Kathryn Rice Bullock was a chemist, best known for her work in developing valve-regulated lead-acid batteries. Her theoretical and statistical modeling of the electrochemistry of batteries led to better understanding of processes such as corrosion and advances in battery design. Her work has applications for hybrid and electric cars, residential fuel cell systems and solar energy storage. Kathryn Bullock has published over 60 technical papers and holds at least 11 U.S. patents. She served as vice-president of the Electrochemical Society in 1992 and as president from 1995 to 1996.
