Layered titanoniobates are a versatile class of layered oxide materials and due to high theoretical capacities have been investigated for use in lithium batteries. Unfortunately, bulk titanoniobates often suffer from poor cycling performance or long charge/discharge durations especially during early cycling. Traditionally the materials have been synthesized as nanosheets, nanofibers or nanoparticles in an attempt to mitigate this reducing the required diffusion length. Here we propose a different approach by intercalating 2-aminoterephthalic acid molecules into the layered titanoniobate, HTiNbO₅. This gives 2D ceramic nanosheets spaced apart with the organic species greatly increasing the available space for diffusion between layers. During initial electrochemical cycling of the intercalated material there is a significant reduction in the time taken for activation processes to complete when compared to the pure ceramic. This demonstrates how intercalation can be used to influence cycling behavior of bulk layered oxide ceramics.

层状钛酸铌酸盐是一类通用的层状氧化物材料，由于理论容量高，已研究用于锂电池。不幸的是，大量的钛钛酸酯经常遭受不良的循环性能或长的充电/放电持续时间的困扰，特别是在早期循环期间。传统上，已经将材料合成为纳米片，纳米纤维或纳米颗粒，以试图减轻这种减小所需的扩散长度的过程。在这里，我们提出了一种不同的方法，即将2-氨基对苯二甲酸分子插入层状的钛铌酸盐HTiNbO _5中。这使二维陶瓷纳米片与有机物间隔开，大大增加了层之间扩散的可用空间。与纯陶瓷相比，在插层材料的初始电化学循环过程中，活化过程完成所需的时间显着减少。这证明了如何使用插层来影响块状层状氧化物陶瓷的循环行为。
