Abstract

Different weight ratio of Si and polydopamine (PDA) has been employed for encapsulation of Si nanoparticles with PDA to buffer Si volume expansion and provide a pathway for Li ion transport. Si-C composite anodes have been developed and studied for Li-ion batteries (LIBs) by carrying out electrochemical characterization. The morphological properties of Si-C composites were also investigated. It was found that the 1:1Si to PDA weight ratio composite electrode led to high electrochemical performances. It delivered a high initial discharge capacity of 3451 mAhg⁻¹ at 0.05C and retained greater capacity at higher C-rate compared to other composites.
