To align with sustainability goals and reduce costs, there is a pressing need for water‐processable alternatives. These alternatives can halve electrode processing costs and ease regulatory burdens. While progress has been made with water‐processed graphite electrodes using eco‐friendly binders, challenges persist for high‐mass loading activated carbon (AC) electrodes. This study investigates the impact of modified aluminium current collectors on water‐processed AC electrodes, focusing on compatibility, processability, and electrochemical performance. Various aluminium foils, including etched and carbon‐coated types, were evaluated. The results show that modifications at the interface significantly improve the wetting properties and mechanical stability. Electrochemical tests revealed that carbon‐coated aluminium provided the lowest internal resistance and highest rate capability due to intimate contact between the electrode components. In contrast, etched aluminium foil exhibited higher contact resistance and poorer performance. Ageing studies demonstrated that carbon‐coated foils maintained better electrochemical performance over time, as the carbon layer reduced degradation reactions and contact resistance. These findings suggest that uniformly carbon‐coated aluminium current collectors are the optimal choice for high‐power electrochemical capacitors, balancing performance, sustainability, and cost‐efficiency.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"83 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141782844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their low metal ion transport and unstable electrode electrolyte interface make their mass production a huge question. To bridge the emerging solid state and traditional liquid electrolytes, we focus on Quasi-Composite Polymer electrolytes (QCPE). Herein, we develop QCPE with active 3D alumino-silicate zeolitic ion conduction pathways embedded in a polymer matrix using two techniques- solution casting and electrospinning. Electrospun QCPE outperforms Solution cast QCPE by achieving high amorphous behavior. Prompt elimination of solvent during electrospinning decreases bulk resistance and increases its ionic conductivity. The Zeolitic pathway anchored by hydroxyl groups of PVA polymer acts as a highway for Li+ ions. It exhibits highly stable platting stripping vs Li+/Li for 450 hours with low overpotential, confirming the interfacial compatibility and dendrite-free cycling at lithium metal anode. Controlled lithium-ion nucleation regulated by evenly distributed zeolitic pathway is an interesting front of this work. To test QCPE's performance in Lithium metal battery (LMB), the electrospun QCPE is used to fabricate LMB with LiFePO4 cathode. This battery system delivered a high capacity of 155 mAh g−1 at 0.1 C. In addition to the high performance, electrospun QCPE production is scalable at an industrial scale.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"7 11","pages":""},"PeriodicalIF":5.1,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141782846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of high‐performance and durable non‐noble metal catalysts for the cathodic oxygen reduction reaction (ORR) is crucial for advancing the practical use of Mg‐air batteries. The synergistic interaction between different metals in bimetallic catalysts is an effective strategy for enhancing the activity and stability of the catalysts. Herein, various prussian blue analogues (PBA) were selected as precursors to synthesis the bimetallic CoNi@NC, monometallic Co@NC and Ni@NC catalysts due to tunable chemical compositions. Compared with Co@NC and Ni@NC, the bimetallic CoNi@NC pyrolyzed at 600°C (CoNi@NC‐600) exhibits outstanding ORR performances and stability in alkaline (0.1 M KOH) and neutral (3.5 wt% NaCl) electrolytes. Following 5000 CV cycles, the half‐wave potentials for CoNi@NC‐600 show only minor negative shifts of 8 and 7 mV, respectively. Meanwhile, the CoNi@NC‐600 possesses the similar ORR reaction mechanism and activity with Pt/C. The primary Mg‐air battery assembled with CoNi@NC‐600 displays better discharge performances than that of Co@NC and Ni@NC.

Furthermore, the influence of electrode overhang, which is relevant for upscaling, is evaluated.
