The Effect of Solid Content on the Electrochemical Performance of Lithium Ion Battery Graphite Anode

Introduction

The lithium-ion battery (LIB) has become the primary power source for various portable electronic devices due to its high energy density, long shelf life, and environmentally friendly nature. One crucial component in lithium-ion batteries is the anode, which is typically made of commercial graphite. The performance of the anode plays a significant role in determining the overall efficiency of the battery. Therefore, optimizing the characteristics of the anode sheet is essential to improve battery performance.

The Importance of Anode in Lithium-Ion Batteries

The anode in lithium-ion batteries is responsible for storing lithium ions during the discharge process. The performance of the anode is influenced by various factors, including the type of material used, the thickness of the anode sheet, and the solvent used in the manufacturing process. In this study, we focus on the effect of variations in the solvent N, N Diethyl Acetamide (DMAC) and the solid content on the graphite anode sheet on battery performance.

Research Methods

This study employed various analytical techniques to examine the effect of solvent variations and solid content on the performance of graphite anode electrochemicals. These techniques include:
