Abstract

The energy storage market, particularly batteries, has assumed a prominent role on the global stage in recent decades. This is due to the growing of renewable energy and the electrification of vehicle fleets around the world. Clean energy sources, such as wind and solar, require effective storage systems such as stationary batteries to ensure full use of the energy generated, thus forming networks known as smartgrids. In addition to playing a fundamental role in market sectors such as drones and portable electronic devices, batteries are increasingly gaining ground in the automotive industry, whose main global players are in the process of transitioning from fleets powered by fossil fuels to electrified fleets, meeting ambitious goals established by both the private sector and government policies. Given this situation, it is urgent for the battery industry to invest in technological innovation, with the aim of producing increasingly efficient and accessible devices, which offer greater autonomy and power. In this context, we present the proposal to develop a new electrode architecture for pouch-cell electrochemical cells, aiming for their application in lithium batteries. This architecture is composed of a new VNO (vanadium niobium oxide) anode and an LFP (lithiated iron phosphate) cathode. The new VNO material demonstrated superior storage capacity compared to currently available technologies, reaching up to 600 mAh/g under ideal conditions, in addition to showing good electrochemical stability. Furthermore, the material has promising feasibility in the reconditioning/recycling process after the end of its first useful life. In turn, LFP is produced from mining byproducts, which has a significant impact on the technology's carbon footprint, contributing to reducing the environmental impact of the material's production. This project aims to offer the national market products with greater added value, superior performance and lower environmental impact, contributing to reducing national technological dependence on strategic issues and strengthening the national innovation ecosystem.
