The testing method is the only way to check and observe the battery performance related to lithium-ion activities. It is essential to understand how those ions work during charge and discharge in the structure of electrode and electrolyte. This is a part of comprehensive research on battery component that will figure out the high-performance target of rechargeable battery. In elucidating this basic science, neutron scattering is very important. The International Conference on Battery for Renewable Energy and Electric Vehicles (ICB-REV 2021) also covered this topic with Prof. Takashi Kamiyama as distinguished keynote speaker. Professor Takashi, who is a senior researcher in Spallation Neutron Source China, explained about the role of Neutron Probe for Battery Development.
Briefly, neutron as characterization probe of materials and devices, has three effect; transmitted (for knowing material structure information), resonance (gamma ray that gives the composition), and scattering (elastic scattering for atomic to nano-size information and inelastic scattering for spectroscopy). Professor Takashi also gave several information about the other utility of Neutron Probe in his facility. Such as Imaging function which could unfold the density of crystalline materials from Bragg Edge. The other things like Diffusion coefficient by QENS (Quasi-elastic neutron scattering), Surface structure by reflectometer, and SANS (Small Angle Neutron Scattering) also covered.
