[ABSTRAK

Dewasa 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.

ABSTRAK

Nowadays, battery as a high energy storage, which is lightweight and

capable of use in a long period of time, has been developed. Lithium ion battery is

well known, where lithium ion is capable to produce large energy and electrode is

used as reservoir of lithium ions. In this study, nano particle of LiCoO2 added

with 5, 10, 15, and 20% of PVDF have been developed. nano particle of LiCoO2

was synthesized by using planetary milling and ultra sonic methods. Nano particle

LiCoO2 + xPVDF was characterized by using SEM-EDX, XRD, TEM, PSA and

conductivity analysis. The formation of micro battery was carried out by using

magnetron sputter deposition (MSD) method. Micro battery of

Si/Pt/LiCoO2/C6/Cu resulted from MSD was analyzed by using SEM-EDX,

XRD, conductivity analysis, and Four Probe Analyzer. The results showed that

nano particle of LiCoO2 + 10% v/v PVDF has the best conductivity, belong to the

structure of rhombohedral with space group R-3m, with lattice parameter a = b =

2.8213 Å, c = 14.0446 Å. Thin film of Pt/np-LiCoO2+10%v/vPVDF/Pt system

have been formed successfully at a current of 20 A and potential of 0.7 kV, on

Si(111) substrate, where particle of np-LiCoO2+10%v/vPVDF formed an equaxial

morphology. Annealing of Pt/np-LiCoO2+10%v/vPVDF/Pt at 600oC for 1 hour

resulted in the growth of np-LiCoO2+10%v/vPVDF crystal grain at orientation of

[107]. Thin film of np-LiCoO2+10%v/vPVDF on the system of Pt/np-

LiCoO2+10%v/vPVDF/Pt showed fairly good impedance, capacitance and

conductivity., Nowadays, battery as a high energy storage, which is lightweight and
