Sodium instead of lithium for cheaper batteries

One of the obstacles to the widespread spread of electric vehicles is the high cost of lithium-ion batteries, but researchers argue that lithium can be replaced with a similar cheaper alkali metal such as the sodium easy-to-find by being present in salt. Trials with sodium-ion batteries have performed well and do not require use in cells of high environmental impact materials such as for example the cobalt, although it will take longer before being able to switch to large-scale mass production; then problems remain to be overcome such as higher sodium weight, lower yield and slightly lower voltage of batteries. There is theoretical talk of sodium multilayers between two layers of graphene and other ploys to improve a technology much more environmentally friendly than that based on lithium.
