- This paper presents a novel thin-film electrolyte of a 2:1 blend of polyetheramine (glyceryl poly(oxypropylene)) and cross-linked oligomeric poly(propylene oxide) diacrylate with LiTFSI. The polyetheramine acts as a surfactant, and can thereby be applied as a conformal coating on complex surfaces-here demonstrated for porous LiFePO4 cathodes-making it useful for 3D-microbatteries. The poly(propylene oxide) diacrylate blends with the surfactant and is easily UV cross-linked, thereby ensuring good mechanical stability. Electrolytes, ∼ 2 μm thick, were casted onto LiFePO 4 cathodes and cycled against metallic lithium, displaying stable discharge capacities of ∼ 8 mAh/g at room temperature and ∼ 120 mAh/g at 60 °C. The electrolyte showed conductivities of 3.45 × 10 - 6 and 5.80 × 10- 5 S cm- 1 at room temperature and 60 °C, respectively.
