Faradion and Phillips 66 to develop lower cost and higher-performing sodium-ion battery materials

Green Car Congress

Sodium-ion battery technology has an inherent advantage over other power-storage technologies because it uses low-cost materials that are sustainable and widely available. Prototype cells deliver energy density in excess of 140 Wh/kg, with a design performance of 155 Wh/kg in 10Ah pouch cells. Earlier post.).

BMW i home energy storage system integrates 2nd-life i3 vehicle batteries

Green Car Congress

Following in-vehicle usage, the BMW i3 battery retains most of its original capacity, thus continuing to offer years of emissions free power storage and expanding the sustainability concept beyond the individual vehicle life. The “plug and play” nature of the BMW i3 battery application in this system is a key element in its design.

INEES report shows intelligent integration of EVs reduces power fluctuations, but not currently economically viable

Green Car Congress

At the same time, batteries in electric vehicles offer large storage potential and thus can offer an additional way to compensate for these fluctuations. Pooling batteries of electric vehicles offers a power storage capability of significant size suitable for mass consumption, which can compensate for fluctuations in the power grid.
