UT researchers are leading the development of a broad range of battery chemistries and materials to specifically address the needs of key industries, such as transportation and defense. Design criteria include increased gravimetric and volumetric energy density, reduced weight, increased cycle life, increased power, use of sustainable materials and a view toward U.S. energy independence.
