IBM Almaden Lab Exploring Lithium-Air Batteries for Next-Generation Energy Storage

Green Car Congress

General schematic of a lithium-air battery. The team plans to explore rechargeable Lithium-Air systems, which could offer 10 times the energy capacity of lithium-ion systems. Original lithium-air batteries—aqueous batteries, or with an aqueous electrolyte/air interface—were primary cells—i.e.,

Jülich, ORNL researchers advance high energy density iron-air batteries

Green Car Congress

When it comes to volumetric energy density, iron–air batteries could perform even better with 9,700 Wh/l—almost five times higher than today’s lithium-ion batteries (2,000 Wh/l). The oxygen required for the reaction can be drawn from the surrounding air so that it does not need to be stored in the battery.
