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.

对能源的需求不断增加，加上化石燃料的减少，使能源储存能力的进步至关重要。使用电池来存储电能正变得越来越普遍。然而，由于电池性能的模仿和材料的稀缺，它们目前和预测的未来使用提出了新的挑战。因此，至关重要的是，下一代电池储能材料的开发，以规避这些问题。我们建议提供（异）咯嗪衍生物作为可调的有机储能材料。有机材料的研究远不如无机系统广泛，我们提出使用这些生物启发的有机材料，其方便的化学合成，可调的氧化还原性能和结合到电解质的多个Li离子的能力是有吸引力的系统。更具体地说，我们的目标是将（异）咯嗪单元嵌入多孔结构中，以作为先进的锂离子和钠离子电池的电极。期望这些高性能环保材料在多孔和自我修复结构中的并列将提供具有优化能量密度和持续循环能力的新电极。
