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.

KAUST uses laser pulses to boost performance of MXene electrode

Green Car Congress

Graphite contains flat layers of carbon atoms, and during battery charging, lithium atoms are stored between these layers in a process called intercalation. These nanodots, roughly 10 nanometers wide, were connected to the MXene’s layers by carbon materials. Resources Bayhan, Z., This offers several benefits. El-Demellawi, J.

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. Reduce the need to compensate for the variability and limited predictability of wind generation resources.

The size of these batteries (in comparison to those used for portable electronics) places severe pressure on materials resources. Elemental resources. When the electrodes are externally connected, redox reactions proceed in tandem at both electrodes to deliver energy. —Grey and Tarascon. Source: Grey and Tarascon.

OSU smart membrane could enable new category of high-energy, high-power energy storage for EVs

Green Car Congress

The shelf-life of stored charge in rechargeable devices does not scale linearly with maximum SP and has led to trends referred to as ‘range-anxiety’, ‘compulsive charging’, etc. A control circuitry is connected to the membrane separator regulate the ionic impedance and ion transport between the electrodes.

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. Within their pores, the MOFs can store gases such as hydrogen or carbon dioxide. Metal-organic frameworks (MOF) are well-ordered, lattice-like crystals. Smaldone et al.

DOE Awarding $620M for Smart Grid Demonstration and Energy Storage Projects

Green Car Congress

Improved energy storage technologies will allow for expanded integration of renewable energy resources like wind and photovoltaic systems and will improve frequency regulation and peak energy management. The 1 MW/4hr system will store potential energy in the form of compressed air in above-ground industrial pressure facilities.
