布拉特自由基应用于交联聚合物中，为有机自由基电池提供了一种稳定且可快速充电的电极材料。在循环伏安法（CV）实验中筛选了不同的电解质，并将该材料用作硬币电池实验的正极材料。它在60℃下表现出优异的倍率能力，在1℃下保持48%的容量，在5000次循环实验中保持稳定，容量保持56%，1000次循环后容量保持96%。电极的性能与聚合物负载无关，在20%到60%之间，使高聚合物负载成为可能。这些结果证明了一种有前途的、稳定的有机聚合物电池正极材料。
The Blatter radical is applied in a cross-linked polymer to yield a stable and quickly chargeable electrode material for organic radical batteries. Different electrolytes are screened in cyclic voltammetry (CV) experiments and the material is utilized as a cathode material in coin cell experiments. It exhibits excellent rate capabilities of up to 60 C, where it keeps 48% of the capacity at 1 C. It is stable in cycling experiments of 5000 cycles with a capacity retention of 56% and 96% capacity retention after 1000 cycles. The performance of the electrodes is independent of the polymer loading between 20 and 60 wt%, making a high polymer loading possible. These results demonstrate a promising, stable cathode material for organic polymer batteries.
