Sodium-Ion and sodium Metal Batteries for efficient and sustainable next-generation energy storage


Institute of Inorganic Chemistry, Slovak Academy of Sciences is participating in the SIMBA project “Sodium-Ion and sodium Metal BAtteries for efficient and sustainable next-generation energy storage” under the grant agreement 963542 has started on the 1st of January 2021. The Kick-off meeting took place online and headstarted a highly ambitious project to develop sustainable and safe batteries to store renewable energy.

The SIMBA project has the concrete goal of delivering a safe and low-cost all-solid-state-sodium battery technology for stationary application. Reducing the use of critical materials is the core of SIMBA, which will employ sustainable battery materials, reducing supply risks and restrictions and environmental impact, which are instead currently affecting other technologies, i.e. Lithium-ion batteries. The unprecedented concept of SIMBA is based on the integration of a sodium metal anode in a sodium free assembly architecture including a highly porous support on the anode side, a single-ion conductive composite/hybrid polymer electrolyte and an innovative cathode material.

SIMBA gathers a consortium of 16 partners from 6 EU and associated countries having received a funding from the European Commission of 8M €.
