And the materials used in the current batteries are dug out of the ground
and rare and expensive. I think they are going to replace Lithium with song
else soon. I did wonder if you could just buy the battery, and a charging
circuit and an inverter, go on the cheap overnight charging rate offered and
then run the house during the day from the battery?
That would put the energy companies noses out of joint.
Quite right, Brain. Lithium technology needs to be dumped; it's really
a non-starter for extended use in heavy current-demand applications
such as vehicles. I'd wait until the alternative is implemented and we
can forget all about the nightmare of range anxiety and finding a
recharge source when out on a long run far from home. In ten years
time, we'll laugh in disbelief at the wretchedly poor capabilities of
this first generation of electric cars.
Have you seen the cost-reduction curve on Lithium batteries ?
Someone has been pocketing the savings.
The batteries are being improved, while you're
sitting there in your chair. Lithium batteries
have not been standing still. They have been getting
better with time.
Tesla bought the company that makes Ultracaps, and
bought them for only one reason. Their "dry process"
patent. This allows Lithium batteries to be made without
"drying ovens", which were a major energy consumer during
And it's not all Lithium Cobalt either.
"This makes fast recharging possible and
provides high currents when needed."
"Proterra, in its all-electric EcoRide BE35 lightweight 35-foot bus"
The Proterra bus, the idea is, it drives for an hour. A
pantograph connects the bus roof to a power source, and
the bus charges at its depot for ten minutes. Then does
another hour-long run. This allows the bus to do a
22-hour service day. The ten minute charge does not
count as a full charge cycle, so there is some
multiplier involved there.
That bus is being trialled here. They are sampling several
buses and it's one of the candidates.
This solves the pattern one of the competitors had, where
the other bus only "worked" for a four hour pattern or
so. The service pattern did not seem conducive to running
the buses all day long, like the current diesels handle
without a problem.
The bus technology won't be going to cars, because the
number of cells required would likely leave little
room for cargo inside a car. It's not that this technology
is a replacement for Lithium Cobalt. It's an example of
designing an alternate, that makes bus schedules possible.
The bus in question, isn't all that large, so would not
be an exact replacement for a bus that is on the road
What it would do for cars, is allow fast charging every
time you charged it. Versus the "limited" fast charging
offered now. Lithium Cobalt still has it beat on
