“…This difference about K‐ion storage contribution is believed to give rise to the increased cycling stability for PTCDA‐0C electrode at 7.35 C. The energy‐power densities and cycling performance of PTCDA‐0C and PTCDA‐2C are truly outstanding. The energy‐power performance of the battery using the PTCDA‐0C cathode is highly competitive with the‐of‐the‐art organic cathode materials for PIBs ( Figure a) . Meanwhile, because of the extraordinary capacity of PTCDA‐2C electrode at ultrahigh current densities, corresponding potassium‐organic battery presents superiority in energy density than many reported inorganic cathodes including Prussian Blue and KVOPO 4 when the power density over 9555 W kg −1 (Figure S5, Supporting Information) .…”

Potassium-organic batteries have a great potential for applications in large-scale electricity grids and electric vehicles because of their low cost and sustainability. However, their inferior cycle stability and more importantly low energy density under fast discharge/charge process of organic cathodes limit their applications. This work introduces a simple polymerization processing which enables comprehensive tuning of redox kinetics, electronic structures, and electrode/electrolyte interfaces of the polymer cathodes. With this approach, a potassium-organic battery with an impressive energy density of 113 Wh kg −1 at a high power of 35.2 kW kg −1 is shown which corresponds to a high current density of 147 C and a fully discharge within 10 s. The battery also has impressive cycling stability that a 100% Columbic efficiency is maintained and shows negligible capacity degradation after 1000 cycle at a high current density of 7.35 C. Using the polymer cathode and a dipotassium terephthalate anode, a full battery with superior energy density and cycling stability is demonstrated among all reported all-organic full potassium ion batteries.

The demands for high-performance and low-cost batteries make K-ion batteries (KIBs) considered as promising supplements or alternatives for Li-ion batteries (LIBs). Nevertheless, there are only a small amount of conventional inorganic electrode materials that can be used in KIBs, due to the large radius of K+ ions. Differently, organic electrode materials (OEMs) generally own sufficiently interstitial space and good structure flexibility, which can maintain superior performance in K-ion systems. Therefore, in recent years, more and more investigations have been focused on OEMs for KIBs. This review will comprehensively cover the researches on OEMs in KIBs in order to accelerate the research and development of KIBs. The reaction mechanism, electrochemical behavior, etc., of OEMs will all be summarized in detail and deeply. Emphasis is placed to overview the performance improvement strategies of OEMs and the characteristic superiority of OEMs in KIBs compared with LIBs and Na-ion batteries.

“…Unfortunately, OHTAP only showed a reversible capacity of 220 mAh g −1 , which did not reach the expected capacity value. This may be due to the steric hindrance effect that prevents all active sites from participating in the redox reaction [9g] . In this case, how to design more favorable embedding/de‐embedding materials for K + is worth exploring in the future.…”
