On the Efficiency of LFP Lithium-ion Batteries

Lithium-ion batteries are becoming more and more ubiquitous in many applications and appear as a key element for the success of energy transition. Their energy efficiency needs to be carefully understood and studied. In this work, we study the influence of the state of charge and of the shape of the current on the value of the efficiency of LFP (lithium-ion iron phosphate) lithium-ion cells. This is a preliminary step toward a full efficiency modeling.
