From consumer electronics to automotive applications, the advancement and deployment of fast charge capable energy storage supports a combination of absolute customer need in some cases, with product differentiation and real or perceived customer desire in others. At the same time, potential near- and far-term advancements toward achieving higher energy density, greater sustainability, and lower cost simultaneously present a direct technical counter-challenge to fast charge advancement in many cases. Between energy storage for consumer electronics and energy storage for automotive, there is both common ground and differences in terms of the seeming counterbalance of the challenges of fast charge advancement with those of energy density increase and other desired energy storage improvements.

This presentation will discuss fast charge issues and progress among applications and will describe future energy density advancement and other trends which may add significant challenge along the way. Methods which may potentially provide partial relief from these challenges, and which may transcend the counterbalancing effect, will be described.
