Work Description

Title: UofM Pouch Cell Voltage and Expansion Cyclic Aging Dataset Open Access Deposited

Attribute Value
  • The expansion was measured using a displacement sensor (Keyence, Japan) mounted on the top plate. The dynamic testing was done using a battery cycler (Biologic, France). The temperature was measured using a K-type thermocouple (Omega, USA) placed on the surface of the battery. Voltage, current, and temperature data were recorded using the BT-Lab software. The expansion data was recorded using a LabView program.
  • The focus of this research effort is to systematically study the capability of aging diagnostics using cell expansion under variety of aging conditions and states. The data collection campaign is very important to cover various degradation modes to extract the degradation features that will be used to inform, parameterize, and validate the models developed earlier. In the data collection campaign, we are documenting the evolution of the electrical and mechanical characteristics and especially the reversible mechanical measurement. It is important to note that we collect data using newly developed fixtures that enables the simultaneous measurement of mechanical and electrical response under pseudo-constant pressure.
