Ann: LIS Completes IPO to Commercialise Li-S Battery Technology, page-130

I think a phone will use tiny tiny amounts of BNNT. I remember seeing a picture of a large garbage bag full of graphene and it weighed about 1kg from memory. This stuff is like air. we would be on par with that i guess.
You can imagine how many phones that translates into. It is a nanomesh and mirco covering per battery so we are looking at massive numbers per kg. I would imagine we are talking mega numbers at 50kg per machine. PPK can make endless cheap machines/ Modules to make any quantity required now they have cracked the code. All that means lower overall costs.
