(Source: ANSTO - Australian Nuclear Science and Technology Organisation) Sodium-ion batteries are a type of reusable battery that uses sodium ions as charge carriers. The sodium salts used to prepare these battery materials are cheaply abundant, much more so than those of lithium salts, making them a cost-effective alternative . As of 2014 Aquion Energy offered a commercially available sodium-ion battery with cost/kWh capacity similar to a lead acid battery for use as a backup power source for electricity micro-grids. Another company, Faradion, offered for license a range of low-cost sodium-ion materials, which are a drop-in replacement for established lithium-ion technology. Unlike...
