General discussion of disadvantages of Li-Ion batteries and how we can overcome them

I want to model the Flow of Li ion in the battery as fluid, I am on it but i need the suggestions to deal it in best way. 

With the fast development of sodium-ion batteries (starting from ~2010.), is it possible that in the near future market share of Na-ion became comparable with today's state-of-the-art Li-ion counterpart?

Just out of curiosity, is there anyone current working on materials for cathodes for lithium ion batteries that exceed 5V vs Li?

in my case the material is self supported, binder and current collector free carbon nanofiber.

Aluminum is more abundant when compare to Li. It is commonly used as foils in the lab as well as in the hotel industry. The foils are disposed of after single use. If this material is used in battery, then the cost can be reduced significantly. This idea was mooted by one of my senior research colleague.

Currently some people focus the scale-up of Li batteries, while others shift to other style batteries, such as Na-air batteries. What is your view?

Please, send me an advise how to open a prismatic Li-ion battery cell in a safety manner. I plan to do it in a GloveBox under the N2 atmosphere. Concentration of O2 and H2O measured in the box is <0,5 ppm for both. Is there any risk in terms of short circuit, ignition, flame, etc., if I start to work with cells of 0% SOC filled with electrolyte.

Thank you very much in advance for your effort.

We would like to test automotive battery cell from Tesla Model 3, VW ID3, Porsche Taycan, BMW i3, Nissan Leaf and Daimler EQC. It is extremely difficult to get single cells. We would have to buy the whole battery packs for more than 10.000$.

Can anyone get single cells?

If not: Would other labs be willing to share the cells and costs?

We would buy the packs, tear them professionally down and provide you with cells.
