Analysis of Lithium-Ion Battery Cycle Degradation Using DRT Method
Electrochemical Impedance Spectroscopy (EIS) can be used to analyze the internal electrochemical processes of lithium-ion batteries. The data is generally fitted using an Equivalent Circuit Model (ECM) to extract parameters related to specific electrochemical processes. Due to the difficulty in separating various electrochemical processes in EIS, the Distribution of Relaxation Times (DRT) method has been … Read more
