incorrect values[edit]

Some values defined in column "Theoretical specific energy Wh/kg (excluding oxygen) are incorrect. For example, for Iron, value defined is volumetric energy density in Wh/l, but not in Wh/kg. Please, review and correct values respectively. — Preceding unsigned comment added by Liudas Tumonis (talk • contribs) 10:28, 28 November 2015 (UTC)[reply]

inconsistent values[edit]

the article states the energy density of gasoline to be 44 MJ/kg. However, the linked article on petrol density lists 42.4 MJ/kg; at one of these is wrong.

Energy density depends on what is in gasoline. For example alcohol lowers energy density. Both values could be correct. — Preceding unsigned comment added by Jkn2 (talk • contribs) 12:23, 27 February 2017 (UTC)[reply]

broken link[edit]

Ref #1 leads to a 404 error. — Preceding unsigned comment added by Alondana (talk • contribs) 19:14, 26 February 2013 (UTC)[reply]

fixed. -5.66.106.4 (talk) 09:38, 13 October 2013 (UTC)[reply]

graph-table discrepancy[edit]

There are major discrepancies between the energy densities depicted on the bar graph and those listed on the table. — Preceding unsigned comment added by 24.154.227.79 (talk) 21:44, 9 March 2013 (UTC)[reply]

Yeah the chart should sensibly be using the data from the table column including oxygen content - realistically they're going to contain impurities. (e.g. zinc air are much more comparable with lithium ion than one would think after a glance at the chart - at least in the mind of manufacturers) -5.66.106.4 (talk) 09:38, 13 October 2013 (UTC)[reply]

Removed the bar graph, it has no merit! Just look at Beryllium vs Lithium, no way. ElectroWolf (talk) 21:14, 29 November 2018 (UTC)[reply]

Misleading sentence[edit]

Misleading sentence: "Since oxygen is not stored in the battery, the theoretical specific energy excluding oxygen is 11,140 Wh/kg"

In fully discharged battery oxygen is stored in metal oxide. So fully discharged battery is heavier. 5210 Wh/kg would be better for Li-air. — Preceding unsigned comment added by Jkn2 (talk • contribs) 12:33, 27 February 2017 (UTC)[reply]
