Large-Scale Energy Storage

Zinc-based batteries have gained serious traction in stationary storage providing high power back up power in critical infrastructure and long duration energy storage to support the grid. This presentation will share the cutting-edge research of the DOE funded HIDEZ national consortium to further zinc-based battery technologies leveraging support from industry to drive innovation.

There's no such thing as a 100% safe battery. But everyone wants a safer battery. If the cost is too high, then safety engineering is handled on systems basis, which can also be an expensive proposition. This presentation is an analysis of how much money can be saved on safety engineering if the battery cell is inherently safer. It will explore where cost savings can be found in ESS systems when safety can be re-engineered thanks to a safer cell. The presentation will also show Mana's approach to battery safety, including safety test results.

Most public Li-ion battery studies have aged cells only to 80% remaining capacity due to historical thresholds from the automotive industry. However, depending on the application requirements, batteries may still have significant value beyond this point. This presentation will cover the effect of temperature, state-of-charge range, and discharge rate on capacity retention, energy throughput, and round-trip efficiency of commercial LFP, NCA, and NMC cells in an 8+ year cycling study.
