Better batteries for electric cars and cellphones and better batteries for industrial use that can store excess power generated by wind and solar farms and then supply it to the grid at times of peak demand are greatly needed. The ability to efficiently store energy generated from renewable sources would quite literally be a game changer in the quest to build a clean energy future and reduce the impact of climate change. George Crabtree, director of the Joint Center for Energy Storage Research, discusses the importance of next-generation batteries with Paris Schutz on Chicago Tonight.

Seeing Battery Solutions Move to Assess the Health of Batteries
Organic redox-active molecules (redoxmers) are popular for flow battery fluids. Their structural variability comes with other properties that may be tailored for function. We discovered that fluorescence emission can be engineered into redoxmers, which allows real-time tracing of species crossover in a liquid flow cell, … Read More
