Low Pt loading electrodes were prepared by galvanostatic pulse electrodeposition on a Nafion-bonded carbon layer. Since the electrodeposition of Pt in aqueous solution occurred only on carbon surface with some ion conductivity (Nafion-Na +), it was possible to significantly reduce the thickness of ...

实验研究表明,与纯Nafion膜相比,Nafion/Ti3C2Tx复合膜的质子传导性明显增强。然而,由于实验手段的限制,Ti3C2Tx能够提高质子膜中质子传输的微观机制尚不清楚。因此,通过分子动力学模拟方法揭示水和水合氢离子在复合物膜中的静态和动态行为...
综上所述,为稳定锂硫电池使用中的锂金属阳极,制备了Nafion保护层。原位合成的Nafion保护层与锂金属形成共形结合,消除了LiPS与锂金属之间的寄生反应,提高了锂金属阳极的循环稳定性。因此,使用高硫负极和超薄锂金属阳极的Nafion保护层使Li-S全...
