One company has found a solution that improves lithium-sulfur batteries’ life cycle.

Li-S batteries offer higher energy density for longer EV ranges, use abundant and eco-friendly sulfur, and could be cheaper and safer than lithium-ion. 

However Li-S batteries have historically had a shorter cycle life than Li-ion (often only a few hundred cycles compared to thousands for Li-ion) posing a significant challenge for commercialization.

Li-S Energy (Australia) has tackled this by developing cathode materials that trap polysulfides and prevent their movement. 

It uses unique nanomaterials, Boron Nitride Nanotubes (BNNTs), and a new nano-composite called Li‑nanomesh™ to enhance a battery’s strength, life cycle, and performance.

Li‑S Energy was born through the collaboration of two teams of specialist nanomaterials scientists, Deakin University Institute of Frontier Materials and Brisbane company BNNT Technology Limited. 

The startup is now a public company with nearly $100 million in market capital.
