Abstract
This work presents a prototype solid-state symmetric supercapacitor (SSS) using cobalt iron phosphate-anchored multiwalled carbon nanotubes (MWCNT/Co3Fe4(PO4)6) with a polyvinyl alcohol‑potassium hydroxide (PVA-KOH) gel electrolyte. This advanced structure overcomes issues of the liquid electrolytes like leakage and degradation, enhancing mechanical resilience and longevity. The device exhibited a specific capacitance of 68.6 F g−1, with energy and power densities of 21.4 Wh kg−1 and 2147.8 W kg−1 at 1 mA cm−2. Notably, the device also retained 91 % capacitance over 2000 cycles, demonstrating superior electrochemical properties, mechanical adaptability, and potential for next-generation portable energy storage technologies.
本研究提出了一种固态对称超级电容器(SSS)的原型,使用磷酸铁钴锚定多壁碳纳米管(MWCNT/Co3Fe4(PO4)6)和聚乙烯醇-氢氧化钾(PVA-KOH)凝胶电解质。这种先进的结构克服了液体电解质泄漏和降解等问题,提高了机械弹性和使用寿命。该器件在1ma cm−2下的比电容为68.6 F g−1,能量和功率密度分别为21.4 Wh kg−1和2147.8 W kg−1。值得注意的是,该装置在2000次循环中还保持了91%的电容,展示了卓越的电化学性能、机械适应性和下一代便携式储能技术的潜力。
期刊介绍:
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
