具有高能量密度的锂硫电池的成功设计具有挑战性的前景，可以显著推动汽车技术的发展。锂硫电池将使现有锂氧化物电池的能量密度增加两倍，并具有快速充放电循环的高可逆性和数千次循环的寿命。基于对具有用于电化学活性材料的纳米容器的新型阴极材料的详细研究，我们计划在微米和纳米尺度上开发分层结构的碳电极，从而实现高能量密度的Li-S电池。在我们的多学科联盟中，聚合物工程师将开发新的聚合物基阴极材料，电化学家将优化电化学性能，物理学家试图从实验和理论角度理解基本原理。通过与领先的电池生产公司的密切联系，介绍应用方面。新材料开发路线将与专用仪器相结合，以揭示不同层次的结构和电化学方面，绝对元素组成，深度分析和电子氧化态以及充电和放电的模拟。

The successful design of Li-S batteries with high energy density has the challenging perspective to significantly boost the development of environmently friendly automotive technology. Li-S batteries will triple the energy density of existing Li-oxide batteries combined with high reversibility of fast charging-discharging cycles and lifetime of thouthands of cycles. Based on detailed investigations of novel cathode materials with nano-containers for electrochemical active materials, we plan to develop hierarchically structured carbon electrodes on micro- and nano-scale leading to high-energy density Li-S batteries. In our multidisciplinary consortium polymer engineers will develop the new polymer-based cathode materials, electro-chemists will optimise the electrochemical performance and physicists try to understand basic principles both from experimental as well as from theoretical viewpoint. Application aspects will be introduced by close contact with a leading battery producing company. New materials development routes will be combined with dedicated instrumentation to reveal structural and electro-chemical aspects at different levels, absolute elemental composition, depth profiling and electronic oxidation states as well as simulation of charging and discharging.
