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.). Earlier post.).

New Li-S battery shows cycle performance comparable to that of Li-ion batteries along with more than double the energy density

Green Car Congress

These promising behaviors may arise from a synergistic effect of the enhanced electrochemical performance of the newly designed anode and the optimized layout of the cathode, they suggested. The cathode consists of an activated carbon?sulfur 750 mAh g –1 over 500 cycles (85% of the initial capacity). Credit: ACS, Lee et al.
