Ed Shaffer II
Bio
Dr. Ed Shaffer has spent the last 15 years focused on developing technology to accelerate adoption of much needed alternative energy systems. In 2009, he founded Advanced Battery Concepts, LLC that has commercialized ground-breaking, energy storage technology termed GreenSeal® which includes over 85 patents granted worldwide. Throughout his career, he has worked across a variety of advanced materials applications including advanced dielectrics for electronics, optical materials for displays, materials for energy storage and photovoltaics. He has held a variety of roles including new business development, global R&D manager and scientist. He received his PhD in Materials Science from MIT.
Energy storage projects, from residential to utility scale, are booming across the globe with greater than 23% annual growth rate projected through 2030. Lead-based energy storage systems offer many benefits including global, non-conflict supply chains; proven recyclability at > 95%; and exceptional safety due to the use of aqueous electrolytes. Unfortunately, lead energy storage solutions are only a small percentage of the market mostly due to high installation and levelised cost of stored electricity. These high costs are due to low cycle life, high cost to manufacture and poor round-trip efficiency. Bipolar architecture addresses these challenges and provides a pathway for lead-based energy storage systems to compete against other chemistries, namely lithium iron phosphate. In this paper, we present data on bipolar battery systems achieving 92% DC-DC round-trip-efficiency and detail how bipolar batteries can achieve 15 years of daily cycling. Based on the results we project that bipolar lead systems offer a safer, more sustainable and more affordable energy storage solution than current lithium-based products.
