The problem with the article is that it lacks substance. As an example, it mentions that al-ion has intrinsic advantages and disadvantages compared to li-ion, but it only talks about advantages. Aluminum-ion technology has intrinsic advantages and disadvantages over the preeminent lithium-ion battery technology being used in almost every EV today. What do calendar and cycle life in different conditions look like? How do weight/volume per unit power/energy compare with existing li-ion cells? And so on... It seems like they found a way to improve the energy density of the al-ion cells mentioned in this Stanford news story. https://news.stanford.edu/2015/04/06/aluminum-ion-battery-033115/ https://news.stanford.edu/2015/04/06/aluminum-ion-battery-03... But without more detailed specs, it's impossible to compare their cells to existing li-ion cells outside of the specific examples they are using.
