Lithium-sulfur (Li–S) batteries present a great potential to displace current energy storage chemistries thanks to their energy density that goes far beyond conventional batteries. To promote the development of greener Li–S batteries, closing the existing gap between the quantification of the potential environmental impacts associated with Li–S cathodes and their performance is required. Herein we show a comparative analysis of the life cycle environmental impacts of five Li–S battery cathodes with high sulfur loadings (1.5–15 mg·cm
−2
) through life cycle assessment (LCA) methodology and cradle-to-gate boundary. Depending on the selected battery, the environmental impact can be reduced by a factor up to 5. LCA results from Li–S batteries are compared with the conventional lithium ion battery from Ecoinvent 3.6 database, showing a decreased environmental impact per kWh of storage capacity. A predominant role of the electrolyte on the environmental burdens associated with the use of Li–S batteries was also found. Sensitivity analysis shows that the specific impacts can be reduced by up to 70% by limiting the amount of used electrolyte. Overall, this manuscript emphasizes the potential of Li–S technology to develop environmentally benign batteries aimed at replacing existing energy storage systems.
El presente artículo tiene como principal objetivo analizar desde un punto de vista teórico la triple dimensión que supone la inclusión completa de las Tecnologías de la Información y la Comunicación (TIC) en el currículo educativo. La primera de las dimensiones hace referencia a la inclusión de las tic como herramientas didácticas para el apoyo del ejercicio docente. La segunda alude a su integración como medida de fomento de un uso eficiente de las mismas. Desde la tercera, se sugiere la inclusión de las TIC como objetos de análisis crítico y de conocimiento. Las dos últimas dimensiones señaladas, las más olvidadas aunque no por ello las menos importantes, resultan fundamentales de cara a la promoción de ciudadanos críticos capaces de tomar decisiones razonables e informadas en lo que respecta a la evaluación, diseño, control e implementación de las nuevas tecnologías.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
