Abstract

Lithium-ion battery is a type of rechargeable battery. A lithium-ion battery consists of several components, such as electrodes (anode and cathode), separators, and electrolytes. One factor that can affect a battery's performance is the quality of the electrodes. The commonly used anode consists of graphite powder. Currently, there is nanotechnology, namely the application of technology to make materials on the nanoscale (1-100 nm). The advantage of nanoparticle technology is its openness to be combined with other technologies, opening up opportunities to produce more perfect delivery systems. In this research, the production of lithium-ion batteries was carried out by adding nanoparticles as an anode. The nanoparticles used result from arc discharge synthesis with varying currents of 40A and 70A. The test results show that current variations in the arc-discharge synthesis process in the manufacture of lithium-ion battery anode nanoparticles affect the performance of lithium-ion batteries. Batteries using 70A nanoparticle anodes have a higher specific capacity than batteries using 40A nanoparticle anodes during chargedischarge. However, the specific capacity of the battery with nanoparticle anode is lower than that of the battery with graphite anode. When charging, the time needed for a battery that uses a 70A nanoparticle anode is shorter than a battery that uses a graphite anode and 40A nanoparticles. When discharging a battery that uses a 40A nanoparticle anode has a shorter time compared to a battery that uses a 70A nanoparticle and graphite anode.
