Summary

The Lithium-Sulfur Batteries for Large-Scale Energy Storage project aims to develop advanced batteries for renewable energy storage with high energy density, extended service life and operation safety.

Need

The lack of cost effective energy storage technologies has hindered progress for intermittent solar energy and in renewable energy industries. Lithium-sulfur battery technology has the potential for high energy density and low cost large-scale energy storage and conversion.

The technical challenges facing the development of lithium-sulfur batteries are formidable, including:

  • insulating nature of sulfur leads to poor power density
  • limited cycle life
  • high reactivity of the lithium metal anode presents as a safety issue.

The Lithium-Sulfur Batteries for Large-Scale Energy Storage project will help to overcome these hurdles.

Project innovation

This project aims to develop advanced lithium-sulfur batteries for renewable energy storage with high energy density, extended service life and operation safety.

It will advance a number of innovative technologies required for the development of high performance batteries, including:

  • design and synthesis of carbon-based materials with new architecture for sulfur cathodes
  • confinement of dissolvable polysulfide to extend life of the battery
  • solid-state electrolyte to improve the safety of battery operation.

These advancements will be incorporated into the fabrication and demonstration of prototype lithium-sulfur batteries.

Benefit

This project is expected to herald breakthroughs in the development of practical lithium-sulfur batteries. It is the most promising system for large-scale energy storage, in particular renewable energy.

When completed, the project will significantly advance energy storage technology towards commercialisation. This will allow renewable energy, particularly wind and solar, to better compete with fossil fuels by providing more reliable power.
