Several batteries have been designed, however, for the first time, one of these batteries has been designed which is capable of storing l at the same energy as a lithium battery but at a lower cost .

The battery, in particular, costs about 80 percent of a lithium-ion battery with the same storage capacity. As explains Bao :
Nothing can outperform lithium. But lithium is so rare and expensive that we need to develop high-performance but low-cost batteries based on abundant elements such as sodium.
The sodium salt forms the cathode, which is the pole of the battery that stores the electrons. The internal chemistry of the battery moves these electrons towards the anode, which in this case is made of phosphorus. Stanford researchers believe that their study shows that sodium batteries can be cost-effective alternatives to lithium batteries .
