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.

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. They are able to store about 7.2

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. A paper on their work is published in the journal Small. El-Demellawi, J.

Almost all locomotives used today are powered by electricity, either generated onboard through a diesel engine or provided through a connection to the electric grid (third rails or overhead lines). Hybrid locomotives are an emerging alternative to these approaches that utilized stored energy from batteries.

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.
