Topology optimization of 3D flow fields for flow batteries

Autor: Lin, Tiras Y., Baker, Sarah E., Duoss, Eric B., Beck, Victor A.

As power generated from renewables becomes more readily available, the need for power-efficient energy storage devices, such as redox flow batteries, becomes critical for successful integration of renewables into the electrical grid. An important com
