Li-ion battery (LIB) cathodes (LFP, NMC)

LFP offer lots of benefits compared to lead-acid batteries and other lithium batteries such as long life span, no maintenance, extremely safe, lightweight, improved discharge and charge efficiency. Also, high Nickel NMC and Mn-rich layered oxides are commercially the most interesting candidates for the premium LIB for electric vehicles. We directly collaborate with the many leading industry partners to commercialize the high-energy LIB.

We investigate Li ion insertion kinetics using various LIB cathode materials. The local current and lithium concentration within the individual battery active particles determines the local stress and cycle life. Our group develops state-of-art x-ray microscopy techniques to take the video of lithium movement at nanometer scale.
