Data publication for "Feasibility of Na-Zn batteries for grid-scale energy storage: insights from in situ studies"

This dataset contains unprocessed results from the X-ray radiography imaging of high temperature molten salt Na-Zn battery.

The folders are structured as follows:

- 01 to 03 correspond to radiography results,

- 04 corresponds to comparison of long-term cycling of two different batteries.

01 to 03 has subfolder structure as follows:

- 01 has the raw files in 16bit tiff format,

- 02 has unprocessed png files with fixed contrast and overlay of cycling data for each time step,

- 03 is an mp4 video of png files made with ffmpeg,

- 04 is the recorded cycling data.

The raw data has the Date and time as title.

There is 167 second offset between radiographs and electrochemical data (one has to add the offset time to join both data sets).

Cycling data has been exported as .txt from EC-Lab V11.61 with following variables:

*time/s* *Ewe/V* *I/mA* *(Q-Q0)/mA.h* *cycle number* *mode* *ox/red*
