Developing a high energy and safe lithium-sulphur battery for automotive integration


Optimat is delighted to announce that it is a partner in a new collaborative Research & Development project, which has been granted 7.9M€ by the European Union’s Horizon 2020 program to develop a high energy and safe lithium-sulphur battery (Li-S) for electrified vehicles (EVs).  The project is known as LISA, which stands for “LIthium sulphur for SAfe road electrification” and will officially start on 1st January 2019, running for 43 months.  A total of 13 research, academic and industrial organisations from across Europe are involved including Leitat (ES), the project co-ordinator, OXIS Energy Ltd. (UK), Cranfield University (UK), Varta MicroBattery GMBH (DE), Centro De Investigacion Cooperativade Energias Alternativas Fundacion CIC Energigune Fundazioa (ES), Arkema (FR), Fraunhofer-Gesellschaft IWS (DE), Pulsedeon Oy (FI), ACCUREC Recycling GMBH (DE), Optimat Ltd. (UK), Technische Universität Dresden (DE), VDL Enabling Transport Solutions BV (NL) and Renault SAS (FR).

The goal of LISA is to develop a high energy and safe lithium-sulphur (Li-S) battery cell with hybrid, solid state, non-flammable electrolytes for automotive integration. The aim is to validate the cell at 20Ah according to EUCAR industrial standards. In addition, LISA will solve specific lithium sulphur batteries bottlenecks such as metallic lithium protection, power rate, and volumetric energy density. A target has also been set for production cost, as it is the main selection criteria for EVs batteries.

Li-S technology has three main advantages over the current Li-ion technologies used in electric vehicles: A Li-S battery can be half the weight, which has significant benefits for vehicle weight reduction; it has a theoretical energy density of 2,600 Wh/kg which is much higher than the 150-180 Wh/kg current density of Li-ion; and it is a low environmental impact technology, which is fully compatible with mass production by green and low-energy processes  delivering a technology free of critical raw materials and toxic components as Li-S battery chemistry does not require the use of natural graphite, cobalt or nickel.  Thus, improving Li-S technology could be a key factor to stimulate the wide-scale adoption of electrified vehicles.

Optimat’s will lead on the dissemination of project outputs, including exploitation and business planning activities.
