ABSTRAKDewasa ini, pengembangan baterai sebagai bahan penyimpan energi yang
tinggi, ringan, mampu pakai dalam jangka waktu yang lama, telah banyak
dilakukan . Baterai berbasis ion lithium mampu menghasilkan energi yang besar,
dan reservoir ion lithium pada baterai adalah elektroda. Pada penelitian ini
elektroda yang dikembangkan adalah partikel nano LiCoO2 ditambahkan 5, 10,
15, 20 % v/v PVDF, sintesa partikel nano LiCoO2 dilakukan menggunakan teknik
planetary milling dan ultra sonic. Partikel nano LiCoO2 + x PVDF, dikarakterisasi
menggunakan SEM-EDX, XRD, TEM, PSA dan analisa konduktifitas.
Pembentukan lapisan tipis katoda, Pt/np-LiCoO2+xPVDF/Pt dilakukan
menggunakan metoda magnetron sputter deposition (MSD). Baterai mikro
Si/Pt/LiCoO2/C6/Cu hasil pembentukan MSD dianalisa menggunakan metode
SEM-EDX, XRD, analisa konduktifitas, Four Probe Analyzer. Hasil penelitian
menunjukan bahwa, nano partikel LiCoO2 + 10 %v/v PVDF memiliki
konduktifitas terbaik, memiliki struktur rhombohedral R-3m, dengan parameter
kissi a = b = 2,8213 Å, c = 14,0446 Å. Lapisan tipis Pt/np-
LiCoO2+10%v/vPVDF/Pt dibentuk menggunakan metoda MSD pada arus 20 A
dengan tegangan 0,7 kV, ditumbuhkan pada substrat Si(111), dimana partikel np-
LiCoO2+10%v/vPVDF membentuk morphologi ekuaksial. Perlakuan anil pada
temperatur 600oC selama 1 jam pada lapisan tipis Pt/np-LiCoO2+10%v/vPVDF/Pt
menunjukan bahwa butir kristal np-LiCoO2+10%v/vPVDF tumbuh dengan pada
orientasi [107]. Lapisan tipis np-LiCoO2+10%v/vPVDF pada sistem lapisan
Pt/np-LiCoO2+10%v/vPVDF/Pt, memiliki impendansi, kapasitansi dan
konduktansi yang relatif baik.
