'Nanoscoop' technology for high-power Li-ion batteries
A new type of nanomaterial developed by engineers at Rensselaer Polytechnic Institute could enable the next generation of high-power rechargeable lithium-ion (Li-ion) batteries.
The new material, dubbed a ’nanoscoop’ because its shape resembles a cone with a scoop of ice cream on top, can withstand extremely high rates of charge and discharge that would cause conventional electrodes used in today’s Li-ion batteries to rapidly deteriorate and fail. The nanoscoop’s success lies in its unique material composition, structure, and size.
The Rensselaer research team, led by Prof Nikhil Koratkar in the Department of Mechanical, Aerospace, and Nuclear Engineering, has demonstrated how the nanoscoop electrode could be charged and discharged at a rate 40 to 60 times faster than conventional battery anodes, while maintaining a comparable energy density.
