摘要

Dimethoxy Ethane (DME)-based electrolytes have emerged as promising alternatives to traditional sodium perchlorate (NaClO4) electrolytes in sodium-ion battery (SIB) technology, offering superior safety profiles without compromising performance or efficiency. In this research article, we investigate the optimization of SIB performance, safety and efficiency through the utilization of DME-based electrolytes supplemented with additives. Our study focuses on enhancing the performance of NVPF/HC full cells by incorporating additives into a base electrolyte of 1 M NaPF6 in DME. Electrochemical evaluations of these cells demonstrate significant improvements in key performance metrics, including capacity retention, cycling stability and rate capability. The cell with 1 M NaPF6 in DME shows 92.6% of initial Coulombic efficiency (ICE) for the NVPF half-cell and 87.69% for the Hard carbon half-cell. The cyclic stability for both the NVPF and hard carbon half-cells are 94% when cycled at 1C-2C rate for 100 cycles. For the full cell with NVPF cathode and hard carbon anode, the ICE is 80.3% with cyclic stability of 92% when cycled for 200 cycles at 1C-2C rate. Overall, this research highlights the transformative potential of DME-based electrolytes and additive formulations in revolutionizing SIB technology, offering a pathway towards safer, more efficient and more reliable energy storage solutions for a wide range of applications.
