It seems like lead battery technology doesn’t get its fair share of
attention. Especially in Australia where we have the required resources
and industry for the whole product lifecycle.
When talking about large, stationary batteries, many of the benefits of
Lithium break down when compared to good'ol lead acid technology.

**Lithium batteries are likely to be an interim step. Aluminium
batteries look far more interesting and are much safer than lithium,
higher energy density than Pb and significantly lower mass:

Sound interesting, but note that aluminium is actually flammable. It is
a component of thermite, and you could ask the royal Navy what happened
to the aluminium superstructure of their ships that got hit by Exocet
missiles in the Falklands war.

no more flammable than lithium.

no more flammable than lithium.

**MUCH, MUCH less flammable than lithium. Lithium reacts with water and
oxygen readily. Aluminium, much less so.

It is less reactive than lithium but aluminium is an extremely reactive
metal, the only reason that it is stable under normal circumstances is
that it instantly forms a layer of oxide in the presence of oxygen (a
process called passivation).
