Executive summary:
Scalable Ultra-Power Electric-vehicle Batteries (SUPErB). Combining the power and cycle-life benefits of a supercapacitor with the energy benefits of a Li-ion cell.
One of the challenges for electric vehicles is to meet peak power requirements. Existing high-peak-power devices, such as supercapacitors, suffer from low energy densities and the SUPErB project aims to lift this limitation using advanced electrode materials and Li-ion battery engineering. The ultrahigh- power cells for electric vehicle batteries that the SUPErB project will develop will have very high peak power handling capability and the SUPErB project will demonstrate, for the first time, 10 kW.kg-1 and 40 Wh.kg-1 at the cell level. This will enable improved peak-power handling in EV main traction batteries. Spin-off applications are numerous with the technology finding use in fast charge stations and transport, UPS and military applications.
