Synthesis And Characterization of PVDF-LiBOB Electrolyte Membrane With ZrO2 As Additives

Abstract

The electrolyte membrane serves as ions medium transport and as a separator between the anode and cathode in lithium ion battery. The polymer used for the electrolyte membrane must have sufficiently high mechanical strength to endure the pressure between the anode and cathode, a thin size and has a chemical and thermal stability.Polymer electrolyte membrane of lithium bisoxalate Borate (LiBOB) salt with PVdF as matrix polymer and the additive namely ZrO 2 has been fabricated. The method used was a doctor blade. The concentration of the additive was varied. The membranes were characterized using FT-IR, XRD, SEM and EIS. XRD analysis showed that the crystallinity index increased by the addition of ZrO 2 . The presence of functional groups in between lithium salts and polymer interaction investigated by FTIR analysis. The morphology of the membrane surface was identified by SEM analysis. SEM image and mapping showed the morphology of the membrane have typical porous layer. The electrical conductivity increased by the additions of ZrO 2 .

“…Bahan-bahan aktif untuk katoda yang dikembangkan sendiri adalah LiFePO4 6,7,8,9) dan LiMnPO4 10) . Sementara itu, bahan aktif untuk anoda yang dikembangkan adalah Li4Ti5O12 11,12,13) , sedangkan bahan elektrolit yang dikembangkan adalah LiBOB 14,15,16,17) . Diantara berbagai material yang dikembangkan tersebut, pengembangan material LiFePO4 paling banyak melibatkan instansi riset dan juga industri.…”

“…Proses sintesisnya adalah pertama-tama cairan H2O2 ditambahkan pada bahan baku FeSO4.7H2O sambil diaduk sehingga terjadi reaksi (17) dilakukan untuk menghasilkan produk utama FePO4 dari FePO4.2H2O 23) . Sementara itu, hasil síntesis lain berupa Na2SO4.10H2O dapat diolah sebagai produk samping menjadi Na2SO4 melalui serangkaian proses pencucian dan kristalisasi 23) .…”
