Hi,
Still, the figure is amazing. A 52 kWh battery would only weigh
52000/2600= 20 kg, ~10 times less than Eestor's EESU of the same
capacity is supposed to weigh :)
I've been researching the lead cobalt alkaline battery, which has an
energy density of 109 watt hours per kilogram. According to the
patentee, this is similar to the lithium ion or metal hydride batteries.
The energy density that you're talking about is 20 times that.
