Stanford University: Lithium/graphene “foil” makes for a great battery electrode – 2X current Energy Density

Graphene handles the issues that come with an electrode’s lithium moving elsewhere.

Lithium ion batteries, as the name implies, work by shuffling lithium atoms between a battery’s two electrodes. So, increasing a battery’s capacity is largely about finding ways to put more lithium into those electrodes. These efforts, however, have run into significant problems.

If lithium is a large fraction of your electrode material, then moving it out can cause the electrode to shrink. Moving it back in can lead to lithium deposits in the wrong places, shorting out the battery.  Read More …
