Talk:Sugar battery

Sugar fueled batteries were not invented in 2014, only a specific type
There were many types of batteries fueled by sugar, the one described in the wikipedia article, invented in 2014, has its sugar catalyzed by enzymes in a specific manner but before this there were other types of sugar based batteries, some having the sugar decomposed by bacteria discovered in sediments ( Rhodoferax ferrireducens) like for example this press release from Oct 2003, pp 1229 - 1232 in "Nature Biotechnology" which states that a sugar based battery device was developed, based on "direct oxidation of glucose in mediatorless microbial fuel cells" http://www.nature.com/nbt/press_release/nbt1003.html. If you look into the subject, there were other concepts and prototypes of sugar based batteries before the 2014 invention. I propose that they all be classified according to the date they were invented and the type of reactant or organic catalyst them employ to breakdown the sugar which implies to classify also by type of breakdown process and what type of sugar is compatible, for example, the 2014 device is based on a man-made enzyme and uses a maltodextrine solution as the fuel source, at least according to the claims. — Preceding unsigned comment added by 82.240.163.245 (talk) 15:33, 3 March 2015 (UTC)


 * Why don't you go ahead and expand the article? SpinningSpark 06:58, 5 March 2015 (UTC)

Unit issue
"They have an energy storage of 596 Ah kg−1" <- Ah is not a unit of energy. (I suppose it should also say "energy storage density".) — Preceding unsigned comment added by 85.227.142.250 (talk) 13:21, 21 August 2016 (UTC)

I don't want to be the one to do it, but this article needs a serious de-hyping 2600:1700:B2F0:11B0:5421:575A:1B10:BC71 (talk) 05:25, 19 January 2021 (UTC)


 * Good catch, and yes, article needs work.

Enzymeless sugar fuel cells
The title is Sugar battery, but the subject appears to be sugar fuelled fuel cells. Furthermore, the subject only describes enzyme based sugar fuelled cells and not enzymeless sugar fuel cells. E.g. https://www.researchgate.net/publication/236654034_Enzymeless_multi-sugar_fuel_cells_with_high_power_output_based_on_3D_graphene-Co3O4_hybrid_electrodes Lkingscott (talk) 13:31, 17 September 2021 (UTC)

Relatively low voltage
Drawback of 'relatively low voltage'? Doesn't make sense. Who cares what the voltage in a single cell is? You can stack the cells electrically in series to create a battery of whatever voltage (limited by number of cells and their voltages) as you like. A car battery for example is only '12 volts' (really about 13.2) because it is composed of six cells connected in series.

Someone should fix that part of the article.
