If you are an EV manufacturer dealing with short driving ranges and battery safety concerns — this project developed a Gen 4b battery cell that reaches energy densities >380 Wh/kg. This allows for longer range vehicles with a safe-by-design architecture.
Sustainable High-Energy Solid-State Lithium Metal Batteries for EVs and Energy Storage
Imagine replacing the flammable liquid inside a battery with a solid, safe material that acts like a sturdy wall. This allows the battery to hold much more energy in a smaller space without the risk of catching fire. It's like upgrading from a leaky water balloon to a solid power brick that is easier to recycle.
What needed solving
Current Li-ion batteries use flammable liquid electrolytes and critical raw materials, limiting their safety and sustainability. There is a market need for high-energy-density batteries that are safe, recyclable, and affordable for EVs.
What was built
A TRL5 battery cell featuring a hybrid organic-inorganic electrolyte, a thin Li metal anode, and a cathode free of critical materials, produced via solvent-free extrusion.
Who needs this
Who can put this to work
If you are a stationary storage provider dealing with high material costs and environmental regulations — this project developed a cell using sustainable, recyclable materials and a solvent-free extrusion process. This reduces the environmental footprint of large-scale energy grids.
If you are a cell producer dealing with expensive liquid electrolyte handling and critical raw material shortages — this project developed a hybrid electrolyte and a cathode without critical materials. This lowers production costs and secures the supply chain.
Quick answers
How does this impact the cost of battery production?
The project focuses on a low-cost, solvent-free extrusion process and the use of sustainable materials to reduce manufacturing expenses. Based on available project data, the goal is to create a cost-effective battery cell.
At what industrial scale is the technology currently?
The project aims to reach a TRL5 milestone by 2026. This means moving from lab-scale development of organic and inorganic phases to a validated cell device.
What is the IP or licensing status of the hybrid electrolyte?
Based on available project data, specific licensing terms are not mentioned, but the project involves 24 partners including 9 industrial entities developing the value chain.
How does this align with EU environmental regulations?
The cell design is guided by the latest EU regulations and includes an innovative recycling cycle from the material level up to the full cell.
What is the timeline for the final results?
The project is scheduled to run from July 2022 to June 2026, with the target of meeting EV and stationary needs by 2026.
Who built it
The consortium is well-balanced for commercialization, featuring 24 partners across 8 countries. With 9 industrial partners (including 3 SMEs), the industry ratio is 38%, ensuring that the research is grounded in market needs. The mix of 6 universities and 9 research organizations provides the necessary R&D depth to move the technology toward the TRL5 target.
