Recharging lithium battery research with first-principles methods

Abstract

Energy storage is a critical hurdle to the success of many clean energy technologies. Batteries with high energy density, good safety, and low cost can enable more efficient vehicles with electrified drive trains, such as hybrid electric vehicles, electric vehicles, and plug-in hybrid electric vehicles. They can also provide energy storage for intermittent energy sources, such as wind and solar. Today, and for the foreseeable future, rechargeable lithium batteries deliver the highest energy per unit weight or volume at reasonable cost. Many of the important properties of battery materials can be calculated with first-principles methods, making lithium batteries fertile ground for computational materials design. In this article, we review the successes and opportunities in using first-principles computations in the battery field. We also highlight some technical challenges facing the accurate modeling of battery materials. © 2011 Materials Research Society.
