Battery Degradation Dataset (Fixed Current Profiles＆Arbitrary Uses Profiles)

77 nominally identical high-energy 18650 lithium-ion batteries are cycled with fixed or arbitrary uses current profiles. 22 batteries are cycled with fixed current profiles of charge current (1C, 2C, or 3C) and discharge current (1C, 2C, or 3C). 55 batteries are cycled with arbitrary uses profiles of charge current (obeys a uniform distribution among 1C, 2C, or 3C, and changes randomly every 5 cycles) and a specified discharge current (3C).

All the battery degradation tests were carried out by the Advanced Energy Storage and Application (AESA) Group at Beijing Institute of Technology.
