Parallel-Connected Battery Current Imbalance Dynamics
Andrew Weng, Sravan Pannala, Jason B. Siegel +1
In this work, we derive analytical expressions governing state-of-charge and current imbalance dynamics for two parallel-connected batteries. The model, based on equivalent circuit…
Predicting the impact of formation protocols on battery lifetime immediately after manufacturing
Andrew Weng, Peyman Mohtat, Peter M. Attia +4
Increasing the speed of battery formation can significantly lower lithium-ion battery manufacturing costs. However, adopting faster formation protocols in practical manufacturing s…
A Fast Diagnostic to Inform Screening of Discarded or Retired Batteries
Joseph A. Drallmeier, Clement Wong, Charles E. Solbrig +2
With the increased pervasiveness of Lithium-ion batteries, there is growing concern for the amount of retired batteries that will be entering the waste stream. Although these batte…
"Knees" in lithium-ion battery aging trajectories
Peter M. Attia, Alexander Bills, Ferran Brosa Planella +14
Lithium-ion batteries can last many years but sometimes exhibit rapid, nonlinear degradation that severely limits battery lifetime. In this work, we review prior work on "knees" in…
