Researchers at the University of Sydney have announced a new low-cost battery built with four times the capacity of lithium-ion. Researchers hope that a new low-cost battery that is much cheaper to produce will significantly reduce the cost of transitioning to a low-carbon economy. Led by Dr. Shenlong Zhao from the University’s School of Chemical and Biomolecular Engineering, the battery was made from sodium-sulfur – a type of molten salt that can be processed from seawater – costing much less to produce than lithium-ion.
The team’s paper titled “Atomically Dispersed Dual?Site Cathode with a Record High Sulfur Mass Loading for High?Performance Room?Temperature Sodium–Sulfur Batteries” was published in the journal Advanced Materials.

Although sodium-sulfur (Na-S) batteries have been around for over half a century, they have been an inferior alternative and their widespread use has been limited by low energy capacity and short life cycles.
Using a simple pyrolysis process and carbon-based electrodes to improve sulfur reactivity and the reversibility of sulfur-sodium reactions, the researchers’ battery has shaken off its once-slow reputation, exhibiting super-high capacity and longer life. ultra long life at room temperature.
The researchers say the Na-S battery is also a more energy-dense and less toxic alternative to lithium-ion batteries, which, although used extensively in electronic devices and for energy storage, are expensive to manufacture and recycle.
Dr. Zhao’s Na-S battery was specifically designed to provide a high performance solution for large renewable energy storage systems, such as power grids, while significantly reducing operating costs.
According to the Clean Energy Council, in 2021, 32.5% of Australia’s electricity came from clean energy sources and the industry is accelerating. Home energy storage is also growing. According to a recent report, a record 33,000 batteries were installed in 2021.
Lead researcher Dr Zhao said, “Our sodium battery has the potential to significantly reduce costs while providing four times the storage capacity. This is an important breakthrough for the development of renewable energy which, although it reduces long-term costs, has come up against several financial barriers to entry. When the sun isn’t shining and the breeze isn’t blowing, we need high-quality storage solutions that don’t cost the earth and are easily accessible locally or regionally. »
“We hope that by providing technology that reduces costs, we can reach a clean energy horizon more quickly. It probably goes without saying, but the faster we can decarbonise, the more likely we are to limit warming. ” He added. “Storage solutions made from abundant resources like sodium – which can be processed from seawater – also have the potential to provide greater energy security more broadly and enable more countries to join the transition to decarbonization.”
Lab-scale batteries (button cells) have been successfully manufactured and tested at the University of Sydney’s chemical engineering facilities. The researchers now plan to improve and commercialize the newly fabricated Ah-level pocket cells.
It is hoped that sodium-sulfur chemistry for batteries will continue to evolve. The work of this team is a major improvement and signals that there is a lot of room for innovation to improve this chemistry. Kudos are in order for the knowledge being put to good use for the benefit of the entire battery complex, from the raw material producers to the end user. A fourfold increase would be a huge boon to consumer products and depressurize demand for lithium in the overall market.
Too bad the motivation expressed is based on grid storage. But the team is working in a market run by politicians and bureaucrats instead of engineers, which is pushing for “decarbonization”, which is kind of scary because carbon dioxide is the main source of food for plants on earth. – which feeds, well, Everything and Everyone.
