Work on NiMH batteries began at the Battelle-Geneva Research Center following the technology''s invention in 1967. It was based on sintered Ti2Ni+TiNi+x alloys and NiOOH electrodes. Development was sponsored over nearly two decades by Daimler-Benz and by Volkswagen AG within Deutsche Automobilgesellschaft, now a subsidiary of Daimler AG. The batteries'' specific energy reached 50 W·h/kg (180 kJ/kg), specifi
