content: Looks a winner:Positive:- no fire hazzard- one minute full charge- 7500 cycles.Negative:2V per cell instead of 3,6V for LiIonhttps://news.stanford.edu/news/2015/march/aluminum-ion-battery-033115.html

content: 2V is fine, just put more in series.As usual, it looks good on paper but i'm not getting excited until i can order some.

content: Not sure about the fire proof claims, any one who has worked with aluminium knows about its flamability, aluminium powder is even used in explosives.

content: The energy has to go somewhere when you damage the cell.If breaking it open doesn't release the energy then you can beat something else will.

content: Quote from: G7PSK on April 07, 2015, 08:02:51 amI read the article twice and missed the "fire proof claims" both times. I did note they said "low flammability" and "Our new battery won't catch fire, even if you drill through it."Did we read the same article?There is a significant difference in fire risk between lithium and aluminium, but nobody seems to be claiming anything about being "fire proof".All in all, it looks like some significant progress in energy storage. Let's see if it actually pans out.

content: Depending on the particularly chemistry, Li-Ion can be safe:So are they comparing to the best of Li-Ion or the worst? (e.g., the cells Tesla use in their pack are "unsafe", but are made safer by placing them within a fire-resistant casing.)

content: Yet another new battery technology claiming it's great...Wake me up when I can buy one. You might need a shovel to pull me from my grave though.

content: Quote from: tom66 on April 07, 2015, 08:44:42 amLithium Manganese is about the best balance of safety and cost we have right now. (That's what is in the Leaf battery pack and the 18650 cells in your second video.)It simply smolders for a short period before self extinguishing.That's why, if you use an eCig mod you're pretty much asking for it if you don't use name brand (Panasonic, Efest, etc.) LiMn batteries. I don't know about you, but I don't want a potentially explosive battery inches from my face, while inhaling *and* drawing 1C from said cell.Sent from my Tablet
