    A High-Rerformance Battery for Renewable Energy Storage

    A low-cost, high-performance battery chemistry developed by CU Boulder researchers could one day lead to scalable grid-level storage for wind and solar energy that could help electrical utilities reduce their dependency on fossil fuels. The new innovation, described today in the journal Joule, outlines two aqueous flow batteries, also known as redox flow batteries, which use chromium and organic binding agents to achieve exceptional voltage and high efficiencies. The components are abundant in nature, offering future promise for cost-effective manufacturing.

    1. We're excited to report some of highest performing battery chemistries ever, beyond previous limits.
    2. There are mismatches between supply and demand on the energy grid during the day.
    3. The basic problem with lithium ion batteries is that they don't scale very well.
    4. The size is less of an issue for grid-scale systems, because it would just be attached to an already large structure.
    5. Some people have taken this approach before, but hadn't paid enough attention to the binding agents.
    6. We got this to work at the relatively neutral pH of 9, unlike other batteries which use highly corrosive acid that's difficult to work with and difficult to dispose of responsibly.
    7. You could order 15 tons of these materials tomorrow if you wanted, because there are existing factories already producing them.
    8. We've solved the problem on a fundamental level.
