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 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.
Numerous analytical methods have been developed to investigate the complex nature of battery reactions, but most of these were “ex situ” techniques that analyzed objects of interest outside their operating environment in the early days.
As a valuable method capable of uncovering the hidden keys to battery systems, in situ / operando imaging techniques are expected to drive the advancement of post Li-ion battery systems.
In situ TEM setups for battery studies are usually sealed liquid cell or open cell configurations. The liquid cell is used in the researches of liquid electrolyte based batteries, while the open cell plays a vital role in studying solid batteries. The key components for an open cell include a cathode, an anode, and an inorganic solid electrolyte.
