Development of analytical spectroscopy using super-soft X-ray

为了有效利用宝贵而有限的能源，改进锂离子电池是我们必须承担的紧迫任务之一。为此，收集有关电池组件材料的基本信息是非常重要的。本项目的目的是发展超软X射线能谱，以满足在Li-K边进行XAFS测量的要求。通过研制一种新型的超软XAS光束线，我们可以研究二次电池组件和其他样品中轻元素的电子态。

Improving the lithium-ion battery is one of the urgent tasks we must take in order to use the precious and limited amount of energy effectively. For such end it is very important to collect the basic information concerning the battery component materials. The purpose of this project is to develop the ultra-soft X-ray spectroscopy to meet such request as the XAFS measurements on Li K-edge. By developing a new ultra-soft XAS beamline we could study the electronic state of light elements in the secondary battery components and other samples.
