I can't figure this out. It seems backwards to me.

In electrochemistry, If 0.215 Joules per milliliter is 100% efficient production then what percentage of efficiency is 8.0 Joules per milliliter which is obviously less efficient.

I can't say I have any knowledge of electrochemistry, but presumably you are talking energy input to produce a quantity of product. If 0.215 Joule per ml of product is 100% efficiency, then 0.43 Joule per ml would be 50% efficient. Your efficiency is thus 0.215 divided by your actual energy requirements. 0.215 / 8 = 0.026875, so that's 2.6875% efficiency.
