DESCRIPTION:<i>(zoom lecture link comes shortly before)</i> Current state-o
 f-the-art lithium-ion batteries (LIBs) contain electrode materials with mo
 stly layered structures that serve as host lattices for the reversible\, e
 lectrochemical intercalation of lithium ions. The kinetics of these interc
 alation reactions are typically limited by the solid-state diffusion of th
 e ions inside the lattice. Volumetric changes that accompany the (de-)inse
 rtion of ions further lead to degradation of the electrode materials. Thes
 e factors contribute to the limited power and lifetime of LIBs. While some
  of these limitations can be mitigated by nanostructuring of the electrode
  material\, there is a large interest in finding structural motifs that al
 low for intrinsically fast ion diffusion with reduced host lattice deforma
 tion\, even in bulk-sized particles. In this presentation\, I will highlig
 ht how interlayer properties\, such as interlayer distance and interlayer 
 chemistry\, affect electrochemical ion intercalation processes in layered 
 host materials. It is demonstrated that the presence of interlayer structu
 ral molecules can increase the accessibility of intercalating ions to the 
 interlayer space and affect their transport properties. Increased interlay
 er spacing and reduced deformation during ion intercalation can lead to a 
 change from diffusion-limited to non-diffusion limited (or pseudocapacitiv
 e) charge storage behavior\, enabling favorable charge storage kinetics. T
 he talk will give an overview of my research group’s efforts to synthesi
 ze interlayer-functionalized layered and two-dimensional materials with ta
 ilored interlayer properties towards high power intercalation electrodes a
 nd highlight the challenges regarding both materials synthesis and charact
 erization.\nSpeaker: Dr. Simon Fleischmann
