New Na-ion battery combining intercalation and conversion could be promising low-cost energy storage system

Green Car Congress

Scheme of the new full sodium-ion battery, which combines an intercalation cathode and a conversion anode. The reported performance of the new Na-ion battery suggests that the sodium-ion system is a potentially promising power source for promoting the substantial use of low-cost energy storage systems in the near future, the team concluded.

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.

Expanded graphite as a superior anode for sodium-ion batteries

Green Car Congress

Researchers at the University of Maryland, with colleagues at the University of Illinois at Chicago, report on a new method for expanding graphite for use as a superior anode for sodium-ion batteries in a paper in Nature Communications. Sodium (Na) is an earth-abundant and inexpensive element, and shares many properties with lithium.

Lux: Li-ion dominating grid storage market with 90% of 2014 proposals

Green Car Congress

Molten salt batteries still account for a majority of installations by energy capacity, because of NGK Insulators’ early lead, but are no longer the technology of choice, according to Lux. Li-ion accounted for 419 MW and 1,555 MWh of proposed storage systems in 2014. The “Grid Storage Data Tracker” is updated semi-annually.

RAL proposes new efficient and low-cost process to crack ammonia for hydrogen using sodium amide; transportation applications

Green Car Congress

RAL researchers are proposing a new process for the decomposition of ammonia to release hydrogen that involves the stoichiometric decomposition and formation of sodium amide from Na metal. To date, very few candidates show potential beyond that of the seminal work on titanium-doped sodium alanate. Credit: ACS, David et al.
