The goal is to fulfil Europe's need for a safe, loftier-energy, sustainable and marketable bombardment for green mobility that could be manufactured in Europe on a massive scale. To practice and then, the new ASTRABAT cells will enable:
ASTRABAT is part of a broader bulldoze by the European Union to make electric mobility become the side by side ship mode and contribute to the European union overall goal to reduce greenhouse gas (GHG) emissions by 80-95% by 2050 (currently, the ship sector is responsible for effectually one quarter of Europe's GHG emissions). It is expected that east-mobility will represent seventy% of the total rechargeable Li-ion battery cell market'southward value in 2022 and that seventy% of the Eu electricity should exist produced by renewable energies. Hence, the electric bombardment storage is vital in this transition to clean mobility and make clean energy systems.
Our innovation
This video presents how ASTRABAT is innovating in solid-state lithium-ion batteries using the latest generation of materials.
Technology
Li-ion batteries for electric vehicles suffer from several problems:
- Insufficient energy density to comply with expected electric vehicle autonomy of 500 km;
- Hazardous in prophylactic due to strong battery thermal run away;
- Unsatisfactory power density to come across fast accuse requirement;
- Lack of battery Giga-factories in Europe.
To overcome these problems, ASTRABAT will:
- Develop materials for a solid hybrid electrolyte and electrodes enabling high energy, high voltage and reliable all-solid-state Li-ion cells;
- Adjust the evolution of new all-solid-country batteries to a conventional process adopted for manufacturing electrodes in Li-ion cells;
- Design an all-solid-state-battery architecture for the next generation of 2030 Li-ion batteries;
- Define an efficient cell architecture to comply with improved safety demands;
- Generate a new value chain of all-solid-country batteries, including eco-design, end of life and recycling.
How volition ASTRABAT become across the state of art of solid-state electrolytes?
ASTRABAT hybrid electrolyte will be based on polymers (ORMOCER® and fluorocarbon polymers) and an inorganic filler and membrane (LLZO). These materials will tackle the generation 4a of cells using loftier voltage cathode materials, based on Nickel Manganese Cobalt Oxide (NMC) such as NMC622 and NMC811, and Si-based anode. All developed cells will exist assessed following standard safety protocols and safety certifications volition be performed.
For the ceramic LLZO cloth, an ionic electrical conductivity of 0.4 mS/cm in the range temperature of 10°C – l°C will be achieved via Al-doping or Ta-doping. This should enable a decrease of the cell operating temperature and render a more efficient electric vehicle. Moreover, an optimised ionic send volition be achieved past tailoring electrode-electrolyte percolation networks to reduce the ionic pathway length. This will be washed by optimising the electrode conception and by developing new processes to generate organised electrolyte structures.
The improved impedance of the electrode-electrolyte interface will exist accomplished by developing an inorganic coating on NMC material, organic coating on LLZO and carbon coating on silicon. Dissimilar particle sizes of active electrode materials will be synthesised and volition contribute to a meliorate harmonisation of the material.
Short cycle life will exist avoided thanks to material coatings on NMC that will reduce the chapters fading generated by interfacial reactivity of electrode material with the electrolyte. At the anode side, the Si particle size and carbon coating are also a source of improvement of electrode stability and reduction of irreversibility by solid electrolyte interface germination.

Young man projects
International agreements towards less air pollution and CO2 production, such as the Paris Agreement (COP21), and the European Wedlock 2020 and 2050 targets, are pushing towards a rapid implementation of electrification of transport. Electrical batteries are currently seen every bit cardinal technological enablers to allow a rapid growth of the sales and deployment of battery electric vehicles. A battery technology with college driving range, lower charging fourth dimension, increased condom, increased sustainability and depression-cost manufacturing will accelerate the market introduction of electric vehicles in the world. This understanding is framed by initiatives such as Batteries Europe, the European Bombardment Brotherhood, Battery 2030+, and, on a global level, the World Economic Forum's Global Battery Alliance.
Considering the global contest, the European Union is focusing substantial research efforts to create an improved European battery engineering science. Under the EU Research and Innovation program Horizon 2020, numerous calls for proposals focus on unlike aspects of battery inquiry. One of these is the LC-BAT-i-2019 phone call, which addresses the global involvement on solid state batteries every bit an alternative to ensure higher performance, simply also inherently condom batteries.
In addition to ASTRABAT, three projects have been funded by the European union to work under the LC-BAT-1-2019 call. Read their description below and follow our updates on social media with the hashtag #LCBAT12019. Moreover, ASTRABAT is besides collaborating with COBRA, funded under the LC-BAT-5-2019 telephone call.
SUBLIME
SUBLIME proposes the usage of high capacity and high voltage electrode materials. The bombardment volition be inherently safe and will be able to operate at room temperature or lower; thus, facilitating the first of the vehicle in broad operating weather.
Interfaces showing a fast Li-ion transport will be developed in the project and partners volition focus on developing intimate and (electro)-chemically stable interfaces with strong mechanical properties. The interfaces will be specifically designed to increment stability of the component and the malleable nature of the sulfide enables good interfacial contact.
SUBLIME will bring the sulfide electrolyte solid-country battery applied science to TRL 6. The calibration-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 potent constellation of European partners.
SOLiDIFY
The SOLiDIFY project proposes a unique manufacturing process and solid-electrolyte fabric to fabricate Lithium-metal solid-state batteries – known as Gen. 4b on the EU battery roadmap.
The concept is based on a solid nanocomposite electrolyte or nano-SCE. It is fabricated by a sol-gel reaction which is used advantageously for a liquid-tosolid approach in the fabrication of the blended cathode and the solid-electrolyte separator. The general strategy to achieve the target energy density of 1200Wh/L (400Wh/kg) in 20 minutes charging time is: (1) enabling the integration of high-free energy NMC active materials and (2) evolution of new electrode architectures for high mass loading and enabled by the liquid-to-solid approach. An added imposed challenge is a water-based prison cell assembly process. To this end, suitable protection of the loftier-free energy NMC pulverization with ALD thin-motion-picture show coatings is pursued. Finally, thin lithium foils with protective artificial interphase coatings will be developed for lamination on the nano-SCE separator.
The main goal of SOLiDIFY is to bring the liquid-candy solid-state prison cell fabrication concept from demonstration in the lab (TRL3) to demonstration of prototypes in pilot line (TRL6), with upscaling of the concept both towards (i) the development of manufacturable materials and processes and (2) the discovery of full cell assembly schemes with ultimate demonstration of 1Ah pouch cells. The fabric enquiry will focus on (i) solutions enabling the upscaling process and manufacturability and (ii) further improvement of jail cell integration steps to heighten functioning.
Manufacturable parameters such price, environmental touch on and recycling will also be handled. The larger telescopic of the SOLiDIFY projection entails the development of a novel and potentially European-atomic number 82 solid-state battery applied science with fully covered Eu value chain.
