The NaSiTec project focuses on the question of how the silicon content in hard carbon anodes influences the electrochemical performance and stability of sodium-based batteries and what potential such systems offer for sustainable energy storage.
The use of sodium-based battery systems with silicon-containing anodes is being investigated for its potential as a sustainable alternative to conventional lithium-ion batteries. The aim is the proof-of-concept of this technology with the aim of increasing the storage capacity by integrating silicon into a hard carbon electrode. To this end, electrode materials with varying silicon content are being developed and suitable electrolytes are being determined, electrochemically characterized and tested. The study addresses performance, manufacturing and stability issues and is intended to pave the way for industrial scaling.
