Chance discovery could extend battery life by replacing tape that causes self‑discharge

" tape, like Scotch tape, holds electrodes together... PET in tape decomposes and creates the molecule which shuttles between electrodes all the time causing self-discharge... replacing the PET tape with a more stable material that won't degrade can definitely help improve battery cells"
