A Positron Implantation Profile Estimation Approach for the PALS Study of Battery Materials

Condensed Matter, 2023
Positron annihilation spectroscopy is a powerful probe to investigate the interfaces in materials relevant for energy storage such as Li-ion batteries. The key to the interpretation of the results is the positron implantation profile, which is a spatial ...
