Um. Not really true. NiCad's energy density (MJ/kg) is ~0.15, NiMH batteries over doubled that, and Lithium Ion batteries can easily add half again over NiMH. There are trials with various materials right now which will add even more.
This isn't minimising things like intelligent cell-balancing, which has come into its own in recent years, but there have been advances in the basic medium as well - and fully working Lithium Air batteries have now been demonstrated.
