Great news! EV sales in #India surpass 150,000 units for the first time in May 2023. An outstanding annual growth of 64% compared to last year 2022. Market observers as well report a sharp rise in #electric two-wheeler sales due to national subsidies, an exanding #charging #infrastructure and declining #cell prices.
As Asian and Western #battery manufacturers see India as a super attractive consumer market, India itself is trying to empower its own domestic battery producers. According to Prof. Amreesh Chandra, a growing part of India's young battery industry takes a bet on a specific domestic battery material mix: #Sodium-ion batteries.

These cell innovations rely on #sodium #carbonate, sodium #hydroxide (electrolyte) as well as #aluminum (current collectors), #iron #phosphate (cathode) and #hard #carbons (anode). "All of these materials can be mined, produced and deployed by companies in India, says Prof. Amreesh Chandra. His research at the #Indian Institute of #Technology (IIT) proves the following advantages of sodium ion batteries for electric bikes:
India's Sodium-Ion Batteries
1) Enough energy density for #electric #bikes
2) ~30% cheaper than lithium-ion battery imports
3) Sustainable #mining, #production and #manufacturing
4) Great #rechargability #power #density characteristics - วิทยาศาสตร์และเทคโนโลยี

The professor is right, every country should manufacture sodium batteries, especially when they rely on desalination! Brine is a harmful waste, making batteries out of it will subsidize desalination, making water cheaper as a bonus! A triple win!
Absolutely 💯
Sodium is made from soda ash not salt
Thank you so much for a great talk, Prof. Amreesh Chandra!
We‘re stunned by these developments! Keeping fingers crossed for your goals!
i think this is great news. making smaller cells for e-bikes in india is a good starting point for that tech to mature. and if it has proven itself at scale, then the car industry will be highly interested to use it in bigger cells the get the cost down. maybe at the end we can achieve 50€ per kWh or even less.
Thank u India 🇮🇳
Da bin ich überrascht, klingt alles sehr gut. Die Leistungsdichte ist fast zu gut.
Interesting that his batteries are not meant for cold weather (mentioned at 22:32, „aqueous based“, not meant for below 10C). I was looking forward to Sodium batteries because I’ve heard multiple times that they could perform better in winter than lithium based ones (less capacity reduction in winter). Apparently not all variants of sodium batteries have this advantage 😢
but probably good enough for an indoor storage system. and the fact that you can discharge it to zero is wonderful for simple home electricity storage systems. it will be a game changer for smaller solar systems like balcony solar systems where your balcony could provide 1000Wp or more. Usually you have the dilemma between having a few solar panels without a battery where you give away the electricity for free when you can't use it. Or you have an expensive battery and you can use the energy from your solar system 100% by yourself.
both scenarios are not satisfying. but if you can save on battery cost, then the solar system with batteries is a financially attractive solution and will also smooth out the load on the grid especially if dynamic electricity cost are available for the customer.
Will work with heatpumps
Congratulations on your well-deserved promotion!
Well deserved new beginnings on the way
How and where any one can purchase it and the cost of the batteries.
80% of 2 stroke auto rickshaws (tuk tuks) are replaced by 4 stroke auto rickshaws, not by battery driven ones.
👍that is what you call... COMMON SENSE !
👍 Good luck. It will benefit everybody, and maybe will stop the wars and killing each other. Maybe we gonna come back more to spiritual life, and enjoy the time in life better... rather than killing each other supiditly.... life is to short to waste it for wars... technology should serve peace on earth...and more respect to each other. 👍
We want security to be of prime importance. Battery of my bike not blowing up in my house is of highest priority while thinking about the bikes. How will that be addressed?
Really great achievement Best wishes...
He should have shown a small demo video of his batteries
I use SIB s with my scooter and they're really great long life and fast charging.
No fire 🚒 risk like LIBs. I charge at 30 amp. Average time 40min.
Good for India. Maybe it will lead the way in high level manuafacture of sodium batteries and exported to the West, who seem not to be able to manufacture things on scale.
Thanks for explaining about revolutionizing of energy technology of batteries.
lead acid battery (90%) beats lithium battery (10%) on all low power ev until now
Which company by made sodium iron batteries.
What is enough current density of Sodium ion battery?????
Replace lead acid battery with sodium-ion battery quickly on all low power ev
Hello from a new subscriber :)
Welcome to our channel, hyric8927 👍🏻
I loved this episode. I wish them best of luck. But I must say it is one thing to produce few prototype cells in a lab but diffrent animal producing commercially at GWh scale. Going from lab to commerical production you have to cross a huge chasm that I call valley of death. Fingers crossed. My best wishes and prayers are with you.
The freezing of the sodium based cell is a problem obviously anywhere it might encounter freezing temps. At least 1/2 the worlds popluation is in areas where they counter freezing tempratures. It might be possible to have a warming system but it would have to be on at all times during freezing temps.
Heatpumps
Hardly 20% of world population is in freezing range. Africa, SAsia, Far East S America mostly are not freezing.
what about weight of the battery Sodium is heavier than Lithium ryt???
Do I understand correctly at th-cam.com/video/vom2PhrxEzA/w-d-xo.html , that Prof. Chandra said that their Sodium Ion coin cell have regenerative properties if a special refresh charge is applied? Or in other words, their Sodium Ion batteries last basically forever but have to go every 1000 charging cycles through a refresh cycle that restores the original capacity ? O_ô
renew the electrolytes and electrodes after 1000 charging cycles and you are good to go.. I think this is what he said.
China has to allow 5 percentage rate reduced give battery and technology to other country
At the start of the video Amreesh explains very clearly on detail what he is doing. I am not happy to hear Lennart ask Amreesh if everything he has talked about is correct! There is no purpose to ask anyone in a podcast this question unless you have no idea how to make interesting conversation for podcast listeners. All viewers understand Amreesh's plans to produce a battery nobody is confused if that os true so no need for asking people you are interviewing to repeat what they told you already and waste their time explaining it again and wasting viewers time
Haven’t China’s sodium ion batteries already been commercialized and been installed on EVs for the market?
