Batteries From Wood?

It's one way of making microstructured electrolytes.

A local firm - Gelion - claims to be making a nanostructured electrolyte in a zinc-bromine battery as well as a nanostructured additives for lithium ion battery electrolytes.

Molecular biology is great at making molecules that living creatures use.

There's no suggestion that Gelion is following that route, and having more elements to play with that carbon, oxygen and nitrogen for the molecular backbone might be an advantage.
