Materials for Electrochemical Energy Storage in Brazilian Air Force

In the context of the 4th Industrial Revolution, paradigms are changing rapidly. Populations growexponentially and thus more and more needs for security, food, natural resources (especially water),electrical energy, mobility, health, sustainability, among others, are demanded. So, it's necessary todeepen concepts and develop technologies that can accommodate and integrate such aspects.

Recently, a lot of progress has been made in relation to energy matrices, mainly due to allegationsrelated to fossil matrices, said to contribute to some degree for the accumulation and transport ofheat outside of previous patterns in the biosphere. This strengthens the discussion about thegeneration, storage and use of energy. In this regard, Brazil has been privileged by its great water,biomass, solar and wind potential.

It provides the emergence of multiple business platforms aroundthese resources, with low environmental impact. Furthermore, with renewed strategic guidance inthis field and a very competitive availability of mineral resources with high added value for theseapplications. It includes reserves of graphite, niobium, rare earths and lithium, materials that haveattracted growing interest in this regard.

The needs of the electric aircraft market and their energyand power requirements are raised, and compared with storage devices already commercialized or inthe prototype phase. Using electrodes based on niobium, graphene and lithium MXenenanomaterials to the development of battery and supercapacitor packs, the aim is to disrupt theoperation of small mockups in order to have them for future eVTOL and UAV technologies, above thelimits of current devices.

The challenge surpasses the automotive one because there are several waysof transferring momentum. So, energy and power consumption can vary greatly depending on them(flat flight, takeoff, landing, angular turns, stall and others), in addition to subsystems containedtherein.
