Thermally Controlled Dual Stabilization Mechanisms of Modified Kenaf-Derived Lignin-Based Aqueous Binders for Silicon Electrodes Used in Lithium-ion Batteries

Key Points

• The aim is to improve the stability of silicon electrodes in lithium-ion batteries using modified lignin-based binders.
• Developed thermally controlled dual stabilization mechanisms for lignin-based binders
• Tested the performance of silicon anodes with and without the modified binders
• Evaluated electrode degradation during charge-discharge cycling
• Silicon electrodes with modified lignin binders showed reduced degradation compared to conventional binders
• Thermal stabilization improved the cycling performance and longevity of the electrodes
• The volume expansion of silicon during cycling was better accommodated
