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

Univ. of Maryland team develops promising sodium-ion cathode material: FePO4/nanotube composite

Green Car Congress

Researchers at the University of Maryland have developed a nanocomposite material of amorphous, porous FePO 4 nanoparticles electrically wired by single-wall carbon nanotubes as a potential cathode material for sodium-ion batteries (SIBs). With a simple synthetic procedure, cost-effective chemicals, and desirable cell performance, the method offers a promising candidate for commercialized cathode materials of SIBs, the researchers suggest in a paper in the ACS journal Nano Letters.

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. The battery installation is connected to a nearby 11-megawatt wind farm owned by Minwind Energy, LLC. In addition, the technology needed to be commercially available and have a sound track record.

Researchers synthesize new Li-S cathode based on “carbon compartments”

Green Car Congress

Although interesting solutions have been proposed and successfully implemented, such as the use of nanostructured composite sulfur-carbon compounds with reversible capacities up to 1,320 mAh g −1 , the development of a Li-S electrode couple into a commercially-viable battery has been hampered by poor reversibility during discharge and subsequent recharge cycles.

WMG researchers use graphene girders to improve performance of Si anodes in Li-ion batteries

Green Car Congress

Although silicon is an abundantly available element with ten times the gravimetric energy density of graphite, several performance issues continue to limit its commercial exploitation. However, it also possible to separate and manipulate a few connected layers of graphene giving a material researchers refer to as few-layer graphene (FLG).

Porous Metal-Organic Frameworks Made from Food-Grade Natural Products; Edible MOFs for Gas Storage and Other Applications

Green Car Congress

The nodes of the lattices are complexes of transition metals (such as copper, zinc, nickel, or cobalt); organic molecules make up the connections between the nodes. Suitable candidates include ordinary table salt (sodium chloride), the common salt substitute potassium chloride, or potassium benzoate, an approved preservative. It is even possible to use commercially available sources such as grain alcohol. A rendering of an element of a CD-MOF. Click to enlarge.

Researchers call for integration of materials sustainability into battery research; the need for in situ monitoring

Green Car Congress

All these technologies have advantages in terms of abundance (sodium is 1000 times more abundant than lithium, and calcium 3000 times more) or in terms of recycling as with organic electrodes or binders obtained from natural resources such as CMC (carboxymethylcellulose). When the electrodes are externally connected, redox reactions proceed in tandem at both electrodes to deliver energy.

Zytek Shows Electric A-Class Demonstrator with Uprated 55kW E-Drive; Developed in 10 Weeks

Green Car Congress

The 55kW E-Drive fits neatly onto the existing engine mounting points with just three additional connections (water, high voltage electrics and low voltage electrics). Power is provided by two air-cooled sodium nickel chloride battery packs, integrated under the floor of the vehicle so they don’t compromise luggage space or vehicle stability.
