Development of innovative, low-cost NaFePO4-type Sodium-Ion-Batteries based on recovery of LiFePO4-material from spent Lithium-Ion-Batteries - LIB2SIB

Project summary

The European Green Deal aims to transform the EU into a resource-efficient and competitive economy, achieving no net greenhouse gas emissions by 2050 and economic growth decoupled from resource consumption. Lithium-ion batteries (LIBs) are set to become one of the world´s most important green energy storage technology, widely used in mobile and stationary applications. The ever-growing market of LIBs to meet the demand for such applications raises concerns regarding the depletion of limited Li resources. Among all proposed alternative concepts, sodium-ion batteries (SIBs) have the greatest potential as the underlying chemistry of SIBs resembles that of LIBs while benefiting from abundant Na resources (ca. 440 times more abundant than Li). The aim of this project is to utilize spent LIBs to provide a breakthrough in the development of cheap, safe, stable and sustainable new generation of SIBs, thus reducing the price and enabling new paths to circular economy and life-cycle-assessment.
