Abstract

Electrochemical reactions and ion exchange processes in Li-ion batteries not only depend on the properties of the electrode material and electrolyte, but also greatly depend on the geometric structure and size of the electrode. The distance between positive and negative current collector might have a significant effect. A battery with dimensions of 6x5 has the highest efficiency value in the 3rd cycle of 96.75657%, where two samples with larger dimensions have efficiency values below 80%. The maximum discharge capacity of the 6x5 sample is also the largest, namely 171.41829 mAh.g-1 with an rct value of 1.4675 Ω. Cyclic voltammetry test result also shows that NMC541-6x5 has the lowest potential difference (ΔE) which lead to better reversibility and kinetics of Li ions during charge transfer.
