendrite growth, corrosion, passivation, dissolution, etc. In this study, we developed a zeolitic-imidazolate framework (ZIF)-based route to construct a novel ZnO/Sb composite anode. The resultant zinc anode is scaffolded on carbon cloth (CC) and then encapsulated by carbonized resorcinol-formaldehyde resins. Such a carbon-framed ZnO/Sb anode shows the excellent rate and cycling properties because Sb suppresses the corrosion and improves interparticle conductivity, and the ZIF-derived carbon frame accommodates the shape changes, blocks the zinc dissolution, and accelerates the charge transfer. This work demonstrates the effectiveness of anti-corrosion and carbon-framed structure design on pouch and cable-like Ni-Zn batteries.

碳骨架上ZIF衍生的ZnO / Sb复合支架,用于Ni-Zn电池。

Ni-Zn,Zn-MnO 2锌空气电池具有易燃,材料丰富和高比能的优点。但是,它们的应用受到锌阳极可充电性差的限制,锌阳极的可充电性与形状变化,枝晶生长,腐蚀,钝化,溶解等有关。在本研究中,我们开发了基于沸石-咪唑酸盐骨架(ZIF)的方法构造新型的ZnO / Sb复合阳极。将得到的锌阳极固定在碳布(CC)上,然后用碳化的间苯二酚-甲醛树脂封装。这种碳框架的ZnO / Sb阳极显示出极好的速率和循环性能,因为Sb抑制了腐蚀并提高了颗粒间的导电性,而ZIF衍生的碳框架适应了形状变化,阻止了锌的溶解,并加速了电荷转移。
