Dual-active Li‖Te–Bi liquid metal batteries with enhanced coulombic efficiency and cycling stability
Tellurium (Te), a chalcogenide with higher electrical conductivity than sulfur (S) and selenium (Se), can be made into liquid metal batteries with high energy density. The Te-Bi alloy positive electrode inhibits Te dissolution and enhances lithium diffusion, which further improves the coulombic efficiency and cycling stability of lithium batteries. Due to the dual-activity mechanism, Li‖Te<sub>5</sub>Bi<sub>5</sub> achieves ∼100% capacity utilization. Our results highlight a viable strategy for advancing high-voltage LMBs, providing an option for achieving long-life stationary energy storage solutions.
