We review in situ neutron techniques for studying lithium ion batteries. Four neutron measurement techniques, neutron depth profiling (NDP), neutron reflectivity (NR), small angle neutron scattering (SANS), and neutron imaging (NI) are discussed in this chapter. They are used to quantify the real-time distribution and transport of Li in active battery components during the battery operation, and gain new insights in the function and failure of battery systems. We demonstrate that in situ neutron diagnoses offer new opportunities in better understanding the performance and lifetime of secondary batteries.
