Lithium-ion batteries (LIBs) are the electrochemical energy storage technology of choice that dominated the market for a variety of applications, ranging from portable electronics to electric vehicles. When high-capacity cathode materials like LiNi0.8Co0.1Mn0.1O2 (NCM811) are employed, the high stress generated during electrochemical reactions disrupts the mechanical integrity of traditional binder systems, resulting in decreased cycle life of batteries. Herein, we present a comparative analysis of two different binding agents like polyvinylidene difluoride (PVdF) as a non-aqueous based binder and gelatin as an aqueous based binder for NCM811 as a potential next-generation cathode material. The impact of the binding agents on the electrode morphology and cycling performance has been investigated. |
