To realize the universal goal of net-zero emissions by 2050, the world is keenly looking at advancements in battery technology. Lower costs, higher capacity, and optimal utilization of scarce natural resources are expected to play a major role in taking the mission forward.
Helping to realize the goal, a group of researchers at the University of Sydney has come up with a sodium-sulfur battery with a significantly higher capacity than lithium-ion cells. The battery also costs considerably less to manufacture.
Their findings were published in Advanced Materials.
After a series of downward revisions in the average price of lithium-ion batteries over the decade, rising raw material costs and inflation resulted in a seven percent increase in 2022 to reach $151/kWh.
“Our sodium battery has the potential to dramatically reduce costs while providing four times as much storage capacity. This is a significant breakthrough for renewable energy development which, although reduces costs in the long term, has had several financial barriers to entry,” said Dr. Zhao in a release.

The need for alternatives
The team led by Dr. Shenlong Zhao from the University’s School of Chemical and Biomolecular Engineering made use of a molten salt mixture of the constituent materials processed from seawater, which considerably reduces the cost.After a series of downward revisions in the average price of lithium-ion batteries over the decade, rising raw material costs and inflation resulted in a seven percent increase in 2022 to reach $151/kWh.
