You can use the fiber reinforced adhesive tape:

There are so many.
For 1mm and above thickness silicone sheets:

USA - Is it still legal to use asbestos?
Although asbestos is no longer mined in the U.S. and its use has declined significantly, American industry still legally imports, uses and sells both raw asbestos and products made with it. ... Many Americans mistakenly believe that asbestos was banned decades ago.
UK - In 1973, under the EPA's Clean Air Act, most spray-applied asbestos products were banned for fireproofing and insulating purposes. And in 1989, the EPA issued the Asbestos Ban and Phase Out Rule, which hoped to impose a full ban on the manufacturing, importation, processing and sale of asbestos-containing products.17 Sep 2012

It does not burn, it can be resistant to very high temperature and high voltage. Its downside is that it is not good for heath. But it lies inside the box all time. That might not be a big problem.
I bought this amiang sheet for just $5. Its size is 1.4m x 1.0m, its thickness is 0.5mm. And it is already solid like bulletproof (you will not need thicker). If your box is made of metal, you can also stick amiang sheet inside for electrical isolation.
And the silicone sheets I bought are not as expressive as your links above. I bought 2 sheets 0.5mm and 1mm, each is 1mx1m. As I remember, the 0.5mm was $15, the thicker 1mm was cheaper, around $10. I finally used the 0.5mm because it was already solid enough and saved some space. But 1mm would be still fine too.

Just charge each. Then remove say, 20% of the charge from each.

Thinnest common size is 0.6 mm, and price is low from there up to 1.6 mm thick. Thicker than this and the cost skyrockets. I would think that the 0.6 mm would be more than enough. Cut by scoring with a laminate cutting knife and then flexing to break it - using a saw or dremel is not as neat and fiberglass dust is not a good thing to breathe. Of course, if you have access to a metal-cutting type shear, that's the quickest and neatest way to cut the stuff.

They like to be half charged. Or a bit more. They dont much mind being at 30 to 70% charged. Long term. They will tolerate 80% for months on end.
Its a bit like breathing. Breath in with a maximum full breath. You are fully charged, but uncomfortable. You would rather breath out a bit! Esp after a while waiting. Same when you empty your lungs. Its not pleasant. The lithiums feel the same! Its why they are never shipped fully charged.
