Spearheaded by experts at the University of Sydney, the project has designed a new sodium battery that not only has a significantly increased energy storage capacity compared to lithium batteries but also is much cheaper the produce. The battery innovation could play a pivotal role in transitioning to a decarbonised economy.<\/p>\n
The study, \u2018Atomically Dispersed Dual-Site Cathode with a Record High Sulphur Mass Loading for High-Performance Room-Temperature Sodium\u2013Sulphur Batteries<\/a>,\u2019 is published in Advanced Materials. <\/em><\/p>\n As the planet strives toward employing more environmentally friendly sources of energy to achieve climate neutrality, developing advanced energy storage technologies will be critical. A recent report from the Clean Energy Council<\/a> found that in Australia in 2021, 32.5% of the country\u2019s electricity came from clean energy sources. A further report on the Australian battery market<\/a> also suggested that household energy storage is increasing, with a record 33,000 batteries installed in 2021.<\/p>\n The novel battery was fabricated using sodium-sulphur \u2013 a molten salt that can be processed from seawater \u2013 meaning it costs much less than sourcing lithium. Although sodium-sulphur batteries have existed for more than 50 years, they have failed to become widely used due to their low energy capacity and short life cycles.<\/p>\n To overcome these limitations, the researchers employed a simple pyrolysis process and carbon-based electrodes to enhance the reactivity of sulphur and the reversibility of reactions between sulphur and sodium. This resulted in the sodium battery boasting a super-high capacity and ultra-long life at room temperature.<\/p>\n The sodium battery is a more energy-dense and less toxic alternative to lithium-ion batteries that are used in most electronic devices and are expensive to create and recycle. The battery is designed as a high-performing alternative for large renewable energy storage systems that reduces operational costs, including electricity grids.<\/p>\nEnergy storage needs are increasing exponentially<\/h3>\n
