Ion-lithium batteries

The electric propulsion used by different modes of transport requires powerful batteries which take up a lot of space. This is why it would be extremely useful to have batteries which could be adapted to fit different shapes in in order to maximise the available space. This is why we invented these “Lego” batteries. They can be assembled and connected in both spatial directions with a simple quarter turn, and once they are in place they can withstand the standard car impact tests and continue working.
