Electrolyte variations used in LiSnO2/LiFePO4 battery are LiCl and NaNO3 with 2 types of solvents namely H2O and DMSO. This research aims to analyze the results of characterization of LiSnO2/LiFePO4 electrodes and the effect of electrolytes and solvents on the performance of lithium ion battery with LiSnO2/LiFePO4 electrodes. The results of electrode characterization using SEM show that LiSnO2 …
Autonomous vehicle is a technology that uses a self-driving system. Self-driving is a type of autonomous car control that functions to make it easier for humans to drive automatically without driver intervention. One of the important things in a self-driving system is the movement of the car. One of the movements of a self-driving car is automatic reverse movement. In this research, the automat…
