The project handbook "New efficient lithium batteries for electric vehicles" summarises the main achievements of the ASTRABAT project. During its 4 years of activities (January 2020 - December 2023), ASTRABAT investigated and developed a new all-solid-state Li-ion cell architecture suitable for the use of high-energy electrode materials. The ASTRABAT hybrid electrolyte is based on polymers (ORMOCER® and fluorocarbon polymers) and an inorganic filler and membrane (LLZO). These materials tackle the generation 4a of cells using high voltage cathode materials, based on Nickel Manganese Cobalt Oxide (NMC) such as NMC622 and NMC811, and Si-based anode. The project aimed to assess compatible processes for mass production and to generate a new value chain of all-solid-state batteries, including eco-design, end-of-life and recycling.

Eco-design and LCA studies have been carried out to address the need to enhance the sustainability of lithium-ion batteries by reducing its carbon footprint and other environmental impacts. The studies also address the use of critical raw material for batteries.
Info pack 3: Fluorine-free ionic liquid plasticizers for all-solid-state Li-ion batteries
PDF — 1.28 MB — 05 Jun 2023
The ASTRABAT project’s aim is to develop all-solid-state Li-ion batteries. The most critical new component here is hybrid solid electrolyte, which has to contain plasticizer – an ionic liquid. Within the project, the new set of ionic liquids were synthesised which improve electrolytes far above the state-of-the-art and are fluorine-free.
