Lithium-sodium ion batteries have now become a part of our everyday life. However, these power sources have a potential danger of explosion under specific circumstances which makes them a little non-suitable for grid-scale energy storage. Sodium-ion batteries happen to be one of the most safe and economic option, however, the present version are not that long lasting which makes them a less practical option. Now, a team of scientists came up with an anode material that allow the sodium-ion batteries to perform better across hundreds of charging-recharging cycles.
For several years, scientists have been working to find a safer and enduring version of sodium-ion batteries for large scale storage that they could replace these with lithium ion. But till date, sodium-ion batteries that can last longer and perform better. Lithium and sodium have almost similar characteristics in a lot of ways, however, sodium ions are much larger as compared to lithium. This difference in ion size leads to fast deterioration of a specific battery component. Chenghao Yang, Meilin Liu, and their teammates needed to discover an anode material that can grant a longer life to sodium ion batteries.
The team adopted a very basic approach to come up with high-performance anode material binding sulfur-doped graphene sheet with antimony-based mineral inducing the anode inside a sodium-ion battery. This allowed them the sodium-ion battery to perform by 83 percent for more than 900 cycles. The research team claims that it is the best performance reported for a sodium-ion battery with a complete antimony-based anode material. In order to commercialize this technology, they may need to scale up the fabrication of this battery as they maintain its high performance
