发布时间:2019年03月29日

各部门、各单位:  

按应我校邀请,村田电子北美公司Seth Berbano教授将于43日来我校作学术报告,具体安排如下:  

报告题目:Cold Sintering Process (CSP): Mechanisms,    

              Challenges, Opportunities, and Applications  

报 告 人:Seth BerbanoMurata Electronics North America, Inc  

报告时间:201943日(星期三)10: 00  

报告地点:理学院418会议室  

报告摘要:  

In this talk, well 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 120 oC and 400 MPa. In order to bridge ionically resistive grain boundaries, a 5 minute post-processing at 650 oC 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 120 oC to densities exceeding 85%. After soaking in 1 M LiPF6 ethylene carbonate-dimethyl carbonate (50 EC:50 DMC vol.%), composite electrolyte ionic conductivities at 25 oC 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. Martins group. Supported by the NSF International Materials Institute for New Functionality in Glass, Seth completed summer research internships with Prof. Masahiro Tatsumisagos group at Osaka Prefecture University, Japan (2009) and with Prof. Hyo-Jun Ahns group at Gyeongsang National University, South Korea (2010).
