High-Capacity Battery Technology for Longer Range and Faster Charging Electric Vehicles

transportTestedTRL 5

Imagine a battery that acts like a larger fuel tank but fits in the same space, allowing cars to drive much further. It uses tiny silicon wires to pack more energy and a special liquid to keep everything stable and safe. It's designed to be recycled, so the materials can be used again to build new batteries.

The business problem

What needed solving

Current EV batteries suffer from limited energy density and slow charging, while the supply chain lacks sustainable, circular recovery methods for critical materials.

The solution

What was built

A high-capacity battery system featuring Si-nanowire/graphite anodes, Ni-rich NCM cathodes, and fiber-based separators, validated in 21700-type cylindrical and pouch cells.

Who can put this to work

Automotive
enterprise
Target: Electric Vehicle (EV) Manufacturer

If you are an EV manufacturer dealing with range anxiety and slow charging times — this project developed a battery cell with >550 Wh/kg energy density that enables faster charging and higher capacity.

Battery Manufacturing
enterprise
Target: Gigafactory Operator

If you are a battery producer dealing with the difficulty of scaling silicon anodes — this project developed a process to scale Si-nanowire/graphite composites to 100 g reactor production with stable performance.

Waste Management
mid-size
Target: Battery Recycling Firm

If you are a recycling company dealing with low recovery rates of battery materials — this project developed a circular economy approach for the recovery of anode, cathode, and electrolyte components.

Frequently asked

Quick answers

How cost-competitive is this technology?

The project aims to demonstrate high cost-competitiveness and cost-effectiveness through circular economy considerations and 2nd life battery applications.

Can this be produced at an industrial scale?

Yes, the project has already scaled Si-nanowire/graphite anodes to 100 g reactor production and upscaled fiber-based separators to industrial paper-machine production.

What are the IP and licensing options?

Based on available project data, specific licensing terms are not listed, but the project involves 9 industrial partners, suggesting a strong focus on industrial uptake.

How does it integrate into current EV designs?

The technology is being optimized for manufacture as a 21700-type cylindrical cell, which is a standard format for many EV battery packs.

What is the timeline for deployment?

The project runs from September 2022 to February 2027, with current reports showing successful pouch-cell testing and component upscaling.

Consortium

Who built it

The consortium is heavily industry-weighted with 9 industrial partners (53% of the total), including 2 SMEs. This strong industrial presence, spanning 9 countries, indicates that the research is tightly coupled with commercial manufacturing requirements rather than being purely academic.
