The usability of novel Fe₂NiO₄-spinel/YSZ composites as storage components for rechargeable oxide batteries (ROB) is assessed. Continuous thermogravimetric analysis while cycling between oxidizing and reducing conditions revealed a much better robustness of these composites as compared to iron oxide storage materials, which suffer from densification and exhibit severe charge capacity fading when redox-cycled. The scaffolded structure and the nickel containing redox-active spinel greatly reduce such densification and sustain fast redox reactions. Both oxidation and reduction rates of the composites are significantly enhanced by increasing their porosity, leading to better gas penetration of the redox shuttle gas used in ROBs to transfer oxygen between the storage component and the membrane electrode assembly.

新型Fe ₂ NiO ₄的可用性评估了-spinel / YSZ复合材料作为可充电氧化物电池（ROB）的存储组件。与氧化铁存储材料相比，在氧化和还原条件之间循环的同时进行连续热重分析表明，这些复合材料的坚固性要好得多，而氧化铁存储材料受致密化影响，并且在氧化还原循环时显示出严重的充电容量衰减。支架结构和含镍的氧化还原活性尖晶石大大减少了这种致密化并维持了快速的氧化还原反应。通过增加其孔隙率，可以显着提高复合材料的氧化率和还原率，从而使ROB中使用的氧化还原穿梭气更好地渗透气体，从而在存储组件和膜电极组件之间转移氧气。
