One of modern day’s objectives is to reduce the consumption of fossil fuels, which is partially done by replacing combustion engines in transport by electric engines. To foster the electrification of transportation, light batteries with high energy density are required. Essential ingredients of a battery are the electrolyte and the electrodes, the latter usually being a layered crystalline solid. Batteries charge and discharge by intercalating and removing alkali metal ions from the electrodes. Cyclically inserting and removing an ion into a layered material can disrupt this material or induce other structural defects over time. Thus, part of testing a new electrode material can be running it for many cycles under observation by X-ray diffraction. Standard coin cells are an excellent model system for battery research.
STOE offers two types of battery cell holders, one for coin cells and one for pouch cells.
Coin Cell Holder
The STOE coin cell sample holder offers to simultaneously measure powder X-ray diffraction as well as charge and discharge cycles with a connected potentiostat. Measurement data can conveniently be displayed in the accompanying WinXPow software in 3D plots, facilitating the visibility of any changes in the electrode materials.
- Standard CR2032 coin cell
- Fits into a standard STOE transmission sample holder
- Slewing motion to improve counting statistics
- Two pole contact to connect to a potentiostat
Pouch Cell Holder
STOE’s pouch cell holder allows to mount pouch cells on the diffractometer, simply by clamping them into position. The tabs are still accessible, so that measurements can be conducted in static state or in-operando when connecting a potentiostat. These datasets can be treated in the WinXPow software as described above.
- For big cells up to 120 x 160 mm
- 50 mm window diameter
- z-translation for precise positioning
