Abstract
The transition from conventional vehicles to electric vehicles is caused by the increase in greenhouse gas emissions contributed by burning fossil fuels in conventional vehicles. As electric storage, lithium-ion batteries are used in electric vehicles. In this paper, the cathode material battery of LiCoO2 and LiNi1Mn1Co1O2 were fabricated and characterized. The characterizations of Fourier Transform Infrared (FTIR), X-ray diffraction (XRD), scanning electron microscope-energy dispersive X-ray (SEM-EDX), and Charge-Discharge (CD) were conducted to examine functional groups, material crystallinity, morphology, composition, and capacity of the LiCoO2 and LiNi1Mn1Co1O2 batteries. The results of FTIR indicate the battery contains oxalate. XRD results show a curve with narrow and sharp peak indicating the battery has high crystallinity. LiCoO2 composition is form of O, and Co with even distribution and radius in the range of 2 – 5 μm. For LiNi1Mn1Co1O2 is form of N, Mn and Co with atomic composition ratio of N : Mn : Co close to 1:1:1 and range of radius 30-40 μm. The specific capacity of LiCoO2 batteries is kept as 105.73 mAh/g and 291.05 mAh/g for LiNi1Mn1Co1O2 batteries.
