Abstract


Membran elektrolit polimer pada baterai litium ion berfungsi sebagai media transport ion dan sebagai separator antara anoda dan katoda. Dalam penelitian ini, telah dilakukan sintesis membran elektrolit polimer LiBOB (Lithium Bis Oksalato Borate dengan rumus kimia LiB(C2O4)2) dengan menggunakan Polyvilinidine fluoride (PVdF) sebagai matriks dan bahan aditif  Zirkonium Oksida (ZrO2). Metoda yang dipergunakan adalah solution cast. Konsentrasi bahan aditif dibuat bervariasi. Membran yang terbentuk dikarakterisasi morfologi permukaan menggunakan Scanning Electrone Microscope (SEM), sifat elektrokimia dengan Cyclic Voltametric (CV) dan kapasitas baterai dengan kurva charge discharge. Hasil penelitian menunjukkan bahwa morfologi permukaan rantai polimer saling berikatan dan tersusun dengan bagus. Pori tertutup oleh rantai polimer secara rata yang berikatan membentuk jaring dan saling bertumpukan pada keadaan amorf. Terjadi reaksi oksidasi dan reduksi pada sel baterai dengan kapasitas charge sekitar 24 mAh pada tegangan 4 volt, sedangkan kapasitas discharge bernilai sama sekitar 24 mAh pada tegangan 4 volt dengan penambahan 10% ZrO2.
