Lithium-ion batteries exhibit a well-known trade-off between energy and power, which is problematic for electric vehicles which require both high energy during discharge (high driving range) and high power during charge (fast-charge capability).
The energy available during the discharge of an EV battery determines the driving range. High volumetric and gravimetric energy densities are therefore important properties of lithium-ion batteries. Using our models, we are able to quantify these values as a function of electrode thickness and cell temperature.
Conclusive summary and perspective Lithium-ion batteries are considered to remain the battery technology of choice for the near-to mid-term future and it is anticipated that significant to substantial further improvement is possible.
1. Introduction Among numerous forms of energy storage devices, lithium-ion batteries (LIBs) have been widely accepted due to their high energy density, high power density, low self-discharge, long life and not having memory effect , .
This paper describes the experimental dataset of lithium-ion battery cells subjected to a typical electric vehicle discharge profile and periodically characterized through diagnostic tests. Data were collected at the Stanford Energy Control Laboratory, at Stanford University.
In fact, compared to other emerging battery technologies, lithium-ion batteries have the great advantage of being commercialized already, allowing for at least a rough estimation of what might be possible at the cell level when reporting the performance of new cell components in lab-scale devices.
