Due to easy synthesis, low cost, low toxicity, and high capacity, iron oxides nanomaterials and derived compounds are particularly promising regarding their potential for energy storage in Li- and Na-ion batteries. We hence propose to study the growth mechanisms and synthesis routes as well as the structural, magnetic, and electrochemical properties of Fe2O3-based carbon nanocomposites. This will be achieved by combining the competences of the host team, i.e. condensed matter physics and materials science including a battery laboratory, and of Dr. Zakharova, who is an internationally renowned inorganic chemist with great experience in synthesis of oxide nanostructures. In particular, we will study in detail the effect of structure, morphology, and particle size of the iron oxide nanocomposites on their physical and electrochemical properties. Particular emphasis will be put on improving the material aiming at a novel anode material with a good cycling stability and discharge capacity. The main scientific aims are (1) to gain fundamental understanding of growth mechanisms and synthesis routes, and (2) to search for anode material of Li- and Na-ion batteries with a good cycling stability and discharge capacity.

由于易于合成，低成本，低毒性和高容量，因此铁氧化铁纳米材料和衍生化合物对于它们在Li-和Na-ion电池中储存的潜力尤其有希望。因此，我们建议研究基于FE2O3的碳纳米复合材料的生长机制和合成途径以及结构，磁性和电化学性质。这将通过结合主持人团队的能力，即包括电池实验室在内的凝结物理和材料科学的能力，以及扎卡罗娃博士的扎卡罗娃博士，后者是一位具有国际知名的无机化学家，在合成氧化物纳米结构方面具有丰富的经验。特别是，我们将详细研究氧化铁纳米复合材料的结构，形态和粒径对其物理和电化学性质的影响。特别强调将改善针对具有良好骑自行车稳定性和排放能力的新型阳极材料的材料。主要的科学目的是（1）获得对生长机制和合成途径的基本理解，以及（2）搜索具有良好循环稳定性和放电能力的Li-和Na-ion电池的阳极材料。
