Recipe for using viruses to make an electrode:

Dip a polymer electrolyte in a solution of genetically engineered viruses.

These form a uniform coating on the electrolyte.

Dip the coated polymer into a solution of battery materials.

The viruses coat themselves with the battery material, transforming into nanowires with a regular crystal structure good for high-energy batteries.
