A Battery Revolution in Motion
Found on CNRS News on Monday, 30 November 2015
The first prototype of a sodium-ion battery has just been revealed by the RS2E, a French network bringing together researchers and industrial actors. This technology, inspired by the lithium-ion batteries already used in portable computers and electric vehicles, could lead to the mass storage of intermittent renewable energy sources.
Being three times lighter than sodium ions, lithium ions also make it possible to produce very lightweight batteries, an undeniable asset when it comes to portable electronics.
However, for the mass-storage of energy the weight itself isn't much of an issue. It doesn't really matter if you have a one ton block in your basement, or a three ton block; and for most portable devices it won't matter too much either.
