UK engineer and former Royal Navy officer Trevor Jackson began
experimenting with aluminum air batteries at his workshop in the
Cornish town of Callington in 2001. At that time, the electrolyte used
was extremely caustic and poisonous. After years of experimentation,
Jackson devised a new electrolyte -- whose composition is a closely
guarded secret -- he says make it possible for his invention to power
an electric car for up to 1,500 miles. What happens when it runs out
of juice? You replace it with a new one while the old one gets
recycled. At the beginning of the electric car era when charging
infrastructure was nonexistent, the idea of swapping spent batteries
for fully charged new ones was considered feasible. Jackson says such
a thing could be the future, with his batteries/fuel cells sold at
grocery stores and retail outlets. He says the process of
disconnecting the old one and connecting the new one will take about
90 seconds.
[A]n independent evaluation by the UK Trade and Investment agency in
2017 said Jackson's invention was a "very attractive battery" based on
"well established'" technology, and that it produced much more energy
per kilogram than standard electric vehicle types, according to a
report in the Daily Mail. A Tesla Model S can drive up to 370 miles on
a single charge. Jackson says if you drove the same car with an
aluminum-air cell that weighed the same as the Tesla's lithium-ion
battery, it would have a range of 2,700 miles. Aluminum-air cells also
take up less space. If that same Tesla were fitted with an
aluminum-air fuel cell the same size as its current battery, it could
run non-stop for 1,500 miles. The report goes on to say that Jackson
just signed a multi-million dollar deal with Austin Electric, which
will begin putting thousands of the batteries into electric vehicles
next year.
"Austin Electric has three targets for the new batteries -- the
three-wheeled tuk-tuks used for transportation in many countries such
as Pakistan, electric bicycles with far more range than current
models, and a program that will convert front wheel drive cars with
internal combustion engines into hybrids by fitting aluminum-air
batteries and motors to drive the rear wheels," reports CleanTechnica.
"Jackson expects the conversion operation to start next year. He says
the cost of each conversion will be [...] about $4,000."
