针对铝-空气电池阳极极耳提前断裂的问题，通过三电极体系测试25～60℃下Al-In-Sn-Ga-Pb合金阳极的极化曲线，结合24 V/30 A电池组的温度-功率密度实验，揭示温度对阳极腐蚀行为的影响机制。结果表明：60℃时，阳极极化曲线无钝化区，腐蚀电流密度达1.8 A/cm²，较25℃提升5倍；50℃时，功率密度峰值为208.1 mW/cm²，高温下因电解液浓缩与氧传质限制导致功率增益趋缓。基于流体力学模型量化温度差对消耗速率的影响，提出将反应温度控制在(50±2)℃，以延长极耳寿命。该方案为大功率铝-空气电池的工程化应用提供温度调控与材料优化依据。

In response to the problem of premature fracture of the anode plate ears in aluminum-air batteries, the polarization curve of Al-In-Sn-Ga-Pb alloy anodes at 25～60 ℃ was tested using a three electrode system. Combined with temperature power density experiments on 24 V/30 A battery packs, the influence mechanism of temperature on anode corrosion behavior was revealed. The results showed that there was no passivation zone in the anodic polarization curve at 60 ℃, and the corrosion current density reached 1.8 A/cm2, which was 5 times higher than that at 25 ℃; The peak power density at 50 ℃ is 208.1 mW/cm2, and the power gain slows down at high temperatures due to electrolyte concentration and oxygen mass transfer limitations. Based on a fluid dynamics model to quantify the effect of temperature difference on consumption rate, It is proposed to control the reaction temperature at(50±2) ℃ to extend the lifespan of the tab. This scheme provides temperature control and material optimization basis for the engineering application of high-power aluminum-air batteries.
