报告摘要：
In this talk, we’ll discuss the cold sintering process and focus on its application to solid electrolytes.
Solid electrolytes are enabling materials for solid-state batteries. Solid electrolytes are of interest for safer and more reliable replacements to liquid electrolytes at a wide range of operating temperatures.
Using cold sintering, the solid electrolyte Li1+xAlxGe2-x(PO4)3(x= 0.50) was densified to around 80% theoretical density in minutes at 120oC and 400 MPa. In order to bridge ionically resistive grain boundaries, a 5 minute post-processing at 650oC was required. High volume fractions of ceramic electrolyte could be co-sintered with polymer. Up to 95 vol.% Li1.5Al0.5Ge1.5(PO4)3+5vol.%Poly (vinylidene fluoride hexafluoropropy- lene) composite electrolytes were cold sintered at 120oC to densities exceeding 85%. After soaking in 1 M LiPF6ethylene carbonate-dimethyl carbonate (50 EC:50 DMC vol.%), composite electrolyte ionic conductivities at 25oC reached 10-4 S/cm. Using cold sintering, processing and integration of solid electrolytes and other important technical ceramics may now be possible at polymer processing temperatures.
报告人简介：
Seth Berbano began working with Murata Electronics North America, Inc. 2.5 years ago after finishing his Ph.D. at Penn State University, co-advised by Profs. Clive Randall & Michael Lanagan. Seth was a summer intern at the Taiyo Yuden R&D Center in Takasaki, Japan in 2015. In May 2011, he graduated from Iowa State University with a B.S. in Materials Engineering summa cum laude and minor in Economics. At Iowa State, he worked in Prof. Steve W. Martin’s group. Supported by the NSF International Materials Institute for New Functionality in Glass, Seth completed summer research internships with Prof. Masahiro Tatsumisago’s group at Osaka Prefecture University, Japan (2009) and with Prof. Hyo-Jun Ahn’s group at Gyeongsang National University, South Korea (2010).
