Lithium-O2 batteries represent one of the most appealing candidates for battery elec. vehicles because of their remarkable theor. high energy d., similar to fossil fuels. Solid polymer electrolytes represent a plausible solution to tackle some of the challenges associated with conventional liquid-based Li-O2 batteries, including safety concerns. Herein, cross-linked robust gel polymer electrolytes (GPEs) based on poly(ethylene glycol) dimethacrylate and tetraethylene glycol di-Me ether as a plasticizer are prepared by rapid UV-photopolymerization Both types of robust GPEs presented high ionic conductivity at room temperature (1.6 x 10-4 and 1.4 x 10-3 Sè·¯cm-1 for single ion or dual ion, resp.). Both types of GPEs, single-ion and dual-ion lithium conductors, have been compared for the first time on Li-O2 cells. First, their performance was investigated in sym. Li|Li cells. In this case, the dual-ion GPE showed outstanding behavior where the overpotential was <0.2 V vs. Li0/Li+ for more than 40 h at a c.d. as high as å? mAè·¯cm-2. On the other hand, in the full Li-O2 configuration, the single-ion GPE cell showed superior discharge capacity, up to 2.38 mAè·¯hè·¯cm-2. Here, a dynamic discharge characterization technique is proposed as a method for evaluating the polarization effect in electrolytes during discharge in an easy, quantifiable, and reproducible manner. ACS Applied Energy Materials published new progress about Photopolymerization. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Quality Control of 112-63-0.
