Electrochemical cycling of an MJ1 18650 LG Chem Li-ion battery.
Achieved using a Maccor 4200 (Maccor Inc. U.S.A.).
Charging at a constant current of 1.5 A until 4.2 V
Then the voltage was held until the current reached 100 mA.
Discharging was performed at 4.0 A to 2.5 V.
This protocol was followed for 400 cycles.
All cycling was performed within an environmental chamber set to 24 °C.
