New improved Aluminium-ion battery from Stanford University

From Stanford, April 6, 2015
Stanford University scientists offer Aluminium-ion battery as a safe alternative to conventional batteries:

Theoretical energy density. Bad citation. Hugely overblown numbers.

From cited source:

Because an aluminum battery is trivalent, it has a distinct advantage in its capacity for energy density over the existing lithium-ion battery (1060 Wh/kg vs. 406 Wh/kg).

From the article, citing said source:

the theoretical energy density for aluminium-ion batteries is 8140 W-hr/kg in comparison to lithium-ion's 1462 W-hr/kg.

I will correct the article to the data in the source. --89.146.158.19 (talk) 23:39, 8 April 2015 (UTC)

Electrochemistry

The cathode reaction is for a particular type of Al Ion battery including manganese and lithium in the reaction and the anode reaction includes chloring. This particular electrochemical reaction should be annotated to show which particular Li-Ion battery it relates to.Lkingscott (talk) 12:18, 12 January 2018 (UTC)

This article has many shortcomings and outright errors. The links to the Stanford University site are much more useful and accurate to boot. Spyglasses (talk) 02:48, 15 February 2019 (UTC)

Not sure why the author is confusing LMO reactions as a cathode reaction when it is normally used in the anode. The cathode is typically graphite. Mixing the two half reactions is clearly wrong. Refer the the linked article clearly differentiates this --Jedi2155 (talk) 23:30, 2 April 2019 (UTC)

The author for this section is confusing the readers here. The electrochemistry described here is for Al-Li hybrid battery system, not for traditional Al-ion battery. The cathode reaction typically uses graphite with the intercalation of aluminum based anions.

Inconsistency between Introduction and Challenges

At the beginning, the author implicitly states that the Al³⁺ ionic radius (0.54 A) is smaller the Li⁺ ionic radius (0.76 A). Although other sources offer slightly different measures (see here), this can be broadly confirmed. In the "Challenges" section, the author clearly states that "(....) One of the primary reasons for [the Al-ion batteries] short shelf life is the fracture of the traditional graphite anode, the Al ions being far larger than the Li ions (....)". Unfortunately, I am not in the position to offer a proven reason on why the Al-ion batteries have a short shelf life, but I don't think the reason offered by the author is valid.

I agree, and in fact find no evidence that Al-ion batteries even actually do have a short shelf-life. If the author instead means they have a short cycle-life, then the author is also wrong. All of the experimental batteries listed in the article have significantly longer cycle-lives than the state of the art Li-ion batteries. Phatgeek47 (talk) 03:47, 31 January 2020 (UTC)

Excess information

"Their cell provides about 2 volts, 4 volts if connected in a series of two cells." So, it will give a voltage proportional to the number of cells... isn't this trivial and should be deleted?150.227.15.253 (talk) 15:02, 16 February 2022 (UTC)

Help me REVEAL...

Aluminum expert? ¡Please HELP! I am trying to prepare an article based on the REVEAL model of a large tank of aluminum pellets for Seasonal thermal energy storage) combined with cogeneration and district heating I ask you please to come and play in my sandbox = edit, mess it about and comment on its talk page – thanks and salutations Timpo (talk) 09:22, 10 September 2022 (UTC)
