Abstract

original image

In situ neutron depth profiling (NDP) offers the possibility to observe lithium transport inside micro-batteries during battery operation. It is demonstrated that NDP results are consistent with the results of electrochemical measurements, and that the use of an enriched 6LiCoO2 cathode offers more insight in transport processes occurring inside all-solid-state thin-film batteries.
