A widely used sodium-ion battery developed by Chinese manufacturer Hina has achieved performance and manufacturing quality levels comparable to Tesla's lithium-ion batteries, according to research published in the Cell Press journal Cell Reports Physical Science.
The findings suggest sodium-ion technology could become a lower-cost alternative for future electric vehicles and large-scale energy storage systems. To reach that goal, however, the battery will need further improvements in low-temperature charging and energy density. Unlike lithium, sodium is abundant and readily available, making it an attractive material for reducing battery costs and supply chain concerns.
