EV
juice from Alu-Air Battery ?
Modiji
is our TEAM
[
TEAM = Technology Evaluation and Acquisition Minister ]
In Aug 2016 , in my following blog , I
talked about an Israeli company , Stores Dot , which is working on
developing a Lithium-ion Battery for Electric Cars ; a battery that can be
charged in 5 minutes !
I
wrote :
Battery in 5 MINUTES ) , to be
able to charge GeoOrbital's replaceable
battery
pack , within ONE MINUTE
In
a subsequent following blog , I urged that India obtain this technology
from Stores Dot :
Need of the hour ? : TEAM

Online and offline media mention that , yesterday , Indian
Oil Corporation signed a MOU with an Israeli company ,Phinergy Ltd , for
development of Aluminium–Air Battery for Electric cars
Following are the media reports about that battery :
· Phinergy
has patented a "nano-porous silver-based catalyst", which allows
oxygen into the electrode and the cell while at the same time blocking carbon
dioxide. The company claims that this invention enables its battery cathode to sustain 25,000 working hours, while significantly
reducing weight.
· More
importantly, with its stable air electrode, any Phinergy metal-air battery
would not have to use pure oxygen, as is the case with most lithium-air
technologies. That leads to huge reductions in battery size and weight.
· Phinergy’s
technology can breathe oxygen from ambient air, allowing a high-capacity
battery with low weight
· The
aluminum-air battery would work in tandem with a lithium-ion main battery,
recharging it to extend the range of hybrid and electric vehicles by 1,000 miles
And
from web site of Phinergy :
Phinergy’s
air-electrode technology has enabled it to master the metal-air reaction
process and develop an aluminium-air system with a lifespan of thousands of
working hours, relieving the main constraints of electric transportation and
clean distributed generation.
Am I right in assuming ?
· There
will be no “ charging “ of this battery using Electric Charging Stations
· Charging
is through its built-in “ Air Electrode “ being injected with oxygen ,
extracted from air , even as the car is running – eliminating need for millions
of Charging Stations that India would require to completely switch-over to
Electric Vehicles ( using Li-ion batteries ) by 2030 . Hence no “ Range Anxiety
“ ?
If
yes, this would remove the biggest hurdle to early adoption of Electric Cars by
the
buyers and make it possible for quick transition from IC engines !
· Its
Cathode will need replacement after 25,000 hours
· If
battery is used ( on average ) for 2.5 hours per day, then that means , it
would need to be replaced after 10,000 days ( 30 years ? )
· Battery
needs to have 1 of kg Aluminium to generate 8 kwh . So , to generate 50 kwh (
rumoured capacity of TESLA Model 3 electric car ), it would need about 6 kg of
Aluminium and make it extremely cost-effective !
· It
can be “ re-charged “ ( with oxygen ) in 5 minutes ( while car is running ? )
· After
each recharge , it can run for 1,000 km
· As
compared to Lithium-ion battery costing 30 % of the cost of an Electric car ,
this Aluminium-Air battery would cost , hardly 5 % . Can this be true ?
· Once
this technology is “ localized “, will Indian Oil make it available ( free of
royalty or lump sum fee ) , to any Indian Manufacturer for commercialization ?
This is crucial for reaching 2030 goal-post
· Using Aluminium-Air battery , what would be the on-road
price of a standard 4 seat electric car ( such as M&M e20 ) ? Can it
possibly drop from Rs 11 lakh to Rs 8 lakh ?
· Will EESL insist that this technology be incorporated
in cars to be offered against its balance of 9,500 cars ?
I urge IOC and Shri Nitin Gadkariji to provide
unambiguous answers to these questions , which will educate the public and help
AUTO MANUFACTURERS to align their plans
