Using Battery Explorer API and getting the related CIFs

Hi!
I was able to get a list of all the battery materials IDs using
mpr._make_request(’/battery/all_ids’)
Now I’m getting the information for each battery by
mpr.get_battery_data(battery_id)
But the resulted dictionary doesn’t contain the CIF file.

What is the best way to get the CIF file given the battery ID?

I’m changing the battery ids, like mp-1176474_Li to mp-1176474 and then mpr.get_data(‘mp-1176474’) but this method doesn’t work for like half of the battery materials.
Thank you
