I've long felt the true future of high energy density batteries lies with metal-air systems. Now it looks like one group is making real progress in zinc-air, power batteries:

ReVolt Technology Ltd, a technology company which has developed a rechargeable zinc-air battery (
earlier post), and BASF have entered a joint-development agreement to speed the development and commercialization of ReVolt’s rechargeable zinc-air battery system. Revolt’s zinc-air technology offers up to three times the energy density on a volumetric basis and twice on a gravimetric basis of lithium-ion, according to the company.
. . .
Now I've long felt the right answer was in a refractory temperature, liquid metal, air batteries. The higher temperatures promote the rapid chemical reactions needed to for power generation. The challenge of high temperature batteries is maintenance of the temperature and avoidance of heat loss. Still, this more temperate technology may work.
