This all sounds really great if they pull it off.
with 4 X the capacity at 1/4 the cost with greater life. Tesla is involved - trying to break the KW-hour holey grail.
The battery, which is now patent-pending at the US and other patent offices, is expected to cost less than $100 per kWh (about one-fourth that of the best batteries today), to weigh less and therefore provide longer range to cars, to have a greater power density (power to weight ratio), have a faster charging
time and much longer life.
