Following another funding round, British battery start up Faradion says it has almost £2million to invest in developing low cost, high energy density sodium-ion batteries. The company says the technology has the potential to revolutionise the supply of electric batteries for stationary storage, automotive applications and e-bikes.
"With this latest demonstration of their support, our investors have provided us with the funds necessary to secure success", said Faradion CEO Lawrence Berns. "We can now move forwards quickly to proving and scaling up our solid state low cost batteries and, indeed, intend to demonstrate one in a dynamic environment very soon
Faradion's sodium-ion technology is said to have already shown specific energy densities in full cells in excess of other known sodium-ion materials. In addition, the Faradion team has developed materials with energy densities exceeding those of lithium iron phosphate. According to the company, sodium-ion has an energy density of 700Wh/kg, a specific capacity of 160mAh/g and an average discharge voltage of 3V.
Faradion's technology is being applied within 3Ah prismatic cells, being supplied to Williams Advanced Engineering as part of a project cofunded by Innovate UK (see image, which shows a 48 cell battery pack).
