DESCRIPTION:Dr. Gao Liu\, Senior Scientist and Group Leader of the Applied 
 Energy Materials Group at Lawrence Berkeley National Laboratory will give a
  seminar titled "Achieving Fast Ion Transport and High Ionic Conductivity i
 n Glassy Polymers Via Higher Order Molecular Structure Design" to the inter
 ested faculty and students at Discovery Park.\n\n \n\nAbstract\n\nMany comp
 onents inside of a lithium battery are soft materials\, providing important
  functions for its high performance and long lifetime. Electrode binders ar
 e an example of this soft material as a critical component of lithium-ion b
 atteries electrode. Our lab has conducted research on functional polymer bi
 nders for advanced battery for over a decade. In this presentation\, we wil
 l report our recent work to re-design multifunctional conductive polymers t
 o achieve both high electronic conductivity and ionic conductivity. In the 
 conventional design of conductive polymers\, organic functionalities are in
 troduced via bottom-up synthetic approaches to enhance specific properties 
 by modification of the individual polymers. Unfortunately\, the addition of
  functional groups leads to conflicting effects\, limiting their scaled syn
 thesis and broad applications. Here we show a conductive polymer with simpl
 e primary building blocks that can be thermally processed to develop hierar
 chically ordered structures (HOS) with well-defined ordered morphologies. O
 ur approach to constructing permanent HOS in conductive polymers leads to f
 ast ion-transport\, high ionic and electronic conductivity properties\, and
  mechanical robustness\, which are critical for many electrochemical applic
 ations. I will further discuss the variable structures of the polymers\, an
 d specific applications of this class of dual charge multifunctional polyme
 ric conductors for battery applications.\n\n \n\nBio\n\nDr. Gao Liu is a Se
 nior Scientist and Group Leader of the Applied Energy Materials Group at La
 wrence Berkeley National Laboratory\, a Fellow of the Electrochemical Socie
 ty and a Fellow of the Royal Society of Chemistry. Dr. Liu has over 20 year
 s of experience in developing materials and system engineering for electric
 al energy storage. Liu’s research combines synthetic chemistry\, composite 
 engineering and electrochemistry to solve interdisciplinary problems in ene
 rgy generation\, storage and usage. The Dr. Liu’s lab uses advanced diagnos
 tics to understand fundamental and critical issues in energy systems\, and 
 synthetic techniques to develop new materials that improve overall system p
 erformance. Dr. Liu pioneered the multifunctional conductive polymer adhesi
 ve research. Dr. Liu’s electrode binder research contributes to the fundame
 ntal understanding of behaviors of the polymeric binder in the composite el
 ectrode\, and leads to rational design of functional electrode binders for 
 new storage chemistries. Dr. Liu’s on-going researches in energy storage co
 ver electrode binder\, silicon\, sulfur and lithium metal materials\, elect
 rode engineering\, electrolytes and additives\, and solid-state conductors.
  Besides energy storage research\, Dr. Liu also performs materials and engi
 neering research in building resiliency\, circular economy\, and advanced m
 anufacturing. Dr. Liu has over 190 peer-reviewed publications and over 28 g
 ranted patents.
