Ion conductive membranes (ICMs) with highly conductive proton selectivity are of significant importance and greatly desired for energy storage devices. However, it is extremely challenging to construct fast proton-selective transport channels in ICMs. Herein, a membrane with highly conductive proton selectivity was fabricated by incorporating porous carbon sieving nanospheres with a hollow structure (HCSNs) in a polymer matrix. Due to the precise ion sieving ability of the microporous carbon shells and the fast proton transport through their accessible internal cavities, this advanced membrane presented a proton conductivity (0.084 S·cm−1) superior to those of a commercial Nafion 212 (N212) membrane (0.033 S·cm−1) and a pure polymer membrane (0.049 S·cm−1). The corresponding proton selectivity of the membrane (6.68 × 105 S·min·cm−3) was found to be enhanced by about 5.9-fold and 4.3-fold, respectively, compared with those of the N212 membrane (1.13 × 105 S·min·cm−3) and the pure membrane (1.56 × 105 S·min·cm−3). Low-field nuclear magnetic resonance (LF-NMR) clearly revealed the fast proton-selective transport channels enabled by the HCSNs in the polymeric membrane. The proposed membrane exhibited an outstanding energy efficiency (EE) of 84% and long-term stability over 1400 cycles with a 0.065% capacity decay per cycle at 120 mA·cm−2 in a typical vanadium flow battery (VFB) system.

通过传统瓷砖制备工艺的干压法,制备了一种碳化酚醛树脂基导电陶瓷复合材料(CCC)。首先,将导电前驱体溶液(酚醛树脂)与陶瓷前驱体均匀混合,随后在单次热处理中同时实现了碳化和陶瓷化。碳化后的材料赋予复合材料出色的电导率和可靠的循环加热特性。在12 V电压下通电10 min 后材料表面温度可达386 ℃,在20 V电压下达到400 ℃仅需48 s。红外热像图表明,热量在复合材料表面分布均匀,并且可以通过更改电路布置(串联或并联)来调节电热转换性能。此外,与普通陶瓷相比,导电陶瓷复合材料在8.2 GHz下表现出了26.2 dB的优异电磁屏蔽性能,并提升了光热转换性能。更重要的是,这种单次热处理加热生产导电陶瓷复合材料的方法成本较低,可在原有瓷砖生产线的基础上进行大规模生产。出色的电学性能促进了该陶瓷复合材料在焦耳加热(如除冰、烧水和烹饪)及电磁屏蔽中的应用。
