钠电池是否耐过放？

Is Sodium-ion Battery resistant to over discharge?    

钠离子电池的耐过放性能极为突出，容错率远高于锂离子电池，是其适配民用、工业复杂场景的重要优势。锂电池深度过放后极易造成电极活性物质永久性失效，导致容量大幅衰减、电池报废，甚至出现鼓包、短路风险；而钠电池化学稳定性好，电极结构抗损伤能力强，即使出现深度过放、电量完全放空的情况，也不会造成永久性结构损坏，补电后可快速恢复正常性能，容量无明显损耗。在日常使用、户外应急、储能备用等复杂工况下，轻微过放、偶尔深度放电不会影响电池寿命，使用容错率更高、更耐造。

Sodium-ion Battery has extremely outstanding over discharge resistance, and its fault tolerance is much higher than that of Lithium-ion Battery, which is an important advantage for it to adapt to civil and industrial complex scenarios. After deep over discharge, Lithium-ion Battery is very easy to cause permanent failure of electrode active materials, resulting in large capacity attenuation, battery scrapping, and even the risk of swelling and short circuit; while Sodium-ion Battery has good chemical stability and strong anti-damage ability of electrode structure. Even if deep over discharge occurs and the power is completely discharged, it will not cause permanent structural damage, and can quickly recover normal performance after recharging, with no obvious capacity loss. In daily use, outdoor emergency, energy storage backup and other complex working conditions, slight over discharge and occasional deep discharge will not affect the battery life, with higher use fault tolerance and more durable.
