Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

With regards,

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 :

#   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

Replying to  
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

Replying to 
It's all known facts; only to a few.

Replying to 
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
