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.

CATL, BYD's sodium-ion batteries both to be in mass production within this year, report says

CN EV Post

CATL and BYD's sodium-ion batteries to be put into mass production will both be a mix of sodium-ion and lithium-ion batteries, according to local media. Image credit: CnEVPost) BYD's progress in mass production of sodium-ion batteries does not seem to differ much from CATL's, although it has not announced the latest progress.

Researchers use in situ NMR spectroscopy to provide insight into silicon expansion in Li-ion batteries

Green Car Congress

This versatile nanowire-based technology can be applied to other battery system such as tin and germanium-based lithium-ion batteries and sodium-ion batteries, and studies are currently on going with the NMR spectroscopy under a wide variety of electrochemical regimes.

200 Years Ago, Faraday Invented the Electric Motor

Cars That Think

Faraday was an interesting choice for this task, as Nancy Forbes and Basil Mahon recount in their 2014 book. He had discovered sodium, potassium, and several compounds and invented the. But when Phillips asked Faraday to write the review article for the. For a good summary of Faraday's article, see Aaron D.

Vanderbilt/ORNL team discovers new form of crystalline order that could be attractive for thermoelectric applications

Green Car Congress

If you put a pair of sodium and chlorine atoms at each lattice point, they form sodium and chlorine sub-lattices and you get salt. When you have more than one atom at each point, each type of atom forms its own sub-lattice. For example, if you put a pair of carbon atoms at each point (forming two FCC sub-lattices), you get diamond.
