So you’ve downloaded a .cif file. Congrats, you now own a cryptic text document that looks like someone’s cat walked across a keyboard.
The good news, you don’t need a PhD to make sense of it. You just need VESTA, a free crystal visualization tool, you can tell engineers made the website don’t come at me.
VESTA apparently stands for Visualization for Electronic and STructural Analysis and you can download it here. Warning: the UI looks like it time-traveled from Windows 95, but it works.
What is a .cif File Anyway?
A CIF, short for Crystallographic Information File, is basically the blueprint for a crystal structure. It lists the atoms, their positions, the symmetry rules, and all the other structural details that make your material behave the way it does. Without software, though, a CIF is just a wall of human-unfriendly coordinates.
This is where VESTA comes in. It lets you see the atoms instead of worshiping the matrix. Open the CIF, rotate the structure, repaint the atoms, and finally understand what’s happening inside your favorite cathode without a single crystallography course on your transcript.
Where to Get .cif Files
There are two solid free databases:
We have already done some of the work here for you if you’re looking for LCO, LFP, NMC, and sodium-ion options like Prussian White: here are the .cif files we have used
Some Resources We Love:
Alyssa read this book recently and it covered how important it is for amateurs to show up publicly and share their messy learnings- it felt like exactly what BBB embodies
