Imagine replacing the leaky, flammable liquid inside a battery with a solid, plastic-like material that doesn't catch fire. This project creates a special 'single-ion' plastic layer that lets electricity flow efficiently while stopping dangerous spikes from growing. It's like swapping a risky liquid fuel tank for a stable, solid block that lasts longer and is safer to handle.
Current electric vehicle batteries rely on flammable liquid electrolytes that pose safety risks and limit energy density. Additionally, the manufacturing process often requires expensive and environmentally harmful organic solvents.
A prototype all-solid-state battery cell featuring a solvent-free extruded NCM 811 cathode and a single-ion conductive polymer electrolyte.
If you are an EV manufacturer dealing with battery fire risks and limited range — this project developed a solid-state battery using a lithium metal anode and NCM cathode that removes flammable liquids. This results in a safety hazard level 2 and higher energy density for longer driving ranges.
If you are a cell producer dealing with expensive and toxic organic solvents in production — this project developed a solvent-free extrusion process. This allows for a more sustainable, cost-effective way to manufacture high-voltage batteries.
If you are a storage provider dealing with the instability of high-energy lithium cells — this project developed amorphous cross-linked PEO electrolytes. This ensures dendrite-free cycling and improved reliability for large-scale energy systems.
The project utilizes solvent-free extrusion processes and cheap solid polymer electrolytes to reduce manufacturing costs and the overall ecological footprint.
Yes, the materials selection is specifically designed to use manufacturing technology available at BlueSolutions, which is described as readily scalable.
Based on available project data, specific licensing terms are not listed, but the project is coordinated by BlueSolutions with a consortium of 16 partners.
The project aims to achieve a safety hazard level 2 by completely removing liquid components from the battery cell.
The project period runs from 2022-07-01 to 2026-06-30, with initial prototype electrodes already extruded and assessed within the first 18 months.
The consortium is heavily industry-weighted with a 56% industry ratio (9 industrial partners, including 4 SMEs), suggesting a strong push toward commercialization. Led by BlueSolutions, a French company with existing scalable extrusion technology, the group spans 6 countries and balances academic research (5 universities, 2 research institutes) with practical manufacturing expertise.
