As society continues to shift toward becoming carbon neutral, the demand for electric vehicles (EVs) and renewable technologies exponentially increases. Mirroring this rising demand is the demand for high energy density rechargeable batteries, such as lithium-ion batteries, the battery technology currently used in EVs. However, to ensure that EV uptake can increase, it must be guaranteed that the best possible battery technology is used.<\/p>\n
Now, sodium batteries, which have a resource advantage over the current lithium-ion batteries, are attracting significant attention as cheap, new high-performance materials continue to be developed.<\/p>\n
To improve these batteries to ensure they are advantageous over lithium-ion batteries, a research group led by Associate Professor Atsushi Sakuda, President Masahiro Tatsumisago, and Professor Akitoshi Hayashi, from Osaka Metropolitan University\u2019s Graduate School of Engineering, has developed a new positive electrode, made of Na2<\/sub>FeS2<\/sub>, for all-solid-state sodium batteries. These batteries have a high energy storage capacity and high reversibility.<\/p>\n The research paper, titled \u2018Iron sulphide Na2<\/sub>FeS2<\/sub> as Positive Electrode Material with High Capacity and Reversibility Derived from Anion\u2013Cation Redox in All-Solid-State Sodium Batteries,\u2019<\/a> was published in the journal Small. <\/em><\/p>\n Sodium batteries are comprised of inexpensive elements that are readily available, a significant advantage over lithium-ion batteries. Mining for lithium in certain areas is often considered unethical, and requires a lot of natural resources, for example, water, to assist with its extraction. Using sodium instead could provide a more sustainable form of green energy, removing any challenges regarding the world\u2019s transition to clean energy.<\/p>\n However, compared to lithium-ion batteries, sodium batteries have a limited performance<\/a> which has prevented the large-scale rollout of this battery technology. The researchers aim to change this.<\/p>\nAdvantages of sodium batteries<\/h3>\n
