New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. The team previously reported a neutral molten salt reaction.

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

As the pressure to decarbonize electricity grids mounts, so does the need to have long-term storage options for power generated from renewables. Especially for sources like wind and solar, which have discontinuous availability. He expects the battery to retain over 80% of its charge in that period.

Energy storage: the key to a decarbonised future

Setec Powerr

We are transitioning from fossil fuels to renewable energy sources such as wind and solar, and the use of energy storage is becoming more widespread. Others solid battery types are nickel-cadmium and sodium-sulphur, while zinc-air is emerging. Technologies include energy storage with molten salt and liquid air or cryogenic storage.

Hydro-Québec and Technifin form partnership to license lithium titanate spinel oxide (LTO) technologies for Li-ion battery applications

Green Car Congress

Despite the low capacity of LTO (175 mAh/g) relative to that of graphite (372 mAh/g), lithium-ion cells with advanced LTO anodes are particularly attractive for a new, emerging generation of safe lithium-ion batteries to power hybrid electric vehicles and other mobile devices, as well as for stationary energy storage applications.
