Welcome to the SiGNE Project

Composite Silicon Nanowire on Graphite Anodes with Ni-Rich Cathodes and Safe Ether based Electrolytes for High-Capacity Li-ion Batteries

About the SiGNE Project

SiGNE is an €8 million Horizon Europe funded project led by Professor Kevin M Ryan with collaborators Professor Hugh Geaney and Professor Tadhg Kennedy at the University of Limerick, Ireland with 16 Partners in total from across Europe.

SiGNE Project Objectives

The objectives of SiGNE are to deliver an advanced lithium-ion battery (LIB) for Electric Vehicles that will deliver higher energy (50% increase in both specific and volumetric) and power density (300% increase) in an equivalent pack size than that achievable using commercial cell chemistries.

This will be achieved by materials developments at component level of the battery of anode, cathode, separator and electrolyte that are optimised for rapid transition to prototype development and manufacturing with minimal environmental footprint.

The advances obtainable with this technology will translate to a 50% range enhancement for EVs with a similar pack size. In real terms, this would push the maximum range from 540 kms (higher end of what is currently available) to 810 Kms which is a similar range to an internal combustion engine with a full tank.

The technology will be cost competitive and allow for fast charging and extremely long and stable cycle life that will facilitate significant second use of the batteries beyond the lifetime of the car.
