Aging Test - Cylindrical Cell - Part 01 - Single Cells

Test Sample Specifications Nominal Capacity = 3400 mAh Graphite / NCA 18650 Cell Cycling Protocol - Normal (N) Voltage Window Charge: CCCV at C/2 up to 4.2 V and a 50 mA cutoff current Discharge: CC at C/2 down to 2.7 V Cycling Protocol - Reduced (R) Voltage Window Charge: CCCV at C/2 up to 4.0 V and a 50 mA cutoff current Discharge: CC at C/2 down to 2.9 V Cycling Life Capacity fade and number of cycles are included in the filename. Example: File = 'Ba01_N20_OV1_300.xls' N20 = 20% Capacity fade under the normal voltage window Number of Cycles = 300
