In J-PARC, we have constructed the energy-resolved neutron imaging system, named "RADEN", as the dedicated beamline for energy-dependent neutron imaging experiments. This instrument was designed to fully conduct Bragg edge imaging, neutron resonance absorption imaging and pulsed polarized neutron imaging together with the state-of-the-art conventional neutron imaging. RADEN is now used by users in various scientific and industrial fields. Especially industrial applications on the hydrogen fuel cells and Li ion batteries for the electric vehicles are intensively conducted to improve their performance due to the recent movement toward carbon neutrality. In this presentation, development of pulsed neutron imaging techniques at J-PARC will be introduced and results of application studies will be discussed.
