Sodium-ion batteries are set to spark a renewable energy revolution – and Australia must be ready – ET Auto

Baua Electric

The extent to which renewables should dominate Australia’s energy grids is a major issue in science and politics. Solar and wind are clearly now the cheapest form of electricity. But limits to these technologies can undermine the case for a renewables-only electricity mix.

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. of peak charge capacity.

New liquid alloy electrode significantly lowers operating temperature of sodium-beta batteries; improved performance

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have devised an alloying strategy that enables sodium-beta batteries to operate at significantly lower temperatures. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. The rise of renewable solar and wind power is demanding sustainable storage technologies using components that are inexpensive, Earth-abundant and environmental friendly.

Xcel Terms First Phase of Sodium-Sulfur Battery Wind Energy Storage Test Project Successful

Green Car Congress

In October 2008, Xcel began testing a one-megawatt sodium-sulfur (NaS) battery ( earlier post ) to demonstrate its ability to store wind energy and move it to the electricity grid when needed. Results also indicate that this technology may be applicable for solar energy. Minimum of 300 annual charge-discharge cycles.
