The Latin expression “ in situ ” literally means “in position”, and in battery research this refers to measurements that are performed on materials in their original position inside the device, i.e. without disassembling the battery. This allows characterization to take place under more realistic conditions, contrary to ex situ measurements.
In this review a comprehensive overview is given of recent in situ Li-ion battery research, in which techniques, cell design, as well as scientific results are described. The focus will be on recent developments and the challenges and requirements regarding the specially designed electrochemical cells. 2. X-ray techniques 2.1. X-ray diffraction
In this regard, in situ analysis techniques have made significant progress toward understanding the basic science of battery systems and finding better performance-improving factors.
The first in situ SEM for battery research was identified by Baudry et al. 271 They compared the morphological changes of FeS, TiS 2, and V 6 O 13 cathode materials in polymer lithium batteries. In another study, Orsini et al. 265 conducted SEM to study the cross-sections of plastic cells in a quasi in situ mode.
In this review, in-situ characterization techniques applied in secondary battery studies are discussed in three aspects, bulk materials, interface and gas reactions. Their differences as well as synergism are revealed. 1. Introduction
However, in order to conduct in situ experiments, batteries must be fully operational under the circumstances imposed by the diagnostic tool, which often demands specially designed devices and measurement setups, thereby hindering straightforward application of in situ techniques.
