Summary: |
In this project, we aim to make an integrated study of our recently patented glassy electrolytes in Li-batteries.
Specific challenge:
The electrification of road transport is a key to sustainable and environmentally friendly mobility of persons and goods, in particular for short-range transport and transport in urban areas. In order to reach this goal it is essential to develop improved cost-competitive and sustainable storage technologies for Electrified Vehicles (EV) achieving significantly enhanced performance with respect to current lithium-ion batteries (LIBs) technologies, to allow the production of EVs that more closely match the performance of existing internal combustion vehicles (e.g. and in particular considering the driving range). It is crucial for the Portuguese competitiveness that the next generation of batteries will be "made in Portugal," i.e., developed and produced in Portugal. Conversely, the knowledge and prototypes generated in this project will cover other kinds of applications, e.g., energy storage in electrical grids.
Scope:
To achieve progress well beyond current lithium-ion cell technologies, various key factors have to be improved at the same time, such as: energy density, power density, the ability to work under severe thermal conditions, charging speed, and inherent safety of the battery cells including crash and abuse conditions. In addition, the future battery has to have a competitive cost; it has also to be produced in an environmental friendly way, considering the availability of raw materials and the batteries' recycling potential, as well as a sound life cycle assessment. The scope may be reached by developing related specific new materials for electrolytes. In order to accelerate the industrial take-up of the proposed solution, the development of prototypes should be included to show clear progress beyond existing post lithium-ion technology in terms of durability, cyclability and energy density, wi  |

Significant improvements of the usability of EVs, with extended driving range and improved battery durability (recharging, cyclability and safety) obtainable at competitive costs. The energy density of the proposed new batteries should reach at least twice the energy density in comparison with the best in the class of the Li-Ion technology at the same power density.
Type of action:
We intend to study our recently patented [14Bra] glassy electrolyte Li3ClO based (obtained from an anti-perovskite crystalline material) [14Bra1] in LIBs technologies. To the best of our knowledge our glassy electrolytes present the highest ionic conductivity for the solids and most of the liquids (25 mS/cm) previously reported. Another fundamental property of the glassy electrolyte is its wide electrochemical window (8 V) that allows the use of all known pairs of batteries' electrodes. Furthermore, its high concentration of lithium ion promotes fastest kinetics and increased life-cycle, bringing batteries energy densities closer to their theoretical values. We want to incorporate the electrolyte into batteries that we will assembly with pouch cell dimensions (> = 2.5x2.5 cm2). We will use graphite/graphene/spongy carbon as negative electrodes and Lithium Nickel Manganese Cobalt (NMC) lamellar and spinodal as positive electrodes. |
