突出了通过电聚合技术在二氧化钛纳米管（TiO 2nts）上保形涂覆聚氧化乙烯（PEO）基聚合物电解质的益处。由于存在聚合物电解质涂层的纳米管，半电池的容量提高了45%，在1C下相比，裸TiO 2nts。在50次循环中，全电池中的聚合物涂层TiO 2nts在LiNi0.5M1.5O4、LiFePO 4和LiCoO 2的情况下分别提供了<$30 μA h cm − 2（120 mA h g − 1）、<$25 μA h cm−2（100 mA h g−1）和<$23 μA h cm−2（90 mA h g−1）的平均容量。
The benefits of the conformal coating of polyethylene oxide (PEO)-based polymer electrolyte by the electropolymerization technique on titania nanotubes (TiO2nts) are highlighted. Due to the presence of polymer electrolyte coating the nanotubes, the capacity of the half cell is improved by 45% at 1 C compared to bare TiO2nts. The polymer-coated TiO2nts in the full cell deliver an average capacity of ∼30 μA h cm−2(120 mA h g−1) with LiNi0.5M1.5O4, ∼25 μA h cm−2(100 mA h g−1) with LiFePO4and ∼23 μA h cm−2(90 mA h g−1) with LiCoO2, respectively during 50 cycles.
