EU launches $7.6M ALISE to develop Li-sulfur batteries for plug-ins; targeting stable 500 Wh/kg cell by 2019
Under the European Union’s Horizon 2020 research and innovation program, the EU has launched ALISE (Advanced Lithium Sulfur battery for xEV), a pan-European collaboration focused on the development and commercial scale-up of new materials and on the understanding of the electrochemical processes involved in lithium-sulfur technology. The €6,899,233 (US$7.6 million) project is focused on achieving a stable 500 Wh/kg Li-S cell by 2019.
ALISE includes the development of the key components of the cell—anode, cathode and electrolyte—and will culminate in an ultra-lightweight 17 kWh battery for a SEAT (a member of the Volkswagen Group) vehicle for testing on-track and public roads. LEITAT is the lead organization involved and will co-ordinate and manage the entire project, which also incorporates dedicated durability, testing and lifecycle analysis (LCA) activities to deliver safety, adequate cyclability and competitive cost.
Initial materials research will be scaled up during the project so that pilot scale quantities of the new materials will be introduced into the novel cell designs, delivering advancements over the current state-of-the-art. Activities will be focused on the elaboration of new materials and processes at TRL4.
The largest single funding award to the 15 participating partners goes to UK-based Li-S battery company OXIS Energy (€953,025 / US$1,050,000), which has already achieved 325 Wh/kg with its Li-sulfur technology.
OXIS will lead the work to develop the anode, the critical area needed to achieve high cycle life. Aided by LEITAT, The Technical University of Dresden, Polito and C-Tech Innovation, OXIS will develop both anode coatings and alternatives to the pure lithium used today.
OXIS will also work to develop the cathode and electrolyte. The company will partner Fraunhofer IWS and Solvionic.
OXIS will then use its experience of Lithium Sulfur manufacturing to scale-up the assembly of this new generation of cells from lab scale to pilot production scale. SEAT, aided by OXIS, VARTA, Ficossa, CEIT, Idneo and RDVS will integrate these cells into its vehicle.
OXIS has already built several Lithium Sulfur batteries including for e-bikes, energy storage and an EV battery, integrated into the world’s first Lithium Sulfur powered EV.
