In this research, we synthesized a series of TiCT nanosheets with varying lateral dimensions and conducted a thorough investigation into the profound relationship between the electrochemical performance of TiCT materials and their lateral sizes. This study innovatively incorporates a clever combination of small-sized and large-sized TiCT nanosheets in the electrode preparation process. This strategy yields excellent results at low scan rates, with the fabricated electrode achieving a high volumetric capacitance of approximately 658 F/g. Even more remarkable is the fact that, even under extreme testing conditions where the scan rate surges to 10 V s, the electrode retains its capacitive characteristics robustly without any significant performance degradation. These outstanding characteristics underscore the exceptional ability of TiCT electrode materials to maintain high energy storage capacity during rapid charge-discharge cycles, holding significant importance for advancing the development of electrochemical energy storage devices with fast response times and high power densities.
在本研究中，我们合成了一系列具有不同横向尺寸的TiCT纳米片，并对TiCT材料的电化学性能与其横向尺寸之间的深层关系进行了深入研究。本研究创新性地在电极制备过程中巧妙地结合了小尺寸和大尺寸的TiCT纳米片。该策略在低扫描速率下产生了优异的结果，制备的电极实现了约658 F/g的高体积电容。更值得注意的是，即使在扫描速率飙升至10 V/s的极端测试条件下，电极仍能稳健地保持其电容特性，而没有任何明显的性能下降。这些突出特性突显了TiCT电极材料在快速充放电循环中保持高能量存储容量的卓越能力，这对于推动具有快速响应时间和高功率密度的电化学储能装置的发展具有重要意义。
