This project area covers topics, such as standardized protocols for cell testing and diagnostic approaches to assess the quality of recovered material.that serve multiple projects within the ReCell Center.Taking advantage of well-established facilities across ReCell, this area uses cross-cutting capabilities to accelerate deployment of R&D results from individual tasks by industry.

The ReCell collaboration will focus on four key Crosscutting Efforts:

Cell Analysis, Modeling and Prototyping (CAMP) Facility

The CAMP Facility actively supports the efforts of the ReCell Center by providing baseline materials, fabricating trial electrodes and baseline electrodes, fabricating and testing numerous coin cells, and fabricating single-layer pouch cells. It has established a thorough test matrix and protocols to evaluate electrochemical performance of active materials of interest.

Post Test Facility

Post-test diagnostics of aged batteries can provide additional information regarding the cause of performance degradation, which previously could be only inferred. The facility combines microscopy, spectroscopy, and chromatography in a controlled-atmosphere glove box to characterize materials without air exposure. These results will help us identify issues in the recycled materials, such as effectiveness of different recycling processes in separating initial mixtures of cathode, anode, supporting foils, and casing materials.

Diagnostics of Aged Materials

This project aims to provide statistical distributions of structural change, composition, and morphology of aged electrode materials using electron backscatter diffraction (EBSD), which enables analysis of cathode materials at the primary particle level.

Microcalorimetry on Recycled Materials

Advanced energy storage devices are very sensitive to operating temperature, with high temperatures degrading them faster, and low temperatures reducing their power and capacity. The Thermal Test Facility (TTF) equipment can determine the impact of cell design on overall performance. It will use its isothermal calorimeters to develop an understanding of the life cycle effects on heat generation and determine whether recycling processes have deleterious effects on cell performance.
