A year or so ago, aluminum ion batteries were mentioned. As I recall,
higher energy density than litium cells.

Battery technology must be a lot more complex than it seems because real breakthroughs in performance are rare.



Many modern gadgets need a high current flow = a lot of heat is
produced. When mechanical cameras just needed a couple of button cells
for the metering, the current drawn was tiny.
