Meeting future electrochemical energy storage requirements with heterogeneous nanostructured electrode materials

Researchers at the University of Maryland, led by Dr. Sang Bok Lee, have published a review of advanced heterogeneous nanostructured materials for use in future electrochemical energy storage systems in the RSC journal Chemical Communications.

Such materials, they note, are promising electrode materials due to their synergic properties arising from integrating multi-nanocomponents, each tailored to address a different demand (e.g., high energy density, high conductivity, and excellent mechanical stability).

...we discuss these heterogeneous nanomaterials based on their structural complexity: zero-dimensional (0-D) (e.g. core–shell nanoparticles), one-dimensional (1-D) (e.g. coaxial nanowires), two-dimensional (2-D) (e.g. graphene based composites), three-dimensional (3-D) (e.g. mesoporous carbon based composites) and the even more complex hierarchical 3-D nanostructured networks.

The authors propose a future 3-D heterogeneous nanostructure as a goal toward developing ideal nano-architectured electrodes for future electrochemical energy storage devices.

This is the challenge facing advanced battery mass production. Picking the best technologies could make or break many future manufacturers. Nano-structures may be the way to go, if mass production cost can be reduced enough.
