Accelerating Rate Calorimetry Tests of Lithium-Ion Cells Before and After Storage Degradation at High Temperature

Some of the conditions that we test include:

  • ARC testing battery refers to a type of test conducted on batteries to determine their safety and performance in extreme conditions such as high temperatures, high humidity, and vibration. ARC stands for "abuse reaction cell," and this type of testing is designed to simulate real-world abuse that a battery might experience during its lifetime.
  • During ARC testing, batteries are subjected to a variety of abusive conditions, including overcharging, puncturing, crushing, and short-circuiting. The purpose of this testing is to identify potential safety hazards and to ensure that the battery can withstand abuse without causing a fire or explosion.
  • ARC testing is an important part of the battery development process, as it helps to ensure that batteries are safe and reliable under a wide range of conditions. It is particularly important for batteries used in high-risk applications, such as those used in aerospace, defense, and medical devices.
