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. Mn 0.25 ]O 2 layered cathode (NFM), and NaClO 4 in fluoroethylene carbonate and ethyl methanesulfonate electrolyte. For the anode, they selected carbon-modified iron oxide (C-Fe 3 O 4 ) conversion material. Mn 0.25 ]O 2.

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.

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. Indeed, high-density, affordable, and efficient hydrogen storage is one of the key steps in the realization of a hydrogen-based energy sector.

Researchers develop rechargeable hybrid-seawater fuel cell; highly energy density, stable cycling

Green Car Congress

The circulating seawater in the open-cathode system results in a continuous supply of sodium ions, endowing the system with superior cycling stability that allows the application of various alternative anodes to sodium metal by compensating for irreversible charge losses. an alloying material), in full sodium-ion configuration.

CMU study concludes lithium market fluctuations unlikely to impact Li-ion battery prices significantly

Green Car Congress

Despite substantial cost reductions in recent years (59-70% per kWh between 2007 and 2014), lithium ion batteries are still significantly more expensive than the Department of Energy target of $125/kWh by 2022. They then performed a sensitivity analysis to determine the influence of large fluctuations in the lithium carbonate price.
