The project main goal is to develop new generation batteries for battery storage with a modular technology, suitable for different applications and fulfilling the increasing need of decentralised energy production and supply for private households and industrial robotised devices.. New materials and components will be developed and optimised to achieve longer lifetime (up to 10,000 cycles depending on the material selected), lower costs (down to 0.03 €/kWh/cycle), improved safety and more efficient recycling (>50%). The expected results will strengthen EU competitiveness in advanced materials and nanotechnologies and the related battery storage value chain, preparing European industry to be competitive in these new markets. This will be achieved by using high capacity anodes coupled with cobalt free cathode and with a very safe gel polymer electrolyte separator, leveraging partners’ knowledge in advanced materials. This new technology will be developed up to a TRL 6 (large prismatic cell ESP-Cell 30Ah) at the end of the project, producing these novel high voltage high capacity batteries close to practical applications. Further, the proposed solution will allow Europe to become more independent from raw material and the feasibility of a metal recovery process will be deeply investigated and recommendations for future application will be made. To achieve the ambitious targets, the CoFBAT project covers the entire value chain, bringing together industrial experts in material development and battery science together with engineering companies and institutes and battery producers and integrators.

To support the upcoming short-term needs of the battery industry, it is imperative to have new differentiating European battery technology for 4b generation batteries on the market from 2025. Halide solid state batteries for ELectric vEhicles aNd Aircrafts (HELENA) responds to the need of the development of a safe, novel high energy efficiency and power density solid state battery (4b generation batteries) cells, based on high capacity Ni-rich cathode (NMC), high-energy Li metal (LiM) anode and Li-ion superionic halide solid electrolyte for application in electric vehicles and, especially in aircrafts. HELENA will support Europe, in this sense, on its transition towards a climate-neutral continent since electric aviation is poised to take off within the next five to 10 years, with innovations already being pursued for electric vehicle batteries. Moreover, HELENA will avoid dependence on Asia for battery production. HELENA is built by a multidisciplinary and highly research experienced consortium that covers the whole battery value chain and proposes a disruptive halide-based solid-state cell technology with the overall aim to significantly increase the adoption of these batteries on aircrafts and EVs The technical challenges that are presented by current conventional battery technology and the consumer needs will be overcome - especially the reduction in costs of battery devices, enable scalable and safe cell manufacturing, increasing their capabilities for long distance traveling and fast charging, ensuring a high safety of the battery.

Wide global deployment of electric vehicles (EVs) is necessary to reduce transport related emissions, as transport is responsible for around a quarter of EU greenhouse gas (GHG) emissions, and more than two thirds of transport-related GHG emissions are from road transport. SUBLIME’s overall aim is to significantly increase EV adoption by taking on the technical challenges that are presented by the consumer needs - especially the reduction in costs of EVs, increasing their capabilities regarding long distance traveling and fast charging. SUBLIME concept entails development of a complete value chain, from requirements to testing, for new sulfide electrolyte based solid-state battery cells with high capacity and high voltage stability (scalable to mass production) to reach gravimetric energy density of >450 Wh/kg and volumetric Energy density of >1200 Wh/l. SUBLIME proposes the usage of high capacity and high voltage electrode materials. Li metal as anode (LiM), Ni rich NMC material e.g. or NMC90505 as cathode are foreseen to be used to achieve the targeted energy density. The battery will be inherently safe and will be able to operate at room temperature or lower; thus facilitating the start of the vehicle in broad operating conditions. Interfaces showing a fast Li-ion transport will be developed in the project and partners will focus on developing intimate and (electro)-chemically stable interfaces with strong mechanical properties. The interfaces will be specifically designed to increase stability of the component and the malleable nature of the sulfide enables good interfacial contact. SUBLIME will bring the sulfide electrolyte solid-state battery technology to TRL 6. The scale-up to pre-industrial volume will ensure that results are, indeed, scalable to large-volume commercial manufacturing. SUBLIME will deliver a roadmap to 2030, enabling eventual market entry by a very strong constellation of European partners, to bring about the transition towards electric
