提出了一种利用优化的类固体电解质的新型硅硫锂电池。该电解质是通过将醚基液体电解质与抑制穿梭效应的SiO2空心纳米球层和优化阳极固体电解质界面的氟碳酸乙烯添加剂集成而成的。制备的硅硫锂电池具有循环寿命长、可燃性低、抗短路恢复能力强等特点。
Anovel lithiated Si-S battery exploiting an optimized solid-like electrolyte is presented. This electrolyte is fabricated by integrating ether-based liquid electrolyte with SiO2 hollow nanosphere layer to suppress the shuttle effect and fluoroethylene carbonate additive to optimize the anodic solid electrolyte interface. The prepared lithiated Si-S batteries exhibit enhanced cycle life, low flammability, and strong recovery ability against short-circuit.
