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.,

Battery Advances Over the Next Ten Years

My Electric Car

For example the volumetric energy density of lithium-ion batteries has increased eightfold since 2008, from around 55 watt-hours/litre to 450 watt-hours/litre in 2020. At the same time the cost of lithium-ion battery packs declined 87% between 2008 and 2021.

DOE announces $60M to accelerate advanced vehicle technologies research

Green Car Congress

VTO-funded research has reduced the cost of advanced batteries by 75% since 2008, and nearly every plug-in electric vehicle (PEV) on the road today uses VTO-developed battery technology. Advanced liquid electrolytes for lithium-ion cells under extreme conditions, such as extreme fast charging, and mechanical, thermal, or electrical abuse.

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). Both establishments have been collaborating closely on various scientific areas since 2008. 2017.10.023.

GWU researchers introduce new class of molten air batteries; significantly greater energy capacity than Li-air

Green Car Congress

These are the iron, carbon and VB 2 molten air batteries with respective intrinsic volumetric energy capacities of 10,000 (for Fe to Fe(III)); 19,000 (C to CO 3 2- ) and 27,000 Wh liter -1 (VB 2 to B 2 O 3 + V 2 O 5 ), compared to 6,200 Wh liter -1 for the lithium-air battery.
