Regression analysis of lithium-ion battery degradation data

The focus of this research is to carry out regression analysis to discover the factors that significantly contribute to the life cycle of the lithium-ion cells using the degradation data. The research was conducted by investigating the batchwise degradation model of these cells which concludes that the degradation of the cells starts slowly and accelerates later. This was followed by creating a regression model separately for one-stage and two-stage cells to identify the relation between the charging policy and the average life-cycle of these cells.
