Argonne researchers find cathode material synthesis a key reason for performance degradation of sodium-ion batteries

Green Car Congress

One of the more promising candidates for batteries beyond the current standard of lithium-ion materials is the sodium-ion (Na-ion) battery. Na-ion is particularly attractive because of the greater abundance and lower cost of sodium compared with lithium. In addition, when cycled at high voltage (4.5

UNSW team proposes hard carbons from automotive shredder residue as anode material for sodium-ion batteries

Green Car Congress

Researchers from UNSW Sydney (Australia) report in an open-access paper in the Journal of Power Sources on the use of hard carbons derived from automotive shredder residue (ASR) as a suitable anode electroactive material for sodium-ion batteries (NIBs). The situation is much worse for graphite. Sarkar et al. 2023.233577

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. Thus, further research is required to find better sodium host materials. The sodium salt makes up the cathode; the anode is made up of phosphorous.

Graphene Jolts Sodium-Ion Batteries’ Capacity

Cars That Think

After years of anticipation, sodium-ion batteries are starting to deliver on their promise for energy storage. But so far, their commercialization is limited to large-scale uses such as storing energy on the grid. Sodium-ion batteries just don't have the oomph needed for EVs and laptops.

Tech Talk: How sodium-ion batteries could slash the price of EVs | Autocar Professional

Baua Electric

Given how fast things change in this business, chances are lithium-ion batteries – which have drawbacks in terms of sustainability, energy security and cost – will be overtaken by another type of energy storage. SIBs are benign, containing no lithium or cobalt, and sodium is abundant worldwide.

Chalmers team develops graphite-like anode for Na-ion batteries; Janus graphene

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a nanometric graphite-like anode for sodium ion (Na + storage), formed by stacked graphene sheets functionalized only on one side, termed Janus graphene. The estimated sodium storage up to C 6.9 Na is comparable to graphite for standard lithium ion batteries.

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. Arguably, this focus may have diminished the consideration of reversibility, cost, and practicality of use of these materials. Click to enlarge.
