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

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. Comparison of commercially available electric vehicles driving range to recharge time (min) (for a full recharge), abbreviated as MPM (and for use akin to MPG).

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. It is even possible to use commercially available sources such as grain alcohol.

A nearly threefold decrease of the stored kWh price to €200 per kWh at the pack level is predicted in the next 10 years, driven at least in part by both the large volume production and the realistic prospects of a second life for electric vehicle batteries.
