From: A locally solvent-tethered polymer electrolyte for long-life lithium metal batteries
a Rate performance of the Li | |SPAN coin cells. b Cycling stability of the Li | |SPAN coin cells at 1 C with a sulfur loading of 1 mg cm−2. c DRT analyses of Li | |SPAN coin cells in the first 5 cycles. d Comprehensive comparison of polymer-based ssLSBs performance (including specific capacity, areal capacity, and cyclability) between this work and those in previous reports. e Temperature-dependent performance of Li | |SPAN coin cells at 0.05 C. Values are means, and error bars were calculated by taking the standard errors from one sample for five measurements. f Charge-discharge profiles of the Li|LPE@Ni-DMF | SPAN pouch cell at 0.1 C with a sulfur loading of 2 mg cm−2. g Cycling stability of the Li|LPE@Ni-DMF | SPAN pouch cell with 50 mg sulfur and capacity of 47 mAh. The inset is the showcase of the solid-state Li-Sulfur pouch cell. All the coin cells and pouch cells were tested in the voltage range from 1 to 3 V.
