I found this review article by reviewing citations of this open access paper: "Giant nanomechanical energy storage capacity in twisted single-walled carbon nanotube ropes" (2024) https://www.nature.com/articles/s41565-024-01645-x https://www.nature.com/articles/s41565-024-01645-x .. https://scholar.google.com/scholar?start=10&hl=en&as_sdt=5,43&sciodt=0,43&cites=17954285623034023475&scipsc= https://scholar.google.com/scholar?start=10&hl=en&as_sdt=5,4... > 583 Wh/kg > Abstract: [...] Here we produced SWCNT ropes wrapped in thermoplastic polyurethane elastomers, and demonstrated experimentally that a twisted rope composed of these SWCNTs possesses the remarkable ability to reversibly store nanomechanical energy. Notably, the gravimetric energy density of these twisted ropes reaches up to 2.1 MJ kg−1, exceeding the energy storage capacity of mechanical steel springs by over four orders of magnitude and surpassing advanced lithium-ion batteries by a factor of three. In contrast to chemical and electrochemical energy carriers, the nanomechanical energy stored in a twisted SWCNT rope is safe even in hostile environments. This energy does not deplete over time and is accessible at temperatures ranging from −60 to +100 °C.

What are some possible carbon-based, compostable, inflammable alternatives to polyurethane elastomers for wrapping (multi- or just plain) single wall carbon nanotubes that store energy without loss?

Also from the gscholar "Cited by" list for that paper, I just found: "One‐Step Transformation of Single‐Walled Carbon Nanotube Networks into High‐Performance Multilayer Graphene‐Rich Films via Laser Shockwave Compaction" (2025) https://advanced.onlinelibrary.wiley.com/doi/abs/10.1002/adfm.202511015 https://advanced.onlinelibrary.wiley.com/doi/abs/10.1002/adf... Rhombohedral trilayer graphene, Rhombohedral pentalayer graphene, and Twisted bilayer graphene all demonstrate superconductivity. Can laser shockwave compaction transform carbon nanotube networks into superconducting processor components?
