AB  - <p>A supercapacitor diode (CAPode), which combines both functions of energy storage and the current rectification, shows strong potential for a wide range of applications. However, it remains a big challenge to achieve flexible CAPodes with high performance because of limitations in electrode and electrolyte materials. In this study, we construct a high-performance flexible CAPode by synergistical optimization of electrodes and polymer electrolyte. The ion–sieving effects of oxygen–deficient intercalated transition metal oxide (MoO<sub>x</sub>) are revealed by experimental results and theoretical calculation. The resultant quasi-solid-state CAPode not only shows high specific capacitance and rectification ratio, but also exhibits excellent mechanical flexibility. The CAPodes-based "AND" and "OR" logic gates with good processing ability are also built and investigated.</p>
