Evaluation of Anode Composition in Lithium-Ion Batteries

Abstract

A lithium-ion battery is a rechargeable battery with excellent energy, high power, high theoretical capacity, economics, reasonable cycle rate, good stability, high-temperature resistance, and environmentally friendly. An anode is one of the main components of a lithium-ion battery. The most frequently used as an anode material is graphite. Graphite has good structure stability, excellent electrical conductivity, good cycle life and economics, high intercalation-deintercalation, high voltage, and energy efficiency. Another material that can be used as the anode component is SiO2. In this study, we evaluate the anode composition with the dependent variables of active material and binder. Moreover, the structures of samples were characterized by X-Ray diffraction measurement, and the electrochemical performances were tested by galvanostatic charge-discharge. The anode material was applied directly in a 18650 cylindrical cell and graphite with a mass composition of 90% exhibit the best performance with a specific discharge capacity of 367.44 mAh/g (at 0,1C) and coulombic efficiency of 92%.
