One of the simplest practical sources of electrical is Danielle Cell. It is contain a zinc electrode immersed in a solution of zinc ions (Zn++) and a copper electrode in a solution of bivalent copper ions (Cu++). Negative ions are also present but need not be considered for the moment.

NREL discovers new cellulose digestion mechanism necessary for biofuels industry
The National Renewable Energy Laboratory's (NREL) researchers have discovered a new mechanism that digests cellulose faster than enzymes from commercial preparations, and could prove to be a valuable mechanism for the biofuels industry.
The thermophilic bacterium Caldicellulosiruptor bescii uses an intermediate strategy, secreting many free cellulases that contain multiple catalytic domains; and one of these, CelA, includes a glycoside hydrolase family 9 and a family 48 catalytic domain separated by linker peptides, and three type III cellulose-binding modules.
"We are learning a lot about the evolution of these cellulases, how they can thrive in extreme environments, and how they operate on biomass."
Scientists at the US Department of Energy's (DOE) NREL have conducted a test on CelA and revealed that it produced more sugars, outperforming the most abundant cellulase in the commercial mixtures (Cel7A) when converting Avicel, a common cellulose standard.
When converting Avicel at its optimal temperature of 50°C, Cel7A has achieved only 50% of the performance of CelA, the NREL said.
