Despite their potential as post lithium-ion batteries, solid-state Li-metal batteries are struggling with insufficient electrochemical sustainability and ambient operation limitations. These challenges mainly stem from lack of reliable solid-state electrolytes. Here, a new class of single-ion conducting quasi-solid-state soft electrolyte (SICSE) for semi-solid Li-metal batteries (SSLMBs) is demonstrated. Rheology-tuned SICSE pastes, in combination with UV curing-assisted multistage printing, allow fabrication of seamlessly integrated SSLMBs without undergoing high-pressure/high-temperature manufacturing steps. The single-ion conducting capability of the SICSE plays a viable role in stabilizing the interfaces with the electrodes. The resulting SSLMB full cell exhibits stable cycling performance and bipolar configurations with tunable voltages and high energy densities under ambient conditions, along with low-temperature performance, mechanical foldability, and nonflammability. |
