Fabricated samples without and with the MYLER® films

• Ni-foam with acrylic and steel base/substrate

• Empty: acrylic and steel base/substrate  

Samples on Left are without and Right are with MYLER film 

Results:

• XRD patterns of Ni foam and empty sample holder; with and without MYLER® film 

• XRD patterns of air-sensitive Li foil; with and without MYLER® film 

Conclusions:

• The air-sensitive samples can be characterized by using this simple and cost-effective method.
• The MYLER® film shows it fingerprint in resulting X-ray pattern at around 2θ = 26-27°
• Intensity of peaks is observed to decrease for the cases of film covered sample holders.
• Wrinkles on surface of film during the crimping of cell for air-tightness, may lead strange results
