A nice achievement from the Toyota lab: they developped the prototype of a solid state Lithium based battery for an electric vehicle, the holy grail in the drive train according to some.
The new design allows for more power to be stored and less weight to be carried along. On top of it, the battery is also said to be more stable. When the conventional lithium based batteries exceed a certain temperature, they boil and are irreversibly damaged. When the solid state Lithium is in its ideal state it can manage higher power flows more easily. Get us more of those batteries I'd say!
Drive safe and sustainable!
