Ceit-IK4 is participating in a project that will increase battery life in electric vehicles.

The European project ALISE (Advanced Lithium Sulphur battery for xEV), which is being carried out by a consortium that includes Ceit-IK4, aims to increase the life of batteries in electric vehicles as well as scale up their commercialisation by installing them in PHEVs (plug-in hybrid electric vehicles) and FEVs (fully electric vehicles). The limited range of these vehicles is the main obstacle to their development, and Alise is working on a new battery that will increase vehicle range well beyond current limits.

The project will develop a lithium-sulphur (LiS) battery that will have a capacity of up to 500Wh/kg (Watt hour/kilogram), which contrasts with current ion-lithium batteries that do not exceed 210Wh/kg. This advance will double the number of kilometres that these vehicles can currently travel on a single charge.

At the same time, Alise includes a plan for commercialising these LiS batteries at a competitive price, making it possible for them to be introduced into the market.

Alise is financed by the European Union under the Horizon 2020 programme and has a budget of 7 million euros. A pan-European consortium made up of 15 partners from various sectors is collaborating on the research driving Alise. The project was recently presented at the 4th Workshop on Lithium-Sulphur Batteries, which was organised by Fraunhofer IWS and held in Dresden (Germany).

This project is the only one in Europe that aims to integrate lithium-sulphur batteries in PHEVs and to validate them on circuit. The final goal of the Alise researchers is to deliver a 17kWh battery that will be installed in a vehicle by manufacturer Seat for testing.
