4D imaging of lithium-batteries using correlative neutron and X-ray tomography with a virtual unrolling technique

“…I n recent years, the advancement of X-ray computed tomography (CT) capabilities have facilitated a broadening of our understanding of battery materials and devices, with studies spanning multiple length scales, from nanometre to millimetre, and multiple time scales from kilohertz to microhertz 1 . These studies have collectively provided insight into the relationship between electrode microstructure and performance [2][3][4] , battery architecture, safety [5][6][7][8] and new battery materials [9][10][11] . While the majority of these studies have utilised X-ray CT, there is growing interest in the application of neutron imaging for battery applications; the complementarities of X-ray and neutron imaging, which are sensitive to electron and nuclear density, respectively, provide significant opportunities for correlative studies.…”

Electrodialytic processes in solid matrices. New insights into battery recycling. A review

“…The current gravimetric capacity (amount of lithium that can be stored per mass of anodic material) of graphite anodes is around 372 mAh g −1 . New anode materials such as lithium titanate (LiTi 5 O 12 ), carbon nanotubes or Al, Sn and Si compounds are being studied for use as alternative anodes . The aforementioned materials would increase the value of the waste of LIBs, involving a significant growth of the concern about recycling processes.…”
