Despite having promising Li storage properties such as multielectron reactions and fast kinetics, organic electrode materials exhibit poor cycling stability, which is partly caused by their tendency to dissolve in liquid electrolytes. In this work, an all-solid-state Li-organic battery with excellent cycling stability and high discharge voltage was designed, in which poly(2-chloro-3,5,6-trisulfide-1,4-benzoquinone) (PCTB) and poly(ethylene glycol) (PEO)-based composite polymer electrolyte (CPE) served as the cathode and electrolyte respectively. The PEO-LiClO₄-10 wt% Li_0.3La_0.566TiO₃ (LLTO) electrolyte has an excellent ionic conductivity of 7.99 × 10⁻⁴ S cm⁻¹ at 343 K. Furthermore, the all-solid-state battery exhibited a high discharge capacity of 104 mAh g⁻¹ with an average potential of 2.72 V at 343 K. After 300 cycles, 90% of the maximum capacity was retained. These results shed light on the application of carbonyl compounds in conjunction with PEO-based electrolytes for Li-ion batteries.

尽管有机电极材料具有令人满意的锂存储特性，例如多电子反应和快速动力学，但其循环稳定性差，这部分是由于它们溶解在液体电解质中的趋势所致。在这项工作中，设计了一种具有出色的循环稳定性和高放电电压的全固态锂有机电池，其中的聚（2-氯-3,5,6-三硫化物-1,4-苯醌）（PCTB）聚乙二醇（PEO）基复合聚合物电解质（CPE）分别用作阴极和电解质。PEO-LiClO ₄ -10 wt％Li _0.3 La _0.566 TiO ₃（LLTO）电解质具有出色的离子电导率7.99×10 ^-4  S cm ^-1此外，全固态电池在343 K时表现出104 mAh g ^-1的高放电容量，平均电势为2.72V。300次循环后，最大容量保留了90％。这些结果揭示了羰基化合物与基于PEO的锂离子电池电解质的结合应用。
