Rational design of pre-intercalation electrodes for rechargeable battery
Liqiang Mai
Wuhan University of Technology, China
Rational design of the morphology and complementary compounding of electrode materials have contributed
substantially to improving battery performance, yet the capabilities of conventional electrode materials have
remained limited in some key parameters including energy and power density, cycling stability etc., because of their
intrinsic properties, especially the restricted thermodynamics of reactions and the inherent slow diffusion dynamics
induced by the crystal structures. In contrast, pre-intercalation of ions or molecules into the crystal structure
with/without further lattice reconstruction could provide fundamental optimizations to overcome these intrinsic
limitations. In this report, we discuss the essential optimization mechanisms of pre-intercalation in improving
electronic conductivity and ionic diffusion, inhibiting “lattice breathing” and screening the carriers charge. We also
summarize the current challenges in pre-intercalation and offer insights on future opportunities for the rational
design of pre-intercalation electrodes in next-generation rechargeable batteries.
