SODIUM-ION BATTERY

Solution to dissolution

Nature Energy volume 7, pages 682–683 (2022)Cite this article

Subjects

One of the key targets for further development of sodium-ion batteries is to improve their cycle life. Now, an electrolyte formulation is proposed to tackle the dissolution of both the solid-electrolyte interphases and the transition metals in cathodes, leading to enhanced cyclability.

Until recently, sodium-ion batteries (NIBs) were often seen as an inherently inferior storage technology in their performance to commercialised lithium-ion batteries (LIBs). However, great progress has now been made in the development of NIBs and their energy and power densities have started to rival some LIBs1,2,3. The cycle life of NIBs, on the other hand, remains an urgent research topic.
