More range or more space
Panasonic, the supplier of battery packs for Teslas that are built in the US, hopes to make a big step in the field of battery capacity in the coming years. That should increase by 20 percent by 2030 at the same volume.
Reuters, which publishes this news exclusively, says that such a step with a Model Y just gives 100 kilometers extra driving range. Because it concerns extra capacity within the same volume, there are no sacrifices in terms of space or consumption. Of course, car manufacturers can also approach such a higher energy density in a different way. Then the same battery capacity provides more interior space and perhaps less weight, because a battery can then be reduced in size. With a 20 percent higher energy density, Panasonic would arrive at 900 Wh per liter of volume, compared to 750 now.
In this case, Panasonic is not using major innovations such as ‘solid-state’ batteries, which are reportedly also on the way. Instead, the Japanese company is aiming for a higher voltage per cell, made possible by new additives to the battery ingredients package. The danger of such a step is that the battery loses capacity more quickly, but Panasonic would have found a way to compensate for that degradation. We wait patiently!
