Synthetic Control Across Length-scales for Advancing Rechargeables (SCALAR)

A US Department of Energy Energy Frontier Research Center (Class: 2018 — 2022)


To design materials, interfaces, and architectures that revolutionize the performance of energy storage systems by dramatically expanding the range of materials systems and chemistries that can be employed in next generation batteries.

Research Plan

The SCALAR center aims to rethink battery materials to take advantage of a much broader set of reactions and materials than traditional transition metal cation redox approaches. This is combined with new methods to control and characterize architectures and interfaces with the goal of bridging atomistic and nanometer length-scales in the quest to improve cycling stability and electron and ion transport over broad working ranges.
