iFixit speculated that the tape is from Tesa. Tesa says it has filed "50+ patents for 'Debonding on Demand' adhesive tapes' … 'using various mechanisms such as temperature, electricity, laser and electromagnetic induction': https://www.tesa.com/en/about-tesa/press-insights/stories/debonding-on-demand.html https://www.tesa.com/en/about-tesa/press-insights/stories/de... So generic battery manufacturers could presumably buy the tape from Tesa, license production themselves, risk producing their own variants, or supply replacements without electrical debonding (the consumer probably doesn't care that the replacement battery doesn't use the same debonding tech their original battery used).
