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 :
# ROLE OF StoresDot
* Modify their FlashBattery Charger (
which is capable of charging an Electric Car
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

=================================
there is no charging of AluminumAir batteries as they are primary ( not rechargeable) batteries. One would have to replace the Al in order to have new capacity

==============================
It's all known facts; only to a few.
12:10 PM - 17 Jan 2018
=================================
parekhji if what you are saying here is true - this will revolutionise the EV market and will cause major upheavals world wide. More power to new technologies
