Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. As reported in a paper in Nature Energy , the Stanford team achieved four-sodium storage in a Na 2 C 6 O 6 electrode with a reversible capacity of 484 mAh g −1 , an energy density of 726 Wh kg −1 cathode , an energy efficiency above 87% and a good cycle retention.

Researchers propose new VO2 cathode material for aluminum-ion rechargeable battery

Green Car Congress

Sodium-ion and magnesium-ion batteries, as new energy storage systems in portable devices, have attracted much attention of the investigators. Some multivalent metal elements, such as aluminium and titanium, are abundant metallic elements in the earth’s crust with low price. Schematic representation of the super-valent battery during charge/discharge process. Wang et al. Click to enlarge.
