Sulfur-Aluminium Battery with Advanced Polymeric Gel Electrolytes (SALBAGE)
In SALBAGE Project, a new secondary Aluminium Sulfur Battery will be developed. The focus will be put in the synthesis of solid-like electrolytes based on polymerizable ionic liquids and Deep Eutectic Solvents in order to obtain polymer-gel electrolytes with an overall ionic conductivity in the range of 1-10 mS/cm at room temperature. At the same time, the aluminium negative electrode will be combined with a sulfur positive electrode including the unprecedented use of redox mediators, to facilitate sulfur reaction kinetics and boost performance.
To achieve this objective a strong consortium has been gathered, with reputed experts in all the relevant fields, such as development of ILs and DES (University of Leicester, and Scionix Ltd.), polymers (ICTP- CSIC), synthesis and characterization of materials for aluminium anode (TU Graz) and sulfur-cathode (Univ. of Southampton) and computational modelling (TU Denmark). This consortium is coordinated by ICTP-CSIC and also includes a European SME’s, Albufera Energy Storage, expert in the development and testing of batteries.
The new battery is expected to have a high energy density (1000Wh/kg) and low price compared with the actual Li-ion technology (-60%). Moreover, we will take advantage of the special features of the resulting battery (flexibility, adaptability, shapeability) to design a new device with the focus put on strategic applications such as transport, aircraft industry or ITs, for which the SALBAGE battery will be specially designed and tested in relevant conditions.
