Energy storage technology is becoming more and more important in our lives. Energy storage devices are no longer just to provide power for electronics. They are especially important for electric vehicles and also used in the electric grids to stabilize the flow of electricity, especially as intermittent power sources such as solar and wind enter the network. The group led by the professor Jim P. Zheng has completed many research projects funded by NSF, DOE, DOD, NASA, and industries in the research and development of energy storage materials and devices including supercapacitors, lithium-ion and beyond lithium ion batteries, and fuel cells. Prof. Zheng also created the energy density theory of multiple energy storage systems, including supercapacitors, lithium-ion capacitors, lithium-air batteries, and pre-lithiated lithium-ion batteries.
