Organic electrode material can be obtained from biomass through green process, so it is a sustainable green electrode material. However, the capacity attenuation problem of organic electrode seriously affects its application in the field of batteries. Desodiation state and sodiation state are the two corresponding states of electrode materials in redox reaction. The reason for this problem is that the reported desodiation state or sodiation state of organic electrode active unit cannot exist stably in aprotic electrolyte. Here, we report a new organic active unit sodium tert-butoxide (STB), which can exist stably in aprotic electrolyte to obtain high cycle stability. As the electrode of rechargeable batteries, the STB exhibits a capacity of 206 mAhg⁻¹ at 35 mAg⁻¹, 2.4 V. The battery runs more than 5000 cycles at 210 mAg⁻¹, 135 mAhg⁻¹, no capacity attenuation. The other two battery samples run more than 6500 cycles and 10000 cycles at 600 mAg⁻¹, with the capacity retention 99% and 98%, respectively. STB provides a design basis for the development of organic electrode materials with high energy density and high cycle stability.

有机电极材料可以从生物质中通过绿色工艺获得，是一种可持续的绿色电极材料。然而，有机电极的容量衰减问题严重影响了其在电池领域的应用。脱钠态和钠化态是电极材料在氧化还原反应中对应的两种状态。造成这一问题的原因是所报道的有机电极活性单元的脱钠态或钠化态在非质子电解质中不能稳定存在。在这里，我们报道了一种新的有机活性单元叔丁醇钠（STB），它可以稳定地存在于非质子电​​解质中以获得高循环稳定性。作为可充电电池的电极，STB在 35 mAg ^{-1时的容量为 206 mAhg -1, 2.4 V。电池在 210 mAg -1} , 135 mAhg ^-1下运行超过 5000 次循环，没有容量衰减。^{其他两个电池样品在 600 mAg -1}下运行超过 6500 次循环和 10000 次循环，容量保持率分别为 99% 和 98%。STB为开发具有高能量密度和高循环稳定性的有机电极材料提供了设计依据。
