3d tomography of li ion distribution in all-solid-state batteries

Can X-ray microscopy tomography reconstruct 3D morphology of all-solid-state lithium-ion battery electrode?

Soc.167 100558 In this study, a synchrotron transmission X-ray microscopy tomography system has been utilized to reconstruct the three-dimensional (3D) morphology of all-solid-state lithium-ion battery (ASSB) electrodes. The electrode was fabricated with a mixture of Li (Ni 1/3 Mn 1/3 Co 1/3)O 2, Li 1.3 Ti 1.7 Al 0.3 (PO 4) 3, and super-P.

Can neutron radiography visualize lithium ion transport in a solid-state battery?

In the present study, we have the demonstrated the utility of the radically different neutron absorption properties of the two predominantly occurring isotopes of lithium when used in conjunction with operando neutron radiography and in situ neutron tomography to visualize lithium ion transport during cycling of a solid-state Li–S battery.

Can a solid-state Li-s battery be enriched with a neutron absorbing 6 Li?

By enrichment of the Li–In anode of an all solid-state Li–S battery with highly neutron absorbing 6 Li we have shown that it is possible to visualize the diffusion of lithium ions from the anode through the solid electrolyte separator under electrochemical operation.

Can a solid electrolyte separator elucidate lithium ion transport pathways?

The elucidation of lithium ion transport pathways through a solid electrolyte separator is a vital step toward development of reliable, functional all-solid-state batteries.

Which 3D imaging techniques are used to study solid-state electrodes?

The use of 3D imaging techniques such as focused ion beam tomography (FIB), a destructive method, and X-ray micro-computed tomography (µCT), a non-destructive method, to study the microstructure of solid-state electrodes [27 - 29] and solid electrolyte (SE) interphases is well established.

Does 2D radiography provide a 3D distribution of Li in the cathode?

In this previous study, taking advantage of the highly neutron absorbing nature of Li, 2D radiography, performed operando, revealed a Li reaction front that progressed through the cathode as the cell was cycled while in situ tomography, provided the 3D distribution of Li in the cathode at different charge states.
