The Challenge
Sodium-ion batteries are a promising alternative to lithium-based systems, but metallic sodium anodes suffer from rapid degradation, dendrite formation, and poor cycle stability.
These effects severely limit battery lifetime and performance.
The Patented Solution
A sodium-ion secondary battery with a chemically stabilised sodium anode, achieved by:
controlled oxidative hydrolysis in air,
formation of a nanocrystalline porous anode surface, and
an ionically bonded passivation layer containing hydroxyl groups.
This approach effectively suppresses dendrite growth and stabilises the electrochemical behaviour of metallic sodium.
