However, it is challenging to realize such anode-free organic batteries, especially considering the complete absence of potassium ion (K<sup>+</sup>) source preserved on both electrodes. Here, we have first introduced potassium superoxide (KO<sub>2</sub>) as a preloaded sacrificial agent on an organic cathode, serving as an external K<sup>+</sup> supply in an initial anode-free potassium-organic cell architecture. It is shown that the unique solution-mediated decomposition mechanism of KO<sub>2</sub> endows its high compensation capacity of 368.9 mAh/g (97.9% of the theoretical value) and low decomposition overpotential of below 190 mV in the absence of additional conductive agents. Differential electrochemical mass spectrometry further confirms the single-electron transfer process for the KO<sub>2</sub> decomposition with minimal CO<sub>2</sub> evolution. A proposed chemical route for synthesizing high-purity KO<sub>2</sub> could further reduce its cost and enhance synthesis efficiency (typically in 5 minutes). The proof-of-concept of anode-free organic cell configuration is demonstrated with a decent lifespan (retaining 84.9 mAh/g after 300 cycles) and reversibility (average coulombic efficiency of 99.5%). The use of KO<sub>2</sub>-based cathode additives offers an effective route to address the initial K<sup>+</sup> deficiency and enhances the electrochemical performance of burgeoning potassium-organic batteries.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"3 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147329893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
