RE: Sodium - Ion Cells

Dear Shri Gopukumarji,

The following news report reminded me of your R&D work on Sodium – ion Cells :

CATL's new sodium ion battery to help ease lithium shortages [ 03 Aug 2021 ] / Reuters

I hope CECRI continues its R&D on this and , hopefully ( someday soon ), license an Indian Battery Manufacturer to commercialize your invention. If successful , Na-ion battery could , not only be 50 % cheaper than the Lithium-ion batteries but with Na haing 300 times more presence than Lithium in earth, we would not have to depend upon foreign supplies

Wishing you luck,

With regards,

Subject: RE: Sodium - Ion Cells

Dear Shri GopuKumarji,

Just came across the following news report in today’s Business Line :

Govt-owned electrochemical lab cracks sodium-ion cell tech

It reads :

==================================================================================================

CECRI…..will be ready to license technology for the mass production of Sodium Ion cells, if things go as planned .

The production could be a big pep to Electric mobility because sodium-ion batteries cost a tenth of the conventional lithium ion batteries

Sodium, available in abundance in sea water, has long been a preferred option, but the metal is also tricky to handle due to its reactive nature.

The difficulty has not deterred scientists at CECRI from trying, who have already developed the technology for making lithium-ion cells and have offered to it to the industry.

Congratulations to your entire team on this “ game changing “ breakthrough – especially considering that ,

# India has no deposits of Lithium and must spend heavily to import it from Bolivia-China etc

# Extracting Sodium from our abundant supply of sea water is not an issue

I take the liberty to endorse this email to our :

Cabinet Ministers

NITI aayog

Members of PM’s Economic Advisory Council

Members of PM’s Scientific , Technology and Innovation Council

Trade Associations ……..etc

I urge the Central Government to take the following steps URGENTLY :

# Without waiting for the next Republic Day , announce award of Bharat Ratna to CECRI team

# Authorize CECRI to transfer this technology , FREE of any cost , to companies ( Foreign or Indian ) which set up

manufacturing plants ( under a SPV , exclusively for this purpose ) in India . These licensees shall be

prohibited from transferring this technology to any other Company anywhere

# No GST on Sodium-ion cells produced by these licensees , nor payment of any Corporate Income Tax for 10 years

for these Licensees

If for any reason , it is not possible to exempt the entire income from Corporate Income tax , then , at

least the income derived from exports of sodium-ion cells , should be exempted

I appreciate that it is too late to incorporate these announcements in tomorrow’s Union Budget

But , nothing stops the Government to make these announcements NEXT WEEK – or at least before the Election Code of Conduct kicks in by next month !

With regards – and admiration ,

Dear Mr Parekh,

Thanks for your mail and I am to say that at present CECRI does not work on Al/air. However, we did this work in 1985 to 1995 and gave up due to various reasons.

I have also seen the PHINERGY news and also the video and looks interesting.

Best Regards

Dear Shri Gopukumarji,

I read with interest following news report :

Huge demand for CECRI’s lithium-ion cells ,

Where you say :

If mass-produced, cells made with CECRI’s technology can be sold cheaper than those imported from China

Article also talks about development efforts going on , in respect of :

Sodium-ion cells

Lithium-Air , Lithium Titanium Oxide and Sodium Air , cells

In this context , no doubt , you might be aware that Ashok Leyland has tied up with an Israeli Company , PHINERGY , for development of Metal Air battery made of Aluminium

Is CERCI working on this ?

In this context , you might want to look up :
