The properties of battery materials have been well classified in the literature in an anatomical fashion, but systematic treatments of the composite battery electrode and complete storage device have been less rigorous. By understanding and compensating for certain material disadvantages through complete cell modification, we have preliminary evidence that the zinc alkaline system can meet grid scale requirements (for both cost and performance). We are now furthering these initial finding throughs the use of in situ mechanical testing and monitoring methods, where we hope to be able to better quantify battery failure modes. We are also exploring novel capacitors and power system designs which complement the aforementioned battery to further increase cycle life
Dan Steingart is an assistant professor in the department of chemical engineering at the City College of New York, a founding faculty member of the CUNY Energy Institute, and Director of the Kaylie Entrepreneurship Competition at CCNY. He has developed printing processes for electrochemical energy storage, distributed sensors for large scale electrochemical processes, and power conversion circuitry for wireless sensor nodes in both academic and industrial laboratories. As a co-founder of Wireless Industrial Technologies (WIT) he spent considerable time probing conductors carrying over 50 kA in commercial electrowinning plants while trying to remember what not to touch or breathe.
