Professional Experience

Dr. Flynn has over ten years R&D experience in the battery and energy storage field with emphasis in lithium-ion, nickel-zinc, silver/zinc, and semi fuel cell systems.Other areas of interest include solid-state research into novel electrochemical materials.After graduating from Boston College with a B.S. degree in chemistry, he entered graduate school at Tufts University and received a Ph.D. in Physical Chemistry.His graduate thesis was a study in the reduction of several phosphorous and ether compounds by sodium dissolved in liquid ammonia.While in graduate school he gained extensive experience in a range of analytical techniques, methods of handling air sensitive compounds, and became a skilled glass blower.

After receiving his doctorate, Dr. Flynn went onto conduct Air Force sponsored research on the lithium copper chloride sulfur dioxide rechargeable system.This research led to significant improvements in the rate capability and low temperature performance of the couple.Later Dr. Flynn accepted employment at Yardney Technical Products and was the Principal Investigator of an Air Force sponsored Phase II Program to develop a 20 Ahr lithium-ion prismatic cell for aerospace applications.This effort involved electrochemical evaluation of a range of carbon anode materials, high voltage lithium insertion compounds, and non-aqueous electrolytes.Other aspects of the program were concerned with cell design, hardware and packaging issues.The final outcome of the program was the delivery to the Air Force of five prototype 20 Ah cells with significantly improved performance.

After managing the Phase II program at Yardney to a successful completion, he accepted a research position at BST Systems where he designed and fabricated the company's first lithium-ion cell.At BST Systems, Dr. Flynn won funding from the US Department of Energy under the CARAT program to conduct material research on novel carbon fiber anode material for lithium-ion cells.He was also responsible in evaluating membrane separators for silver-zinc system.In addition, he studied novel additives to lower the rate of hydrogen evolution at the zinc electrode in alkaline electrolytes as less toxic replacements for mercury, lead, and cadmium.

Dr. Flynn has recently joined Phoenix Innovation and is responsible in developing Metal/Air systems incorporating Phoenix Innovation's patent polymer electrolyte technology.Other responsibilities include the synthesis and characterization of new polymers and SBIR proposal efforts.
