Nihl but scientists have now found that a pure Lithium Battery will yield the best results by far and have refered to them as the "Holy Grail" of smart batteries
“Some call it the Holy Grail. It is very lightweight and it has the highest energy density. You get more power per volume and weight, leading to lighter, smaller batteries with more power.”
There are still a few issues to resolve but given Lithium is the gold standard in smart batteries it makes sense to assess the viability of increasing efficiencies with the existing tech rather than starting fresh with VRB
