Climate change has long been pushing the globe towards carbon neutrality, which urges the transition from conventional energy systems to renewable ones like chemical batteries and battery-powered machines. The chemical lithium-ion batteries thereby have set their dominance for applications in consumer electronics, automobiles, and even aviation since their commercialization by Sony Corporation in 1991. However, the energy shift is facing the lithium supply crunch with rising large-scale demand. Referring to the periodic table of elements, sodium and lithium are the closest metals in the same group with very similar chemical properties, and there is over one thousand times sodium than lithium in the Earth’s crust. Sodium-ion batteries thereafter have been a revival to be the optimal alternative with a consistent working principle.
