The Effect of Lifepo4 Cathode Thickness on the Variation of Composition and Thickness of the Mesocarbon Microbead (MCMB) Anode in the Lithium Ion Battery Capacity

Introduction

Lithium-ion batteries have become an essential component in modern technology, powering everything from smartphones to electric vehicles. The performance of these batteries is heavily dependent on the composition and thickness of the cathode and anode materials. In this study, we explore the effect of the thickness of the lifepo4 cathode on the variation of composition and thickness of the Mesocarbon Microbead (MCMB) anode on the lithium ion battery capacity.

Materials and Methods

The materials used in this study consist of lifepo4 powder as a cathode filler, MCMB as an anode filler, Super P as a carbon additive, PVDF as a matrix, and DMAC as a solvent. The composition of the lifepo4 cathode sheet consists of 85% lifepo4, 10% Super P, and 5% PVDF dissolved in DMAC, with a thickness that varies between 100 μm, 150 μm, and 300 μm. Meanwhile, the composition of the MCMB Anode sheet is the same as the lifepo4 cathode, but with a variety of thickness of 100 μm and 150 μm and composition variations of 85: 10: 5 and 80: 13: 7 with a thickness of 150 μm.

The process of making electrodes is carried out using the Doctor Blade-based Sheet Casting method. The battery cell assembly process uses the stacking method on the prismatic battery model. This battery uses 1m lipf6 liquid electrolyte and poliolefin separator. To analyze the crystal structure of the active material powder, the X-Ray Diffraction (XRD) method is used, while the surface morphology and particle size of the active ingredient powder and the lifepo4 cathode sheet are analyzed using Electron Microscopy (SEM) scanning. Surface morphology The electrode sheet is checked using an optical microscope, and the battery capacity is tested using the BST8-10A30V tool.

In addition, the composition variation in the MCMB anode shows that the composition of 80: 13: 7 has a higher specific capacity at a cathode thickness of 100 μm, 150 μm, and 300 μm, each records a specific capacity of 69.65 mAh/gr, 73, 61 mAh/gr, and 81.93 mAh/gr. Each battery tested shows efficiency above 98%.

In terms of MCMB anode thickness, 100 μm thickness shows a higher specific capacity at 100 μm cathode thickness, 150 μm, and 300 μm, with specific capacity of 79.10 mAh/gr, 82.54 mAh/gr, and 88 mAh/gr. Efficiency for each battery in this category is also recorded above 99%.
