A biological template ramps up electrode performance and scales down size.

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.
