Dual additives enabling high-performance solid polymer electrolytes for stable cycling of lithium metal batteries
CuF<sub>2</sub> and LiBOB were co-introduced into polycarbonate-based polymer electrolytes (PVT-CB) to overcome the trade-offs between ionic conduction and interfacial stability, resulting in improved ionic conductivity (8.4 × 10<sup>-4</sup> S cm<sup>-1</sup>) and enhanced electrochemical stability (5.04 V <i>vs.</i> Li/Li<sup>+</sup>). The resultant Li|PVT-CB|LCO cells show a boosting capacity retention of 88.8% after 250 cycles. The combination of CuF<sub>2</sub> and LiBOB not only facilitates efficient Li<sup>+</sup> transport but also enhances the stability of the electrolyte-electrode interface, making PVT-CB a promising candidate for high-performance, durable solid-state lithium metal batteries.
