Modeling the capacity degradation of LiFePO4/graphite batteries based on stress coupling analysis

Cycle ageing analysis of a LiFePO4/graphite cell with dynamic model validations: Towards realistic lifetime predictions

“…Cycle ageing was studied as a function of depth of discharge (DOD), current rate (C-rate) and Ahthroughput (the amount of charge received and delivered by the battery). LFP-based large size LIBs cycling ageing studies are various in the literature [8,19,24,33,34,36,42,44,57,58,66,69,72], but this one enhances the results by adding further steps of dynamic validation that do not focus on testing specific end-user profiles. Some of the LFP cells ageing studies took into account both calendar and cycling ageing [57,66,69,72].…”

Deterioration of lithium iron phosphate/graphite power batteries under high-rate discharge cycling

“…Although LiFePO 4 has a very stable structure, it has been indicated that the LiFePO 4 /graphite batteries still suffer from life and power decay during long time cycling [8][9][10][11]. Therefore, aging of this type of battery remains one of the biggest concerns of automakers and end customers.…”

A comparative study of commercial lithium ion battery cycle life in electric vehicle: Capacity loss estimation

“…N. Omar [21] introduces a complicated capacity loss model considering the influence of the working temperature, charge and discharge rate, depth of discharge. In our previous work [22], capacity loss model considering the temperature, charge and discharge rate, end of charge and discharge voltage is built. Though the aging mechanism is not considered, now the empirical models can be used to find the battery capacity loss under different cycling conditions and are easier to be applied in BMS for predicting the battery capacity M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 6 fades because fewer parameters are involved and the calculation would be simple.…”
