Pembuatan Baterai Lithium Menggunakan Bahan Aktif Mesocarbon Microbead (Mcmb) sebagai Anoda dengan Variasi Persentase Berat Pelarut N,N-Dimethyl Acetamide (Dmac)

Abstract

Preparation anode lithium ion battery using Mesocarbon Microbead (MCMB) as an active material had been done with variation on the weight fraction of N,N Dimethyl Acetamide (DMAC) solvent by 42,85%, 33,3%, 27,27% against the active material to see the battery performance by comparing battery made by MCMB powder heat treat 5000 C with MCMB powder without treatment. Battery performance testing using a Charge-discharge test and Cyclic voltamettry (CV). Preparation of sheet battery using MCMB as an anode active material, Polynilidene Flouride (PVDF) as a binder and Acetylenene Black (AB) as an additive. The result obtained MCMB powder without treat has a hexagonal crystal structur with graphite composition has not been 100%. The particle morphology is meeting with diameter range of 106 μm. The most well anode sheet resulting from mixing with 33,33% weight fraction DMAC with MCMB powder without treat. Charge-discharge test result show the maximum charge capacity is by 3,32 mAh and discharge capacity is 1,63 mAh with spesific capacity is 20,12 mAh/g.
