Ohm - The car battery is finally evolving
Supercap battery for cars. Lower total storage, so engine off accessory usage is limited. But, it is smart enough to preserve supercap charge to start the engine. So, if you want a lighter battery, don't use other electronics much when the engine is stopped, and are possibly a cheapskate, this might be appealing.

A laptop battery system that knows your habits and lasts a lot longer - Next at ...
Software Defined Battery, as in the battery pack is smart and feeds from specific cells based on consumption profile, such that basic use feeds from more longer lasting cells, while peak usage uses peaking cells with a different chemistry/lifespan. I suppose this could also incorporate prismatic capacitors as well.

Clarion Labs rotary piston generator
See US patent application 20110133486 for the integrated generator in the wankel rotor. They claim to use the integrated generator to fiddle with piston rotation timing to improve efficiency (loiter at top dead center?), no permanent magnets due to an inductive layout,and ceramic apex seals.

Lithium-antimony-lead liquid metal battery for grid-level energy storage : Nature : Nature Publishing Group
Apparently swapping in a lead-antimony alloy for one electrode works pretty well, retaining the high voltage capability of pure antimony while lowering the melt temp closer to lead. Matching with a lithium electrode on the other side of the electrolyte makes the overall system operating temp lower, from the original concept's 700C to more like 450-500C.

Gravity Battery Concept
The major costs driver is the cost of drilling the holes and lining them. A thinner tube is cheaper, but requires a longer tube. Oil drilling technology has really come along, so this is easier. Cast concrete slugs seem to be the cheapest mass.
