Prospective Life Cycle Assessment of a Model Magnesium Battery

Energy-storage systems are considered as a key technology for energy and mobility transition. Because traditional batteries have many drawbacks, there are tremendous efforts to develop so-called postlithium systems. The magnesium-sulfur (MgS) battery emerges as one alternative. Previous studies of Mg-S batteries have addressed the environmental footprint of its production. However, the potential impacts of the use-phase are not considered yet, due to its premature stage of development. Herein, a first prospective look at the potential environmental performance of a theoretical Mg-S battery for different use-phase applications is given to fill this gap. By means of the life cycle assessment (LCA) methodology, an analysis of different scenarios and a comparison with other well-established technologies are conducted. The results suggest that the environmental footprint of the Mg-S is comparable with that of the commercially available counterparts and potentially outperforms them in several impact categories. However, this can only be achieved if a series of technical challenges are first overcome

Índice de Posición Topográfica (TPI) para identificar áreas inundables y zonificación de especies vegetales en un manglar del Pacífico Sur de Nicaragua

El COP7 reconoció que los manglares son ecosistemas vulnerables y amenazados por la pérdida y la degradación del hábitat, que necesitan acciones urgentes para garantizar su conservación y uso racional. Los procesos geomorfológicos e hidrológicos son claves para el crecimiento y desarrollo de los bosques de mangle. Sin embargo, muy pocos estudios al respecto existen en Centroamérica. Los bosques de manglar ofrecen valiosos servicios económicos y ecológicos, como turismo y albergue de especies de flora y fauna. Además, protegen ante el incremento del nivel del mar causado por el cambio climático. La hidrología del manglar del Río Ostional, en el Pacífico Sur de Nicaragua, ha sido estudiado en años recientes sugiriendo una relación entre las especies de mangle y los aportes de agua dulce. En este proyecto, se exploró el uso del Índice de Posición Topográfica (TPI) para identificar zonas inundables a pequeña escala y con poca variación de elevación en un manglar. Para ello se realizó una caracterización geomorfológica mediante el levantamiento topográfico a detalle de la zona y análisis del TPI como método de clasificación de formas del terreno para identificar las zonas de inundación; así como el levantamiento de zonificación de especies vegetales. La clasificación del TPI fue relacionada a la zonificación de especies. Esta relación permitirá identificar las zonas más sensibles a modificaciones geomorfológicas de posible origen antrópico, lo cual es un insumo esencial para la gestión integral del bosque

Water‐Soluble Inorganic Binders for Lithium‐Ion and Sodium‐Ion Batteries

Inorganic materials form an emerging class of water-soluble binders for battery applications. Their favourable physicochemical properties, such as intrinsic ionic conductivity, high thermal stability (>1000 °C), and compatibility to coat a diverse range of electrode materials make them useful binders for lithium-ion and sodium-ion batteries. Li and Na containing phosphates and silicates are attractive choices as multifunctional inorganic aqueous binders (IABs). This review discusses these binders\u27 structural, thermal, and ionic properties, followed by exploiting their ionically conducting nature for all-solid-state batteries. Subsequently, the application of these compounds as binders and surface coating agents for different anodes and cathodes in lithium-ion and sodium-ion batteries is discussed. Eventually, a first evaluation of their environmental impacts and economic aspects is presented as well

Dataset of propylene carbonate based liquid electrolyte mixtures for sodium-ion cells

In this manuscript, we present rheology, ionic conductivity, density, chromatography, and life cycle analysis data on the PC+X electrolyte system with and without LiClO4. In particular, the data are presented in contact with Na surfaces. In this case, photographic images of electrolyte-sodium mixtures are also shown. The data was analyzed using OriginPro software to visualize it in an appropriate manner. In our view, the data serve as comparative values, form a basis of a chromatography analysis and are also valuable for modeling. The analysis of the data is presented in the manuscript “Comprehensive characterization of propylene carbonate based liquid electrolyte mixtures for sodium-ion cells

Toward the Potential Scale-Up of Sn0.9_{0.9}Mn0.1_{0.1}O2_{2}||LiNi0.6_{0.6}Mn0.2_{0.2}Co0.2_{0.2}O2_{2} Li-Ion Batteries – Powering a RemoteControlled Vehicle and Life Cycle Assessment

Academic research in the battery field frequently remains limited to small coin or pouch cells, especially for new materials that are still rather far from commercialization, which renders a meaningful evaluation at an early stage of development challenging. Here, the realization of large lab-scale pouch cells comprising Sn$_{0.9}$Mn$_{0.1}$O$_{2}$ (SMO), prepared via an easily scalable hydrothermal synthesis method, as an alternative active material for the negative electrode and LiNi$_{0.6}$Mn$_{0.2}$Co$_{0.2}$O$_{2}$ (NMC$_{622}$) as a commercially available active material for the positive electrode is reported. Nine double-layer pouch cells are connected in series and parallel, suitable for powering a remote-controlled vehicle. Subsequently, these SMO‖NMC$_{622}$ cells are critically evaluated by means of an early-stage life cycle assessment and compared to graphite‖NMC$_{622}$ cells, in order to get first insights into the potential advantages and challenges of such lithium-ion chemistry

La imagen y la narrativa como herramientas para el abordaje psicosocial en escenarios de violencia. Departamento Santander y Boyacá.

La imagen y la narrativa como herramientas para el abordaje psicosocial en escenarios de violencia. Departamento Santander y Boyacá.El diplomado en “Acompañamiento Psicosocial en Escenarios de Violencia” brinda herramientas estratégicas, teóricas, metodológicas y conceptuales, para el acompañamiento psicosocial en distintos escenarios de crisis y violencias a las que se ve expuesta una persona, grupo, o comunidad, desde la comprensión de las subjetividades como fuentes de memoria y acción transformadora. Dado lo anterior, se realiza el análisis de los relatos tomados del libro “Voces. Relatos de violencia y esperanza en Colombia” seleccionando el caso de José Ignacio Medina, que desde la lógica narrativa se realiza un análisis, brindando información sobre la violencia e injusticia. Así mismo, se aborda el caso de las comunidades de Cacarica, generando reflexiones colaborativas y estrategias de acompañamiento psicosocial. A través de las contribuciones realizadas por el grupo, se logra plasmar un aprendizaje significativo en; subjetividad, fotovoz, narrativa, voces, significados, procesos de resiliencia, interpretación, análisis y construcción de preguntas reflexivas, estratégicas y circulares, que tienen como fin orientar al profesional de psicología en la organización de intervenciones psicosociales, direccionadas a velar por la salud mental individual y colectiva de las personas, que se encuentran en situaciones de crisis o violencia. Palabras claves: Violencia, Victimas, Subjetividad, Acompañamiento psicosocial, Enfoque narrativo, Relatos.This certification program on Psychosocial Accompaniment in Violent Scenarios brings conceptual, methodologic, theory and strategic tools for the psychosocial accompaniment in different situations of violence and crisis to which either a person, group or community can be exposed. With this in mind, a meticulous analysis on the stories from the book ‘Voices, Stories of violence and hope in Colombia’ was conducted. One of the sample cases selected belongs to José Ignacio Medina, which from a logic- narrative approach analysis, brings significant data about violence and injustice. The case of ‘Cacarica communities’ is studied in the same way coming up with collaborative reflections besides new psychosocial accompaniment strategies. Thanks to the contributions made by the attendees, significant learning is gained in topics like: subjectivity, narrative photovoice, voices, meanings, resilience processes, interpretation, analysis and reflective, strategic and circular question making that can guide the professional in psychology to organize psychosocial interventions in order to safeguard the mental health of both individuals and collectives that face violence and crisis. Key words: Violence, victims, subjectivity, social accompaniment, narrative approach, storie
