This sounds like a small tweak in the manufacturing process that could lead to potentially very large gains down the road. Fantastic work!

- giuliomagnifico 4y agoYes exactly why I posted it. A little improvement that can be real in few time, instead of some groundbreaking researches that will never be used in daily life (in the next few years).
- abracadaniel 4y agoYou weren't kidding. Just switching out the tape material is all it takes? I wonder how frequently PET based tapes are used. I'd assume any of the pouch type batteries could be impacted, so phones/laptops/etc. Fascinating that it wasn't noticed until now.
- kazinator 4y agoWe shouldn't rush to the conclusion of large gains; this plugs a tiny leak which affects equipment that is used sporadically between long idle times, which is a specific use case. This could reduce the number of service visits to battery-powered, low-current-draw remote sensing equipment and such. In that sort of use case, it could be a big deal.
- hex4def6 4y agoExactly. This is not going to make a meaningful difference in devices that you charge on a daily / weekly basis (cell phones, laptops, smart watches). Additionally, there's a significant portion of "self discharge" of lithium packs that is actually the battery protection circuitry (BMS). That's not to say this isn't a good catch; like you mention, low power devices that you want to go months between charges may benefit significantly.
