I understand that some technology is kept secret for competitive reasons, but it seems to me that what is shown here (composition of batteries) could also be found out by simply opening one, of course assuming a somewhat expert is doing it. Or is there something preventing this?
On the other hand, revealing causes of failure seems much more specific and valueable, so there's that.
- Zak 10y agoThe basic structure of Li-ion batteries is well known and not really different between manufacturers and physical configurations (e.g. cylindrical versus pouch cells). What's significant is the details. The exact chemical compositions and dimensions of the different components result in significantly different performance characteristics.
- nolok 10y agoA relatively small number of batteries had the issues. The one we knew for sure had, well, burned or exploded.
