Batteries made for electric vehicles of today have a lot of issues. Aside from the fact that their life cycle comes with limitations, they do have other issues such as bulkiness too.
But Toyota seems to be on it as we speak, said to be in the developing stages of a new solid state and lithium ion batteries that would be more compact and able to store more energy which should make traveling on EVs more extensively and better.
The target date for the said technologies is still far off (try 2020). According to Toyota, “they achieve weight savings and better energy density than solid batteries by changing negative-electrode material into metallic lithium from black lead.”
