Currently reading about Grabat Battery tech
Quotes of interest:
"In the case of the automobile, he emphasized that the technology they use cannot be compared with the current lithium, since although the latter has an energy density of 180 Wh / kg “it is not real”.
Grabat batteries, which are going to be made in Yecla (Murcia) from March, have a density of 1,000 Wh / kg, a voltage of 2.3v and when they have been analyzed by the independent organisms TÜV and Dekra, haven’t exploded, as can happen with a lithium battery. In addition, after being short-circuited, they returned to work with 60% of the load, according to Martinez. According to the president, it has “a huge potential, since the loading and unloading speed is 100 C, while the one of a lithium is 3C, and it has no memory effect”. This means that, if the power grid allows it, a vehicle could be loaded in 5 minutes, with which you can drive – in the case of a sub-compact car – for 800 kilometers, compared to the 400 kilometers that – he said – offers Tesla cars or the 250 kilometers of a Nissan Leaf or a Renault Zoe."
The average kwh capacity of an electric car is around 59.8 kwh (see EV data sheet)
Or if you computing from energy density average battery mass with Grabat battery tech, we have
a battery 59.8 kg. This is around 132 pounds (imperial weight) incidentally. Could be a game changer tech with scale and lower cost manufacturing.
