Abstract:
Developing new materials for Li-ion and Na-ion batteries is a high priority in materials science. Such development always includes performance tests and scientific research. Synchrotron radiation techniques provide unique abilities to study batteries. Electrochemical cell design should be optimized for synchrotron studies without losing electrochemical performance. Such design should also be compatible with operando measurement, which is the most appropriate approach to study batteries and provides the most reliable results. The more experimental setups a cell can be adjusted for, the easier and faster the experiments are to carry out and the more reliable the results will be. This requires optimization of window materials and sizes, cell topology, pressure distribution on electrodes etc. to reach a higher efficiency of measurement without losing stability and reproducibility in electrochemical cycling. Here, we present a cell design optimized for nuclear resonance techniques, tested using nuclear forward scattering, synchrotron Mössbauer source and nuclear inelastic scattering.
摘要:
开发锂离子和钠离子电池的新材料是材料科学的重中之重。这种发展总是包括性能测试和科学研究。同步辐射技术提供了研究电池的独特能力。电化学电池设计应针对同步加速器研究进行优化,而不会损失电化学性能。这种设计也应与操作测量兼容,这是研究电池的最合适方法,并提供最可靠的结果。细胞可以调整的实验设置越多,实验越容易,越快,结果越可靠。这需要优化窗户材料和尺寸,细胞拓扑,电极等上的压力分布.达到更高的测量效率,而不会失去电化学循环中的稳定性和可重复性。这里,我们提出了一种针对核磁共振技术优化的细胞设计,使用核前向散射进行测试,同步加速器穆斯堡尔源和核非弹性散射。
