Case Studies
Innovate UK Funded Advanced Cell Test (ACT)
Cognition and Imperial College London collaborated on this Innovate UK funded project that started in October 2020 (currently at >600,000 hours cycling) and is still gathering data to compare traditional cycling methods with advanced test techniques to predict cell life and the critical rollover point where cell capacity collapses.
Experimental Chemistry Cell Characterisation
Cognition was asked to undertake a set of characterisation tests over 3 months to generate a dataset that could inform future development by the customer. Cells were an experimental Li-ion chemistry in a 21700 format.
