The ever-increasing demands for energy coupled with the decline in fossil fuels make advances in energy storage capability of paramount importance. The use of batteries to store electrical energy is becoming increasingly widespread. However, their current and predicted future use is presenting new challenges due to imitations in battery performance and scarcity of materials. It is therefore vital that next generation energy storage materials for batteries are developed to circumvent these issues.We propose to deliver (iso)alloxazine derivatives as tuneable organic energy storage materials. Organic materials have been much less widely investigated than inorganic systems, and our proposed use of these bio-inspired organic materials with their convenient chemical synthesis, tuneable redox properties and ability to bind to multiple Li-ions of the electrolyte are attractive systems for development. More specifically, we aim to embed the (iso)alloxazine units in porous architectures for incorporation as electrodes for advanced Li- and Na-ion batteries. The expectation is that the juxtaposition of these high-performance environmentally benign materials within porous and self-healing architectures will provide new electrodes with optimised energy density and sustained cyclability.

对能源的不断增长的需求加上化石燃料的下降使得储能能力的提高至关重要。电池存储电能的使用越来越普遍。但是，由于电池性能和材料稀缺的模仿，他们目前和预测的未来使用正在提出新的挑战。因此，至关重要的是要开发用于绕过这些问题的下一代电池储能材料。我们建议将（ISO）同嗪衍生物作为可调的有机储能材料传递（ISO）同嗪衍生物。有机材料的研究比无机系统少得多，并且我们提出的这些生物启发的有机材料及其及其方便的化学合成，可调的氧化还原特性以及与电解质多个液体结合的能力是有吸引力的开发系统。更具体地说，我们的目标是将（ISO）甲状酸嗪单元嵌入多孔体系结构中，以掺入高级Li-和Na-ion电池的电极。期望这些高性能在多孔和自我修复体系结构中的环境良性材料的并置将为具有优化的能量密度和持续环的新电极提供。
