Abstract

New technological market demands have led to a race against time to develop the highest performance energy storage devices. Supercapacitors are highlighted in terms of high charge storage capacity, long life cycles and fast energy availability, and can be applied to electronic circuits, energy redundancy systems, in hybrid systems with batteries, among others. And lithium-ion batteries dominate the portable electronics market and meet the high demand of the second largest electric power consumption market, which is hybrid and all-electric vehicles with a projected US$ 73 billion by 2025 of batteries. The development of these supercapacitors and batteries is highlighted by new technologies, including new materials to achieve the highest electrochemical performance and ensure long device operating cycles. New 2D materials have as a recent discovery the MXenes, materials of ceramic nature, have high mechanical and chemical stability, in addition to conductivity and high energy storage capacity. They are compounds obtained from alloys of transition metals with carbon, and/or nitrogen and surface elements (O, OH, F), capable of facilitating the transport of small ions in their structure. In order to obtain new technologies for energy storage and supercapacitor devices for lithium-ion battery anodes, this project proposes the development and characterization of MXenes (Nb2CTx/La) anode semi-cells. In order to obtain a more stable structure in the ion intercalation process and higher conductivity for better performance in charge storage, fast charge and greater charge retention in long cycles.
