Volumetric energy density: 530 Wh/L. So three times would be 600Wh/kg and 1590 Wh/L.
They observed reversible capacity ranging from 600 to 750 mAh/g, which is about
twice that of current carbon-based negative electrodes. The charge and discharge capacities stabilized at 600 mAh/g over 20 cycles. The cell was found to sustain and deliver 94% of its theoretical capacity at a rate of 1.12 C and 65% at a rate of 5.19 C, demonstrating the capability for high cycling rate. We believe that the power of the cell can be further increased by alternating stacks of nanowire monolayers and polymer layers of LPEI and PAA or other polyions. In addition, the
Au-Co3O4 hybrid nanowires should also increase the total capacity.

They created 10-centimetre-long anode sheets. The genetic material added to the viruses can easily be interchanged, the researchers say, so it should be relatively simple to create other electronic components, including a positively charged battery electrode (cathode) using the technique. Belcher is currently investigating how to use viruses to create self-assembling solar cells.
