Rate testing step for organic cathode materials in aluminum ion batteries research

Latest updated: Mar 20, 2025
Video recording version: 8.0.0.516, compatible with BTS 8.0 software.

Open the preset rate test procedure and let the battery rest for 1 hour to stabilize its internal state.
Since the study was on cathode materials, the battery was charged first.
Setting the constant current charging step and selecting the C-rate mode.
The nominal specific capacity of the organic cathode material studied in this experiment is 515mAh/g, which can be found in reference.
Enter the actual mass of active material 2mg.
Because the aluminum chloride-based ionic liquid electrolyte used will decompose above 2.4V.
So set the charging cutoff voltage 2.3V.
Then set the constant-current discharge electrical step with a discharge cutoff voltage of 0.1V
Cycle start step is 2, cycle 10 times.
Set the rate gradient to 0.2C, 0.5C, 1C, 2C, 5C, 10C, 20C, 0.2C.
Setting multiple rate gradients allows for a more comprehensive evaluation of cell performance and electrode material properties at different rates.
Cycling 10 cycles at each magnification provides a relatively comprehensive assessment of battery performance, saving time and resources.
Rate parameters can be set according to your needs.
The above demo parameters are for reference only, please refer to your own experiments.
After setting the parameters of the work step, just click start.
