French battery-maker Saft Groupe SA has teamed up with researchers at the Université Paris Est to develop a solid-state battery with a high-capacity nanocomposite metal-hydride anode, sulfur cathode and lithium-borohydride electrolyte.
Touted as an industry first, the combination is said to provide greater energy capacity than current lithium-ion units but without the safety and recharging issues of other lithium-sulfur chemistries. The research team, which was funded under the European Union’s Seventh Framework initiative, detailed their work in the Journal of Power Sources.
Several research groups and carmakers, including Daimler AG, also are exploring the use of lithium-sulfur cells, which can store as much as five times the energy capacity of lithium-ion units. Additional benefits include good low-temperature performance and the ability to use of non-toxic materials.
