ABSTRACT

The lithium-ion battery has been utilized in various fields including energy storage system, portable electronic devices and electric vehicles due to their high energy and power densities, low self-discharge, and long cycle-life performances. However, despite of various research on electrode materials, there is a lack of research on developing of binder to replace conventional polymer-based binding materials. In this work, petroleum pitch (MP-50)/polymer (polyurethane, PU) composite binder for lithium-ion battery has fabricated not only to use as a binding material, but also to re-place conventional polymer-based binder. The MP-50/PU composite binder has also prepared to various ratios between petroleum pitch and polymer to optimize the physical and electro-chemical performance of the lithium-ion battery based on the MP-50/PU composite binder. The physical and electrochemical performances of the MP-50/PU composite binder-based lithium-ion battery were evaluated using a universal testing machine (UTM), charge/discharge test. As a result, lithium-ion battery based on the MP-50/PU composite (5:5, mass ratio) binder showed optimized performances with 1.53 gf mm−1 of adhesion strength, 341 mAh g−1 of specific discharge capacity and 99.5% of ICE value.
